Advisory Circular (AC) NO. 120-53, ``Crew Qualification and Pilot
Type Rating Requirements For Transport Category Aircraft Operated under
14 CFR part 121.''
On May 13, 1991, the FAA issued AC 120-53 to provide guidance on
the process the FAA uses when determining the level of flight crew
training required to operate an aircraft under 14 CFR part 121. The
regulations establish requirements for training, checking, and recency
of experience for flight crews operating an aircraft under part 121.
Further, the AC provides guidance for determining the level of
differences between comparative aircraft when a pair of aircraft have
similar handling or flight characteristics. An applicant may submit
documentation requesting the FAA consider the commonality in that pair
of aircraft be sufficient to allow credits for that commonality, which
may then reduce the amount of duplicative training and checking
requirements and may also reduce, for some aircraft, the recency of
experience required by 14 CFR 121.439 (a). After completion of the
comparative process, if the FAA is convinced that the two aircraft
types share sufficient common characteristics, then the FAA authorizes
qualified flight crews to receive training, checking, and in some
cases, recency of experience credits for that commonality.
Advisory Circular 120-53 standardizes the application process for
applicants and explains the training and checking credits available
when the system differences between related aircraft models are from
Level A through D. For example, a difference that amounts to no more
than a knowledge-based difference that can be addressed in pilot
training by using a computer-based course of instruction (e.g., the B-
757-200 and the B-767-200 hydraulic systems), would be a Level B
difference. On the other hand, a difference that involves full pilot
task training (e.g., visual display and switch position requirements
between the B-767-200 and the B-767-400) would be a Level D difference
necessitating pilot training in a full task training device.
The AC also explains the process for allowing full or partial
credit for recency of experience that may be permitted when aircraft
handling qualities are similar. For example, handling qualities for the
Airbus A-320, A-330, and A-340 aircraft were found to be similar,
therefore credit for recency of experience was allowed.
If an additional series of related aircraft models having similar
handling qualities and commonality of systems is type certificated, the
FAA uses the guidance in AC 120-53 when deciding to allow credit for
training, checking, and recency of experience. When difference levels
between the aircraft models do not exceed Level D, credit is usually
allowed. For example, evaluation of the differences in the flight deck
configuration (e.g., visual displays and switch positions) of the B-
767-400 determined that Level D differences existed between the B-767-
400 and the B-767-200 and B-767-300 series. Therefore, the FAA allows
credit for training and checking for Level A through D differences
between the B-767-200/300 and the B-767-400.
These credits have been provided also within families of aircraft
(same make but different models sharing commonality) with similar
handling qualities and no greater than Level D system differences.
Examples of programs that have taken advantage of these credits are:
``Common Pilot Type Rating'' used by Boeing and ``Cross Crew
Qualification'' (CCQ) used by Airbus.
Proposed Revisions to AC No. 120-53A
In view of the success of the common pilot type rating and CCQ
programs under AC 120-53, proposed AC 120-53A describes the same
process as AC 120-53 for evaluating the differences between comparative
aircraft and determining the training, checking, and recency of
experience requirements based on a commonality determination. Proposed
AC 120-53A restates certain processes to make them more easily
understood and applied by the FAA and industry in view of innovations
and
[[Page 49589]]
advancements in technology and aircraft design that were not envisioned
when AC 120-53 was written.
This proposed AC:
Updates the guidance to reflect the increasing commonality
evolving in contemporary transport category aircraft design.
Streamlines the process, with clearly defined tests, that
permit an applicant to apply for, and the FAA to allow credit for
demonstrating sufficient commonality between aircraft. The process is
updated by incorporating elements of the T2 and T4 tests into the new
T6 test.
Shifts the emphasis from documenting the commonalities to
documenting the differences between aircraft types.
Makes definitional changes. ``Common type rating'' is
replaced by ``Common pilot type rating.'' The term ``variant'' has been
eliminated and its meaning has been consolidated into one term,
``related aircraft.'' It also separates the terms ``Currency'' and
``Recent experience.''
Introduces the term ``Common Takeoff and Landing Credit''
applicable to receiving credit for recency of experience.
Updates the guidance to reflect the increasing commonality evolving
in contemporary transport category aircraft design.
Aircraft manufacturers are now designing more aircraft that share
similar handling and flight characteristics. The use of common flight
deck designs has also become prevalent. These commonalities improve the
safety of aircraft operations and provide an opportunity in the
proposed AC for the FAA to recognize this improvement in safety by
reducing the need for some duplicative training.
Streamlines the process, with clearly defined tests, that permit an
applicant to apply for, and the FAA to allow credit for demonstrating
sufficient commonality between aircraft.
This proposed AC provides a systematic means with clearly defined
tests that permit an applicant to apply for, and the FAA to allow
credit for successfully demonstrating commonality between aircraft. For
example, the T6 test criteria are clearly defined to give applicants
more standardized, specific test criteria than the current T2 and T4
tests. The T6 test requires the applicant to show a commonality within
a specific weight range, center of gravity range and maximum
demonstrated crosswind for takeoff and landing.
Shifts the emphasis from documenting the commonalities to
documenting the differences between aircraft types.
The proposed AC shifts the emphasis from documenting the
commonalities to documenting the differences between aircraft types.
The applicant would continue to show commonalities and the similarities
in handling and flight characteristics by demonstrating the absence of
differences. Where differences do exist, those differences would be
addressed by the appropriate training, checking, and recency of
experience requirements. In the proposed AC the FAA would continue to
allow credit for aircraft shown to have commonality as in AC 120-53.
Makes definitional changes.
``Common type rating'' is replaced by ``Common pilot type rating''
to show a clearer difference between a pilot type rating and a type
certificated aircraft.
The terms ``variant'' and ``related aircraft'' were used
interchangeably in AC 120-53 causing some confusion. The term
``variant'' has been eliminated and its meaning has been consolidated
into one term, ``related aircraft.'' For example, related aircraft
would be two or more aircraft of the same make (Airbus), but not
necessarily under the same type certificate (A-320, A-330 and A-340).
The AC 120-53 definitions of ``currency'' and ``recent experience''
were considered synonymous and used interchangeably. This
interchangeable use ofterms has led to confusion. The proposed revision
separates the terms to eliminate any further confusion.
Introduces the defined term Common Takeoff and Landing Credit
applicable to receiving credit for recency of experience.
A Common Takeoff and Landing Credit (CTLC) allows recency of
experience credit between related aircraft of the same make with
different type certificates that can be demonstrated to have similar
handling and flying characteristics. This credit is applied toward
meeting the requirements of 14 CFR 121.439.
Conclusion
The concept of commonality and the use of credits can reduce
unnecessary training costs while providing an acceptable method of
compliance with the existing regulations. Only the FAA can make a
determination of commonality; and while an applicant may ask the FAA
for a finding of commonality, the FAA will only make such a finding
after the FAA is satisfied that sufficient commonality exists to permit
crediting.
The history of safe operation of the B-757 and B-767 with a common
pilot type rating, and the successful use of similar programs (CCQ)
with other aircraft models by European manufacturers demonstrates that
the FAA can continue to safely allow credit for training, checking, and
recency of experience between aircraft that have demonstrated
commonality. The entire proposed AC is published with this Notice for
the convenience of the reader as Attachment 1.

Attachment 1--Advisory Circular (AC) No. 120-53, Crew Qualification and
Pilot Type Rating Requirements for Transport Category Aircraft Operated
Under 14 CFR Part 121
Advisory Circular
Subject: Crew Qualification and Pilot Type Rating Requirements for
Transport Category Aircraft Operated Under Part 121.
Date: MM/DD/YY.
Initiated by: AFS-200.
[AC No: 120-53A]
This advisory circular (AC) provides an acceptable means, but not
the only means, of compliance with the Code of Federal Aviation
Regulations (CFRs) regarding qualification and type rating of flight
crewmembers operating under Part 121 of the CFRs. Included are criteria
for the determination and approval of training, checking, and currency
necessary for the operation of aircraft. This AC also describes the
process by which the Federal Aviation Administration (FAA) determines
the qualification of the pilot-in-command (PIC) or second-in-command
(SIC) of new or modified aircraft. Details of the systems, processes,
and tests necessary to apply this AC are explained in the appendices.
Provisions of this AC are intended to enhance safety by:
Providing a common method of assessing applicant programs.
Directly relating pilot training and qualification
requirements to fleet characteristics, operating concepts, and pilot
assignments.
Permitting better planning and management of fleets, pilot
assignments, and training resources by outlining what FAA requirements
apply, what training resources or devices are needed, and what
alternatives are possible.
Permitting timely and consistent decisions about fleet
acquisition, integration, modification, or phaseout associated with
pilot qualification or pilot assignments.
[[Page 49590]]
Permitting manufacturers to design aircraft that take
advantage of new technology or their similarity with existing related
aircraft, as appropriate to a particular operator`s fleet.
Encouraging cockpit standardization by crediting commonality
and identifying necessary constraints when differences exist.
Providing a framework for application of suitable credits or
constraints to better address new technology and future safety
enhancements.
1. Focus. This AC addresses aircraft manufacturers or modifiers who
design, test, and certificate aircraft as well as approved 14 CFR part
142 training centers. In addition, it applies to operators whose pilots
operate several related aircraft of the same manufacturer in a mixed
fleet and operators seeking credit for prior pilot experience with
related aircraft of the same manufacturer.
2. Cancellation. AC 120-53, Crew Qualification and Pilot Type
Rating Requirements for Transport Category Aircraft Operated Under CFR
Part 121, Dated May 13, 1991, Is Canceled.
3. Discussion.
a. A System for Pilot Qualification. The FAA specifies
qualification criteria (minimum training, checking, and currency) for
particular aircraft through Flight Standardization Board (FSB)
evaluations and findings. FSB findings are described in reports for
specific aircraft. The reports provide guidance to certificate-holding
district offices (CHDO) for use by principal operations inspectors
(POI) and other inspectors. FSB report provisions serve as a basis for
the FAA to approve operators' programs and for pilot certification.
b. Changing Needs. Necessary support for the FSB process is
provided by the industry. In the past, procedures varied by
manufacturer, individual project, operator, and other factors
including:
(1) Introduction of new and related aircraft and increases in the
significance of modifications to existing aircraft, particularly with
regard to engines or avionics.
(2) Integration of related fleets of aircraft following airline
acquisitions or mergers.
(3) Increased dependence on leased aircraft, many of which are
configured differently than an operator's basic fleet.
(4) A wider variety of equipment options available in new or
retrofit aircraft.
(5) Introduction of new technology in cockpit enhancements.
4. Summary of Revisions. This AC describes necessary revisions and
enhancements to the FSB process to address uniform, systematic, timely,
and comprehensive application of pertinent 14 CFR parts in a changing
and increasingly complex operational environment. This AC revision
deletes master common requirements due to a lack of practical
application. This AC recognizes the concept of reduced differences
between related aircraft and defines the training, checking, currency,
and recency of experience requirements.
a. This AC revision clarifies and introduces new terms and
concepts. These include:
(1) Clarification of the terms ``aircraft type certificate'' and
``related aircraft''.
(2) The difference between currency and recency of experience is
defined.
(3) A definition of ``common pilot type rating'' now including
levels A through D for any aircraft of the same make but of different
aircraft type certificates (TC).
(4) Modified checking requirements to embrace the concept of
checking only at the difference levels between related aircraft.
(5) A new term, ``common takeoff and landing credit'' (CTLC).
(6) An introduction of the T6 test to provide for CTLC (recency of
experience) in mixed fleet flying between separate type-certificated
aircraft with common takeoff and landing characteristics. The intent of
the T6 test is to provide a comparison of aircraft that have not
previously been evaluated for CTLC using the T2 test.
(7) A means to identify and evaluate new technologies that may not
be associated with an aircraft evaluation.
(8) A distinction between supervised line flying (SLF) and
operating experience (OE).
b. Additional concepts are introduced to uniformly apply the 14 CFR
parts applicable to pilot qualification and the differences. The AC's
main concepts are summarized as follows.
(1) Master Difference Requirement (MDR). Master requirements are
expressed in the form of MDRs. MDRs are requirements applicable to
pilot qualification that pertain to differences between related
aircraft. MDRs are specified by the FSB in terms of difference levels.
(2) Difference Levels. Difference levels are formally designated
levels of training methods or devices, checking methods, or currency
methods that satisfy difference requirements between related aircraft.
Difference levels specify FAA requirements proportionate to and
corresponding with increasing differences between related aircraft. A
range of five difference levels in order of increasing requirements,
identified as A through E, are each specified for training, checking,
and currency.
(3) Operator Difference Requirement (ODR). Operators show
compliance with the FAA MDRs through an operator's specific ODR, which
lists each operator`s fleet differences and compliance methods. ODRs
specify requirements uniquely applicable to a particular fleet and
mixed flying situation and are based on the MDRs. ODRs are those
operator-specific requirements necessary to address differences between
a base aircraft and one or more related aircraft, when operating in
mixed fleet flying or seeking credit in transition programs. ODRs
include both a description of differences and a corresponding list of
minimum training, checking, and currency compliance methods that
address pertinent FSB requirements.
Note: These and other concepts are more fully described in the
appendices.
5. Setting FAA Requirements. The FSB process is made up of proposal
development, testing, draft requirement formulation, FSB final
determinations and FAA approval.
a. Applicants' Proposals. Aircraft manufacturers or modifiers
usually initiate proposals for formulation or amendment of FSB
requirements. This is done in conjunction with application for aircraft
type certification or supplemental type certification of an aircraft or
system. The FAA, operators, and, in certain instances, other
organizations or individuals, may initiate proposals or amendments.
b. Standardized Tests. A main element of the requirements
formulation process is the use of standardized testing to determine
pilot qualification requirements. One or more of six tests are applied
depending on the proposal's degree of differences between related
aircraft, difference levels sought, and the outcome of any previous
tests. Only the necessary tests are used. Tests may be waived or
difference levels may be assigned based on operational experience.
c. FAA Formulation and Implementation of Requirements. Following
testing and formulation of draft requirements, FSB requirement
determinations are then made specifying MDRs and any necessary
supporting information. Supporting information may pertain to operator
certification, airmen certification, approval of devices and
simulators, and other items necessary for proper application of MDRs.
FSB reports will be used in the evaluation, certification, and approval
of operators' programs.
[[Page 49591]]
d. Revision of Requirements. FSB reports are periodically updated
when new or modified aircraft are introduced, when requested by an
applicant based on OE, or when the FAA determines it is necessary for
safety reasons.
e. Pilot Type Ratings. A new pilot type rating is typically
assigned when level E training differences are determined between the
candidate aircraft and the base aircraft. The pilot type rating
determination and any training, checking, and currency specifications
established under the testing process of this AC are determined by
evaluating the handling qualities and core pilot skills related to the
candidate aircraft. Systems such as heads-up display (HUD), Enhanced
Vision Systems (EVS), or Synthetic Visions Systems (SVS) may require
Level E training without requiring a new pilot type rating. The FSB,
with the concurrence of the Air Transportation Division, AFS-200, will
make this determination.
f. Common Pilot Type Rating. A common pilot type rating is assigned
when no greater than level D training differences are determined
between aircraft of the same type with different aircraft TCs.
g. Same Pilot Type Rating. A same pilot type rating is assigned
when no greater than level D training differences are determined
between aircraft with the same aircraft TCs (series).
6. Operator Compliance with FAA Requirements.
a. Obtaining FSB Information. Operators are advised of pertinent
FSB information through FAA CHDOs and POIs. Operators may also obtain
FSB information from aircraft manufacturers or modifiers, other
operators, or other aviation organizations that maintain awareness of
FAA policies, and the Web site http://www.opspecs.com.
b. Certificated Operator Compliance with Mixed Fleet Flying. When
aircraft are flown in mixed fleets, certificated operators will comply
with MDRs and other FSB difference provisions. Certificated operators
accomplish this by identifying a base aircraft, describing differences
that exist between their base aircraft and the candidate aircraft, and
by specifying particular means of compliance to satisfy MDRs. Sample
FSB ODRs provide guidance for the approval of an operator's mixed fleet
flying program and specify necessary constraints or permissible
credits. The description of specific differences and compliance methods
are identified in the operator's ODRs. Constraints or credits may
relate to knowledge, skills, devices, simulators, maneuvers, checks,
currency, or any other factors necessary for safe operations.
Constraints or credits may be applied generally or only to specific
aircraft or pilot positions. Once approved, the operator's program must
be conducted in accordance with (IAW) these approved ODRs. ODR
proposals are provided to the FAA CHDO in a standard tabular format and
are approved by POIs only if they meet MDRs and other pertinent FSB
requirements. The operator must apply to amend the ODRs when changes
occur in the base aircraft, comparison aircraft, and/or training
devices that affect the approval basis of the ODRs.
c. Credit between Programs. In addition to mixed fleet flying, ODRs
may be used to permit credit between related aircraft in differences or
transition training and checking programs, consistent with FSB
provisions.
7. FAA Approval of Operator Programs.
a. POI Approval. FAA POIs approve operator programs when those
programs comply with FSB provisions. If less restrictive programs are
proposed, POIs advise the applicant that:
(1) A request for change of the MDRs must be initiated;
(2) The differences between related aircraft must be reduced or
eliminated; or
(3) An alternate approval must be sought.
Note: An example of such a request is an exemption to the
applicable requirement of the training section of the operational
rule under which the operation is conducted.
b. Limitations of POI Authority. When applicable, POIs may
approve programs within provisions of the FSB report and this AC. AC
provisions apply because other general constraints are identified
such as a limitation on the number of different related aircraft
that can be used in mixed fleet flying. POIs shall not approve
programs outside the bounds of FSB or AC provisions without the
authorization of AFS-200. Deviation from FSB or AC provisions will
be approved by AFS-200, only when an equivalent level of safety can
be demonstrated.
8. Application of FSB Requirements to Airmen Certification. The
evaluation items that FSB reports specify include the following:
Knowledge;
Skills;
Abilities;
Maneuvers;
Performance criteria; and
Other relevant items for proficiency checking or other
checks/tests may be identified. This is appropriate to address any
aircraft-specific factors affecting the safe operation of that aircraft
operated under 14 CFR.
9. Training Device and Simulator Approvals.
a. Standard Devices or Simulators. Standardized training methods,
devices, or simulators are associated with each of the training
difference levels. Devices or simulators are approved for particular
operators by their POIs, consistent with National Simulator Program
(NSP) qualification and FSB master requirements.
b. Special Criteria. In some instances, standard device or
simulator criteria may not be appropriate for new technology. The FSB
may specify additional criteria in FSB reports in these instances.
10. Review and Approval. This is a process for review of FSB
evaluations and approval of FSB reports.
11. Appeal of FAA Decisions. The Director, Flight Standards
Service, AFS-1, assigns responsibility to resolve appeals of the FSB
findings.

Appendix 1.--Definitions and References
1. Definitions.
Note: Definitions provided in Appendix 1 apply exclusively to
this advisory circular (AC).
Aircraft Evaluation Group (AEG). FAA organization that sets
training, checking, currency, pilot type rating, Master Minimum
Equipment List (MMEL), and maintenance standards Maintenance Review
Board (MRB) for assigned certificated aircraft types. AEGs also
address operational aspects of aircraft type certification and
resolution of service difficulties.
Applicant. For the purposes of this AC, an applicant may be a
manufacturer, modifier, or operator.
Base Aircraft. An aircraft designated by the applicant used as a
reference to compare differences with another aircraft.
Candidate Aircraft. The aircraft that will be subjected to the
FSB evaluation process outlined in this AC for comparison purposes.
Common Pilot Type Rating. A pilot license endorsement between
separate type-certificated aircraft for the purposes of pilot type
rating that passes the testing criteria of the T1 (equivalence) or
the T2 (handling characteristics) and T3 (core pilot skills with no
greater than level D differences). A common pilot type rating
endorsement is issued after a pilot has received differences
training and checking, where required, on the type-certificated
aircraft for which there is a common pilot type rating designation.
The pilot who is receiving the additional endorsement must be
current and qualified in the base aircraft; since, the check is not
a ``full'' proficiency check as defined by Title 14 of the Code of
Federal Regulations (14 CFR), but an abbreviated differences check
[[Page 49592]]
on the differences from the base to the candidate aircraft. The
differences check, unless it includes the requirements for a
recurrent check, cannot reset the ``recurrent clock'' (a pilot`s
base month for checking purposes).
Common Takeoff and Landing Credit (CTLC). CTLC is a program/
process that allows recency of experience credit between related
aircraft (same make) with different type certificate data sheets
(TCDS) that can be demonstrated to have the same handling and flying
characteristics during the following:
Takeoff and initial climb; and
Approach and landing, including the establishment of
final landing configuration.
Note: The T6 test is used for aircraft that were not tested (T2)
during the initial aircraft evaluation for pilot type rating
designation.
Configuration. Aircraft physical features, which are
distinguishable by pilots, with respect to differences in systems,
cockpit geometry, visual cutoff angles, controls, displays, aircraft
geometry, and/or number of required pilots.
Currency. Currency is the recent experience necessary for the
safe operation of aircraft, equipment, and systems as designated by
the Flight Standardization Board (FSB).
Difference Levels. Difference levels are formally designated
levels of training methods or devices, checking methods, or currency
methods that satisfy differences requirements between related
aircraft. A range of five difference levels in order of increasing
requirements, identified as A through E, are specified for training,
checking, and currency purposes.
Differences Training. Training required before any person may
serve as a required crewmember on an aircraft of a type for which
differences training is included in the certificate holder`s
approved training program.
Differences Check. A partial proficiency check of the
qualification of a pilot at the difference levels between related
aircraft. A differences check can be between series of the same
aircraft type certificate (TC) or between aircraft of separate
aircraft TCs of the same manufacturer.
Flight Characteristics. Flight characteristics are handling
characteristics or performance characteristics perceivable by a
pilot. Flight characteristics relate to the natural aerodynamic
response of an aircraft, particularly as affected by changes in
configuration and/or flight path parameters (e.g., flight control
use, flap extension/retraction, airspeed change, etc.).
Flight Operations Evaluation Board (FOEB). The FOEB is
responsible for preparation and revision of MMELs. The board members
are drawn from the FAA.
Flight Standardization Board (FSB). The FSB is responsible for
specification of minimum training, checking, currency, and pilot
type rating requirements, if necessary, for U.S. certificated civil
aircraft. The board members are drawn from the FAA (AEG,
Headquarters, Flight Standards field offices operations personnel).
Handling Characteristics. The manner in which the aircraft
responds with respect to rate and magnitude of pilot initiated
control inputs to the primary flight control surfaces (e.g.,
ailerons, elevator, rudder, spoilers, cyclic, collective, etc.).
Line Oriented Simulation (LOS). Use of a simulator in place of
the aircraft to reinforce the understanding of differences between
related aircraft. LOS should not be confused with operating
experience (OE), which is required by 14 CFR.
Line Operational Flying (LOF). The LOF phase of the test is used
at the discretion of the FSB during the T3 test to validate the
proposed training and checking. The LOF fully assesses particular
difference areas, examines implications of mixed fleet flying,
assesses special circumstances such as minimum equipment list (MEL)
effects, and evaluates the effects of pilot errors potentially
associated with the differences.
Master Difference Requirements (MDR). MDRs are those
requirements applicable to pilot qualifications that pertains to
differences between related aircraft. MDRs are specified by the FSB
in terms of the minimum difference levels. MDRs form the basis for
an operator to develop their operator differences requirements
(ODR).
Mixed Fleet Flying. Mixed fleet flying is the operation of a
base aircraft and one or more related aircraft for which credit may
be taken for training and/or checking events. The FSB process
defines minimum training and checking difference levels between
related aircraft.
Operational Characteristics. As used with respect to aircraft,
means those features that are distinguishable by limitations, flight
characteristics, normal procedures, nonnormal procedures, alternate
or supplementary procedures, or maneuvers.
Operator Difference Requirements (ODR). If differences exist
within an operator`s fleet that affect pilot knowledge, skills, or
abilities pertinent to systems or procedures, ODR tables provide a
uniform means for operators to comprehensively manage difference
programs and provide a basis for FAA approval of mixed fleet flying.
Pilot Type Rating. A pilot type rating is a ``one time'',
permanent endorsement on a pilot certificate indicating that the
holder of the certificate has completed the appropriate training and
testing required for its issuance as determined by regulation and by
the applicable FSB report. It is recorded by the FAA on the pilot`s
certificate indicating the make, model, and series of aircraft, if
applicable. Title 14 CFR requires a pilot type rating to serve as
pilot-in-command (PIC) and in some cases as second-in-command (SIC)
of U.S. civil large or turbojet aircraft.
Recency of Experience. With respect to flight experience as
required by 14 CFR, means a pilot's completion of the required
number of takeoffs and landings as sole manipulator of the controls
within the preceding 90 days.
Related Aircraft. Related aircraft are any two or more aircraft
of the same make that have been demonstrated and determined to have
commonality to the extent that credit between those aircraft may be
applied for training, checking, or currency, as documented through
MDR and approved by the FSB.
Same Pilot Type Rating. A pilot type rating assigned when no
greater than a level D training difference is determined between
aircraft with the same aircraft TCs (series).
Series. Aircraft sharing the same aircraft type certification
with specific variations that are usually defined by the
manufacturer and usually result in an amended aircraft TC.
Supplementary Procedures. Those procedures that are identified
in the Flight Crew Operation Manual (FCOM) under the section
``Supplementary Procedures'' describing procedures not described
under the ``Normal Procedures'' or ``Nonnormal Procedures''
sections.
Supervised Line Flying (SLF). Supervised experience associated
with the introduction of equipment or procedures requiring post
qualification skill enhancement during which a pilot occupies a
specific pilot position and performs particular assigned duties for
that pilot position under the supervision of a qualified company
instructor or check airman.
Training Footprint. A training footprint is a summary
description of a training program, usually in short tabular form,
showing training subjects, modules, procedures, maneuvers or other
program elements, which are planned for completion during each day
or phase of training.

APPENDIX 2.--PILOT QUALIFICATION AND PILOT RATING REQUIREMENTS
1. Purpose
This appendix provides a comprehensive description of the system
for pilot qualifications outlined in this advisory circular (AC). It
includes definitions, criteria, processes, tests, methods, and
procedures necessary for uniform application of the system.
2. Focus
The appendix applies to and is used by:
a. Aircraft manufacturers or modifiers who design, test, and
certificate Title 14 of the Code of Federal Regulations (14 CFR)
parts 23, 25, 27, and 29 aircraft.
b. Operators who operate under 14 CFR.
c. Operator, manufacturer, or other training centers having
programs approved for use under 14 CFR.
d. Federal Aviation Administration (FAA) offices and inspectors
administering programs under 14 CFR.
3. Introduction
a. A Comprehensive System for Pilot Qualification. This AC and
its appendices provide a systematic means to address requirements
for training, checking, and currency within applicable 14 CFR parts.
Definitions, criteria, processes, procedures, tests, and methods are
consistent with and clarify application of current rules in
particular situations for specific aircraft. This AC provides a
comprehensive system for the FAA and industry to describe, evaluate,
and approve use of particular aircraft and operator programs. The
respective roles of training, checking, currency and airmen
certification are clarified. This includes defining the role and
criteria for designation of pilot type ratings for existing, new, or
modified aircraft. The system is particularly suited to addressing
transition, differences programs, and mixed fleet flying. The system
aids in assuring that pilots attain and maintain the knowledge,
skills, and abilities needed to operate assigned aircraft safely.
b. Master Differences Requirements (MDRs) Set by FAA. The FAA's
Flight Standardization Board (FSB) sets MDRs to address differences
between related aircraft.
c. Specification of Constraints or Credits. The system permits
the specification of constraints or permissible credits. Constraints
or credits may relate to knowledge, skills, abilities, devices,
simulators, maneuvers, checks, currency, or any other such factors
necessary for safe operations. Constraints or credits may apply
generally to aircraft, particular pilot positions, or other
situations or conditions.
d. Recognition of Unique Operator Characteristics. The system
recognizes the unique characteristics of individual operators while
achieving uniformity in application of FAA safety standards. FAA
MDRs determine uniform bounds to tailor individual operator's unique
requirements to a particular fleet and situation. Principal
operations inspectors (POI) approve each operator's unique
requirements within FAA MDRs. Operator unique requirements
accommodate particular combinations of related aircraft flown, pilot
assignment policies, training methods and devices, and other factors
that relate to the application of the FAA MDRs. Accordingly, the
system preserves operator flexibility while standardizing the FAA's
role in review, approval, and monitoring of training, checking, and
currency programs within 14 CFR.
e. Basis for Requirements. The determination of pilot type
rating, minimum differences training, checking and currency
requirements focus on basic operation of aircraft in the National
Airspace System (NAS) under both instrument flight rules (IFRs) and
visual flight rules (VFR). Included are all flight phases from
preflight to shutdown under both normal and nonnormal conditions.
f. Relationship to Other FAA Policies. Although this AC, and the
FSB requirements in some instances, address particular types of
operations or specific aircraft systems (e.g., use of flight
guidance control systems for Category II/III instrument approaches,
long-range navigation, etc.), other ACs address these issues more
thoroughly. This AC and FSB requirements address such issues only to
the extent necessary to assure that pilots are qualified to operate
pertinent systems or equipment as part of initial or continuing
qualification.
4. Concepts
a. An Integrated System for Pilot Qualification.
(1) System Elements. An integrated FAA/applicant system and
process established to determine appropriate requirements, applies
the requirements, and meets those requirements on a continuing
basis, for uniform pilot qualification.
(2) System Overview. The system uniformly applies FAA master
requirements in a way that tailors a particular aircraft to any
operator's unique situation or fleet. The FAA approves unique
operator and fleet requirements for each operator based on FAA
master requirements. The system develops FAA master requirements
based on objective criteria and tests, with applicants' support for
analysis and testing. FSB reports for related aircraft describe FAA
master requirements. MDRs express FAA master requirements. Minimum
acceptable difference levels between related aircraft articulate
MDRs. An operator's training program, checklist, operations manuals,
pilot certification, CTLC programs, and other such approvals are by-
products of compliance with MDRs. Operators comply with MDRs using
unique ODRs, tailored to that operator's programs and approved by
the FAA. ODRs, based on and in compliance with the MDRs, specify
requirements uniquely applicable to a particular operator's mixed
fleet flying situation. An operator's specific document
[[Page 49594]]
describes ODRs by identifying a base aircraft, differences between
related aircraft, and that operator's compliance methods for each
related aircraft. Paragraph 4j describes ODRs. Paragraph 6 describes
ODR preparation and use. Paragraph 7 describes FAA approval of ODRs.
b. MDRs.
(1) MDR Applicability. MDRs are those requirements applicable to
pilot qualification that pertain to differences between related
aircraft. MDRs specify the minimum acceptable difference levels
between related aircraft that may be approved for operators. One
related aircraft is selected by the applicant as a reference for
comparison purposes and is considered a base aircraft. This is
typically the first aircraft on which pilots are qualified, or is
the aircraft of which an operator has the largest number. Difference
levels between the base aircraft and other related aircraft then
specify the minimum difference requirements to be met for pilot
qualification. Major differences in a particular fleet are defined
between groups of related aircraft rather than specifying
differences between each possible configuration and combination of
configurations between related aircraft. MDRs are specified in terms
of training difference levels described in paragraph 4d and are
shown on an MDR table.
(2) MDR Content. MDRs specify the minimum training, checking,
and currency acceptable to the FAA for pilot qualification regarding
differences.
(3) MDR Formulation, Description, and Revision. MDRs are
formulated by the FAA FSB for each related aircraft. MDRs are
originally specified when an aircraft is first type certificated.
MDRs are formulated using standardized tests and evaluations in
conjunction with the type certification or supplemental type
certification process. MDRs are based on an applicant's (usually an
aircraft manufacturer) proposal, FAA evaluation of that proposal,
OE, and test results when tests are necessary. FSB determinations
also consider operator recommendations, safety history, and other
relevant information. MDRs are described in provisions of an FSB
report and may be revised if necessary. MDRs are revised when
aircraft are developed or modified, tests or OE shows a need for
revision, a revision is requested by an applicant and evidence
indicates the need for revision, or rules or FAA policies change.
MDRs are revised by a process similar to that used for initial
formulation of requirements.
(4) MDR Use. MDRs are applied to specific operators through
formally described ODRs that are developed by and tailored to each
operator. FAA field offices use the MDRs as the basis for approval
of individual operator's differences programs for approval of
initial or transition programs where credit for previous training or
experience with other related aircraft is sought.
(5) The MDR Table. An example of typical MDRs for the B-737-200,
-300, -400, -500, -600, -700, -800, and -900 is shown in Figure 1.
MDR table requirements are shown for each pair of aircraft by
notations in each element of corresponding columns and rows of the
table. Each element of the table identifies the minimum differences
training, checking, and currency requirements applicable to mixed
fleet flying. The MDR table identifies a pertinent base aircraft and
particular aircraft for which requirements are sought. Note the
minimum difference levels that correspond to the pertinent column
and row, and special requirements in footnotes, if applicable.
(6) Use of Higher or Lower Difference Levels. Operators must
satisfy difference requirements by using the methods acceptable for
the specified level or a higher level. Lower level methods may be
used in addition to the required levels but may not substitute for
the required level or be used exclusively instead of the required
level.
[[Page 49595]]
[GRAPHIC] [TIFF OMITTED] TN28AU07.001
(7) Differences Within a Series. Differences may exist even
within series shown on an MDR table, such as within the A-318/319/
320/321 series. MDR elements may show requirements from one series
to another identified in the footnotes. Such requirements, however,
apply only if pertinent differences exist between those aircraft.
(8) More Than Two Related Aircraft. When pilot assignments apply
to more than two related aircraft, such as the A-320, A-330, and A-
340, each pertinent requirement of the MDR table applies.
Applications of multiple requirements for flying two or more related
aircraft and certain limits to flying large numbers of related
aircraft are described in paragraph 7k.
(9) Special Requirements.
(10) MDR Footnotes. Footnotes can be used to credit, constrain,
or set alternate levels when special situations apply. Use of
footnotes permits accommodation of variations in installed
equipment, options, pilot knowledge or experience on other aircraft,
training methods or devices, or other factors that are not addressed
by basic levels between aircraft. For example, a footnote may allow
credit or apply constraints to the use of a particular flight
guidance control system (FGCS), flight management system (FMS), or
electronic flight instrument system (EFIS), which is installed on
aircraft. Footnotes are an appropriate means to address requirements
that relate to specific systems (e.g., flight director and FMS)
rather than a particular aircraft. In such instances, generic
knowledge or experience with the particular system may be readily
transferable between related aircraft. Footnotes may also be used to
set different requirements for initial training or checking rather
than for recurrent training or checking. When necessary, footnotes
are fully described in the body of the FSB report.
(a) Other Limitations. Other limitations may occasionally be
identified within a difference level (e.g., C*/C*/C). The asterisk
following the difference level in such instances identifies a
special requirement or limitation pertaining to a particular
training method or device. Such notes typically relate to acceptable
training device characteristics when the simulator evaluation and
approval process or standard criteria of this AC are not available
to address a particular situation appropriately.
(11) MDRs for Aircraft With the Same or Common Pilot Type
Ratings. A single FSB report and MDR table may apply to aircraft
that are assigned the same pilot type rating (same aircraft TC). For
example, a single MDR table may cover the A-318/319/320/321 that
have a same pilot type rating. A single FSB report and MDR table may
also apply to aircraft that are assigned a common pilot type rating.
For example, a single MDR table may cover both the B-767 and B-757
that have a common pilot type rating. When level E training is
required for an aircraft with the same aircraft TC and an additional
pilot type rating is assigned, such as the B-747 and B-
[[Page 49596]]
747-400, a single MDR table for all series of a type-certificated
aircraft still applies.
(12) Minimum acceptable difference levels are assigned based on
standard tests described in Appendix 3.
c. Difference Levels.
(1) General Description. Difference levels are formally
designated levels of training methods or devices, checking methods,
or means of maintaining currency that satisfy minimum difference
requirements or pilot type rating requirements. Difference levels
specify FAA requirements proportionate to and corresponding with
increasing differences between related aircraft. A range of five
difference levels in order of increasing requirements, identified as
A through E, are each specified for training, checking, and
currency. MDRs are specified in terms of difference levels.
Difference levels are used to credit knowledge, skills, and
abilities applicable to an aircraft for which a pilot is already
qualified and current, during initial, transition or upgrade
training for other related aircraft. Operators, who conduct mixed
fleet flying where credit is sought, should apply difference levels
and address all mixed fleet flying requirements to ensure compliance
with FAA requirements necessary to assure safe operations.
(2) Basis for Levels. Difference levels apply when a difference
with potential to affect fight safety exists between related
aircraft. Differences may also affect knowledge, skills, or
abilities required of a pilot. If no differences exist or if
differences exist but do not affect knowledge, skills, abilities or
flight safety, then difference levels are not assigned or applicable
to pilot qualification. When difference levels A through E apply,
each difference level is based on a scale of differences in design
features, systems, or maneuvers. In assessing the effects of
differences, both flight characteristics and procedures are
considered, since flight characteristics address handling qualities
and performance, while procedures include normal and abnormal/
nonnormal/emergency items.
(3) Relationship Between Training, Checking, and Currency
Levels. While particular aircraft are often assigned the same level
(e.g., C/C/C) for training, checking, and currency, such assignment
is not necessary. Levels may be assigned independently. For example,
an aircraft may be assigned level C for training, level D for
checking, and level C for currency (e.g., C/D/C).
(4) Designation of a Pilot Type Rating. Candidate aircraft
having the same TC are assigned the same pilot type rating if
training differences are not greater than level D. Candidate
aircraft having different TCs that have training differences no
greater than level D may be assigned a common pilot type rating. A
candidate aircraft is assigned a different pilot type rating when
difference training level E is required. When different pilot type
ratings are assigned because of one or more candidates requiring
level E training, pilot type ratings may be assigned to related
aircraft consistent with a logical grouping of the most similarly
related aircraft.
d. Training Difference Levels.
(1) Level A Training. Level A difference training is that
differences training between related aircraft that can adequately be
addressed through self-instruction. Level A training represents a
knowledge requirement that, once appropriate information is
provided, understanding and compliance can be assumed. Level A
compliance is achieved by such methods as issuance of operating
manual page revisions, dissemination of operating bulletins, or
differences handouts to describe minor differences in aircraft.
Level A training is limited to the following situations:
(a) A change that introduces a different version of a system/
component for which the pilot has already shown the ability to
understand and use (e.g., an updated version of an engine).
(b) A change that results in minor or no procedural changes and
does not adversely affect safety if the information is not reviewed
or forgotten (e.g., a different vibration damping engine mount is
installed, expect more vibration in descent; logo lights are
installed, use is optional).
(c) Information that highlights a difference, which is evident
to the pilot, inherently obvious, and easily accommodated (e.g.,
different location of a communication radio panel, a different
exhaust gas temperature limit that is placarded, or changes to
nonnormal ``read and do'' procedures).
(2) Level B Training. Level B difference training is applicable
to aircraft with system or procedure differences that can adequately
be addressed through aided instruction. At level B, aided
instruction is appropriate to ensure pilot understanding, emphasize
issues, provide a standardized method of presenting material, or aid
retention of material following training. Level B aided instruction
can utilize slide/tape presentations, computer based tutorial
instruction, stand-up lectures or video tapes. Situations not
covered under the provisions of level A training may require level B
(or higher levels) if certain tests described in later paragraphs
fail.
(3) Level C Training. Level C differences training can only be
accomplished through use of devices that are capable of systems
training. Level C differences training is applicable to related
aircraft having part task differences that affect skills or
abilities and knowledge. Training objectives focus on mastering
individual systems, procedures, or tasks, as opposed to performing
highly integrated flight operations and maneuvers in ``real time.''
Level C may require self-instruction or aided instruction, but
cannot be adequately addressed by a knowledge requirement alone.
Training devices are required to supplement instruction, ensure
attainment or retention of pilot skills and abilities, and
accomplish the more complex tasks, usually related to operation of
particular aircraft systems. While level C systems knowledge or
skills relate to specific rather than fully integrated tasks,
performance of steps to accomplish normal, nonnormal, alternate,
recall procedures, or maneuvers related to particular systems (e.g.,
flight guidance control systems/flight management systems) may be
necessary. Typically, the minimum acceptable training media for
level C training would be interactive computer-based training,
cockpit systems simulators, cockpit procedure trainers or part task
trainers (e.g., FMS or traffic collision avoidance system (TCAS)).
(4) Level D Training. Level D training can only be accomplished
with devices capable of performing flight maneuvers and addressing
full task differences of knowledge, skills, and/or abilities.
Devices capable of flight maneuvers address full task performance in
a dynamic real time environment. The devices enable integration of
knowledge, skills, and abilities in a simulated flight environment,
involving combinations of operationally oriented tasks and realistic
task loading for each relevant phase of flight. Level D training,
knowledge, and skills to complete necessary normal, nonnormal,
alternate, or recall procedures are fully addressed for each related
aircraft. Level D differences training requires mastery of
interrelated skills that cannot be adequately addressed by separate
acquisition of a series of knowledge areas or skills that are
interrelated. The differences are not so significant that a full
transition training course is required. If demonstrating
interrelationships between the systems is important, use of a series
of separate devices for systems training will not suffice. Training
for level D differences requires a training device that has
accurate, high fidelity integration of systems and controls, and
realistic instrument indications. Level D training may also require
maneuvers, visual cues, motion cues, dynamics, control loading or
specific environmental conditions. Weather phenomenon such as low
visibility, CAT III, or windshear may or may not be incorporated.
Where simplified or generic characteristics of an aircraft type are
used in devices to satisfy difference level D training, significant
negative training must not occur as a result of the simplification.
Typically, the minimum acceptable training media for level D
training would be flight training device level 6.
(5) Level E Training. Level E training is applicable to
candidate aircraft having such significant full task differences
that require a ``high fidelity'' environment to attain or maintain
knowledge, skills, or abilities. Training at level E can only be
satisfied by the use of a simulator qualified at level C or D
consistent with FAA criteria. Level E training, if done in an
aircraft, should be modified for safety reasons where maneuvers can
result in a high degree of risk (i.e., an engine set at idle thrust
to simulate an engine failure). As with other levels, when level E
training is assigned, suitable credit or constraints may be applied
for knowledge, skills, and/or abilities related to other pertinent
related aircraft. Credits or constraints are specified for the
subjects, procedures, or maneuvers shown in FSB reports and are
applied through the ODR table.
Note: Training differences levels specified by the FSB represent
minimum requirements. Operators may use a device associated with a
higher difference level to satisfy a training differences
requirement. For example, if level C differences are assessed due to
installation of a different FMS, operators may train pilots using
the FMS installed in a full flight simulator (FFS) as a system
trainer if a
[[Page 49597]]
dedicated part task FMS training device is not available.
e. Checking Difference Levels.
(1) Initial and Recurrent Checking. Difference checking
addresses any pertinent pilot testing or certification that includes
pilot type rating checks, proficiency checks, Advanced Qualification
Program (AQP) evaluations, and any other checks specified by FSB
reports. Initial and recurrent checking levels are the same unless
otherwise specified by the FSB. In certain instances, it may be
possible to satisfactorily accomplish recurrent checking objectives
in devices that do not meet initial checking requirements. In such
instances, the FSB may recommend certain devices that do not meet
initial check requirements for use to administer recurring checks.
The POI/Training Center Program Manager, in coordination with the
FSB, may require checking in the initial level device when doubt
exists regarding pilot competency or program adequacy.
(2) Level A Checking. Level A checking indicates that no check
related to differences is required at the time of differences
training. A pilot is responsible for knowledge of each related
aircraft flown. Differences items should be included as an integral
part of subsequent recurring proficiency checks.
(3) Level B Checking. Level B checking indicates that a ``task''
or ``systems'' check is required following transition and recurring
differences training. Level B checking typically applies to
particular tasks or systems such as FMS, TCAS, or other individual
systems or related groups of systems.
(4) Level C Checking. Level C checking requires a partial
proficiency check using a device suitable for meeting level C (or
higher) differences training requirements following transition and
recurrent differences training. The partial check is conducted
relative to particular maneuvers or systems designated by the FSB.
Example of a level C check: Evaluation of a sequence of maneuvers
demonstrating a pilot's ability to use a FGCS or FMS. An acceptable
scenario would include each relevant phase of flight that uses the
FGCS or FMS.
(5) Level D Checking. Level D checking requires a partial
proficiency check for one or more related aircraft following both
transition and recurrent training. The partial proficiency check
covers the particular maneuvers, systems, or devices designated by
the FSB. Level D checks are performed using scenarios representing a
``real time'' flight environment and devices permitted for level D
differences training. A full proficiency check is typically
conducted on the base aircraft, and a partial proficiency check on
the related aircraft, covering all pertinent differences.
(6) Level E Checking. Unless specified, level E checking
requires that a full proficiency check be conducted in a level C or
D FFS. As with other levels, when level E checking is assigned,
suitable credit or constraints may be applied for knowledge, skills,
and/or abilities related to other pertinent related aircraft.
Credits or constraints are specified for the subjects, procedures,
or maneuvers shown in FSB reports and are applied through the ODR
table.
Note: Assignment of level E checking requirements alone does not
result in assignment of a separate pilot type rating. Only the
assignment of level E training requirements may result in assignment
of a separate pilot type rating.
f. Currency Difference Levels. The term ``currency'' as used in
this AC addresses recent experience necessary for safe operation of
aircraft as designated by the FSB. Currency issues not specified by
the FSB are covered by regulation.
(1) Level A Currency. Level A currency is considered common to
each related aircraft. Thus, assessment or tracking of currency for
separate related aircraft is not necessary or applicable.
Maintenance of currency in any one related aircraft or a combination
of related aircraft will suffice for any other related aircraft.
(2) Level B Currency. Level B currency is ``knowledge related''
currency, typically achieved through self-review by individual
pilots for a particular aircraft. Self-review is usually
accomplished by review of material provided by the operator to
pilot. Such currency may be undertaken at an individual pilot`s
initiative; however, the operator must identify the material and the
frequency or other situations in which the material should be
reviewed. Self-review may be based on manual information, bulletins,
aircraft placards, memos, class handouts, videotapes, or other
memory aids that describe the differences, procedures, maneuvers, or
limits for the pertinent aircraft that pilots are flying. Examples
of acceptable compliance with level B currency are:
(a) The issuance of a bulletin that directs pilots to review
specific operating manual information before flying a related
aircraft. Level B currency may be regained by review of pertinent
information to include bulletins, if that related aircraft has not
been flown within a specified period (e.g., fly that related
aircraft or have completed a review of the differences in
limitations and procedures within a specified number of days).
(b) Pilot certification on a dispatch release that they have
reviewed pertinent information for a particular related aircraft to
be flown on that trip. Level B currency cannot, however, be achieved
solely by review of class notes taken by and at the initiative of an
individual pilot unless the adequacy of those notes is verified by
the operator.
(3) Level C Currency. Level C currency is applicable to one or
more designated systems or procedures, and relates to both skill and
knowledge requirements. An example would be establishment of FMS
currency, flight guidance control system currency, or other
particular currency that is necessary for safe operation of a
related aircraft. Establishment of level C for a related aircraft
with an FMS would typically require a pilot to fly that related
aircraft within the specified period of time or re-establish
currency. Currency constraints for level C are established by the
FSB. When level C currency applies, pertinent level B currency must
also be addressed. Examples of methods acceptable for addressing
level C currency are:
(a) Pilot scheduling practices resulting in a pilot being
scheduled to fly a related aircraft with the pertinent system/
procedure within the specified period of time;
(b) Tracking of an individual pilot's flying of related aircraft
to ensure that the particular system/procedure has been flown within
the specified period of time;
(c) Use of a higher level method (level D or E currency); or
(d) Other methods as designated or found acceptable by the FSB.
(4) Re-establishing Level C Currency. When currency is lost,
currency may be re-established by completing required items using a
device equal to or higher than that specified for level C
differences training and checking. Other means to re-establish
currency include flights with an appropriately qualified check
airman/instructor, completion of proficiency training, or a
proficiency check. In some instances, a formal refamiliarization
period in the actual aircraft with the applicable system operating
while on the ground may be acceptable if permitted by the FSB. Such
refamiliarization periods are completed using an operator-
established procedure under the supervision of a pilot designated by
the operator. In the case of a noncurrent SIC, a designated pilot-
in-command (PIC) may be authorized to accompany a pilot to re-
establish currency.
(5) Level D Currency. Level D currency is related to designated
maneuvers, and addresses knowledge and skills required for
performing aircraft control tasks in real time, with integrated use
of associated systems and procedures. Level D currency may also
address certain differences in flight characteristics including
performance of any required maneuvers and related normal/abnormal/
emergency procedures for a particular related aircraft. A typical
application of level D currency is to specify selected maneuvers,
such as takeoff, departure, arrival, approach, or landing, which are
to be performed using a particular FGCS and instrument display
system. Either a pilot must fly a related aircraft equipped with the
FGCS and particular display system sufficiently often to retain
familiarity and competence within the specified currency period, or
currency must be re-established. Currency constraints for level D
are established by the FSB. When level D currency applies, pertinent
level B and level C currency must also be addressed. Examples of
methods acceptable for addressing level D currency are:
(a) Tracking of flights by a particular pilot in a particular
related aircraft to assure experience within the specified currency
period.
(b) Tracking the completion of specific maneuvers based on
logbook entries, Aircraft Communication Addressing and Reporting
System (ACARS) data, or other reliable records to assure experience
within the specified currency period.
(c) Scheduling of aircraft or pilots to permit currency
requirements to be met with verification that each pilot has
actually accomplished the assigned or an equivalent schedule.
(d) Completion of pilot certification, proficiency check,
proficiency training, AQP evaluations, or other pertinent events in
[[Page 49598]]
which designated maneuvers are performed in a device or simulator
acceptable for level D currency.
(e) Use of a higher level method (level E currency).
(f) Other methods as designated or found acceptable by the FSB.
(6) Re-establishing Level D Currency. When currency is lost,
currency may be re-established by completing pertinent maneuvers
using a device equal to or higher than that specified for level D
differences training and checking. Other means to re-establish
currency include flight with an appropriately qualified check airman
during training or in line operations, completion of proficiency
training, a proficiency check, or AQP proficiency evaluation.
(7) Level E Currency. Level E currency may specify system,
procedure, or maneuver currency item(s) necessary for safe
operations, as identified by the FSB, to be accomplished in a Level
C/D simulator for that related aircraft. FSB provisions related to
takeoff and landing are applied in a way that addresses needed
system or maneuver experience. For example, if FGCS, FMS, EFIS,
navigation, or other system or maneuver experience is the basis for
a currency requirement, approval of an operator's program at level E
includes the use of those systems in conjunction with satisfying
takeoff and landing requirements. In this instance, making three
simulator takeoffs and landings in VFR closed traffic without using
the FGCS, EFIS, or FMS may not be sufficient to meet level E
currency requirements.
Note: Assignment of level E currency requirements does not
result in assignment of a separate pilot type rating. Only the
assignment of level E training requirements may result in assignment
of a separate pilot type rating.
(8) Re-establishing Level E Currency. When currency is lost,
currency may be re-established by completing pertinent maneuvers
using a device specified for level E differences training and
checking. Other means to re-establish currency include flight with
an appropriately qualified check airman during training or in line
operations, completion of proficiency training, a proficiency check,
or AQP evaluation.
(9) Competency Regarding Abnormal/Nonnormal/Emergency
Procedures. Competency for nonnormal maneuvers or procedures is
generally addressed by checking requirements; however, in particular
abnormal/nonnormal/emergency maneuvers or procedures may not be
mandatory for checking or training. In this situation, it may be
necessary to periodically practice or demonstrate those maneuvers or
procedures even though it is not necessary to complete them during
each check. In such instances, the FSB may specify a currency
requirement for training or checking applicable to abnormal/
nonnormal/emergency maneuvers or procedures that are to be
performed. This is to assure that extended periods of time do not
elapse in a series of repeated training and checking events in which
significant maneuvers or procedures may never be accomplished. When
an abnormal/nonnormal/emergency maneuver or procedure is not
mandatory and is not accomplished during each proficiency training
or proficiency check, but is still important to occasionally
practice or demonstrate, the FSB may establish a currency
requirement. When designated by the FSB, these currency requirements
identify each abnormal/nonnormal/ emergency maneuver or procedure,
the currency level applicable, and an applicable time period or any
other necessary/appropriate constraints.
(10) Difference Level Summary. Difference levels are summarized
in Figure 2 below for training, checking, and currency. Complete
descriptions of difference levels for training, checking and
currency are given above.

g. Operating Experience (OE) for Aircraft.
(1) Application of OE. Requirements for OE are consistent with
provisions for OE specified under 14 CFR.
(2) Credits or Constraints. OE must meet the applicable
requirements of the CFR part under which operations are conducted,
except that credit for applicable OE in other related aircraft may
be permitted. When approved by the FAA, OE associated with
differences may be accomplished as part of or in conjunction with
line oriented simulation (LOS).
h. Supervised Line Flying (SLF). Experience associated with the
introduction of equipment or procedures requiring post qualification
skill enhancement during which a pilot occupies a specific pilot
position and performs particular assigned duties for that pilot
position under the supervision of a pilot instructor or check airman
qualified for the operator. One or more of the reasons described
below may apply:
(1) Introduction of new systems (e.g., Local Area Augmentation
System (LAAS), Automatic Dependent Surveillance Broadcast (ADS-B),
runway area advisory system (RAAS), etc).
(2) Introduction of new operations (e.g., oceanic operations,
Extended-Range Operations with Two-Engine Airplanes (ETOPS)).
(3) Experience for a particular pilot position (e.g., PIC, SIC).
(4) Special characteristics (e.g., effects of unique airports,
mountainous areas, unusual weather, special air traffic control
procedures, or nonstandard runway surfaces) on this aircraft.
i. Recency of Experience. Credit towards the recency of
experience requirements of 14 CFR may be permitted for takeoffs and
landings performed in related aircraft as provided by CTLC. CTLC
must be validated through the FSB process and must be carried out in
accordance with (IAW) the operator's CTLC approved program.
j. Operator Difference Requirements (ODR).
(1) ODR Purpose. If differences exist within an operator's
fleet, which affect pilot knowledge, skills, or abilities pertinent
to systems or procedures, ODR tables provide a uniform means for
operators to comprehensively manage difference programs and provide
a basis for FAA approval of mixed fleet flying.
(2) ODR Content. ODRs identify a base aircraft, describe
differences between aircraft, and show an operator's methods of
compliance with FAA requirements. The FAA approves an operator's
initial ODR and each subsequent revision for the following:
(a) Base Aircraft. ODRs identify an aircraft or group of
aircraft (aircraft of the same series with minor configuration
differences) within an operator's fleet as a base aircraft. The base
aircraft serves as a reference for comparison with candidate
aircraft. Selection criteria and characteristics of base aircraft
are described in paragraphs 6c and 7c.
(b) Candidate/Related Aircraft. ODRs identify particular
aircraft flown by an operator within each fleet. ODRs consider only
those aircraft and combinations of aircraft actually flown by that
operator. ODRs describe differences within an operator's fleet
between the base aircraft and other related aircraft.
(c) Significance of Differences. Differences are described in
summary form and are
[[Page 49599]]
categorized by differences in design features, systems, and
maneuvers. Differences are evaluated relative to their effect on
either flight characteristics, pilot skills, and/or procedures.
Procedures consider normal, nonnormal, alternate, and recall items.
Limitations are considered in conjunction with normal procedures.
(d) Compliance Methods. ODRs show how each operator's program
addresses differences, through description of training, checking, or
currency methods for each fleet. ODRs describe the specific or
unique constraints or credits applicable, and any precautions
necessary to address differences between aircraft. ODRs must comply
with and be just as or more restrictive than FAA MDRs and other FSB
provisions. Constraints or credits may be applied to all aircraft in
a fleet or only to certain aircraft. Constraints or credits may
address training devices, simulators, checking and currency methods,
knowledge, skills, procedure maneuvers, or any other factors that
apply to or are necessary for safe operations. Training, checking,
and currency compliance methods are proposed and revised by each
operator consistent with ODR examples from a variety of sources that
are acceptable to the FAA. ODR examples are found in FSB reports.
(3) Standard ODR Format. ODRs are depicted in tables in
summarized form. If necessary, any explanation of details about
differences, constraints and credits, precautions or compliance
methods are included in attachments or appendices to ODR tables or
are cross referenced to other operator documents. Figure 3 shows the
general format for ODR tables, including examples of design,
systems, and maneuver differences. The far-left column lists design,
system, or maneuver differences that are pertinent. The ``Remarks''
column summarizes specific areas or items of difference. The
``Flight Characteristics'' and ``Procedural Change'' columns
identify what (if any) difference effects are noted. The
``Compliance Methods'' section of the table notes the particular
operator's approved means of compliance with FAA MDR provisions. The
following abbreviations apply:
ACFT--Aircraft.
AFDS--Auto Flight Display System.
AVT--Audio Visual Tapes.
CBT--Computer Based Training.
EFIS--Electronic Flight Instrument System.
EICAS--Engine Indicating and Crew Alerting System.
FBS--Fixed Base Simulator.
FFS--Full Flight Simulator.
FLT CHAR--Flight Characteristics.
FMC--Flight Management Computer.
FMS--Flight Management System.
PROC CHNG--Procedural Changes.
SU--Stand Up Instruction.

(4) ODR Approval, Distribution, and Availability. ODRs are
approved for each fleet by an operator's FAA POI in accordance with
FSB report provisions. ODRs must be prepared, reviewed, approved and
then used to govern training before start of operations. The
operator retains approved ODRs with a duplicate copy as part of FAA
certificate-holding district office (CHDO) records.
[[Page 49606]]
(5) ODR Revision. ODR tables are revised by operators and re-
approved by the FAA when fleet characteristics change or when
compliance methods change. Fleet characteristic changes include
redesignation of base aircraft, modification of aircraft, addition
of aircraft, change of aircraft, or phaseout of aircraft. Changes in
compliance methods refer to introduction of new or different
training methods, contracting for use of different devices or
simulators, revision of checking or currency methods, or other such
changes. Revisions to ODRs are also prepared, reviewed, and approved
before operating.
Note: Paragraph 6 describes the development, approval, and
application of ODR tables to individual operators' programs.
Paragraph 7 describes FAA review and approval of programs by POIs.
5. Formulation of FSB Reports, MDRS, and Designation of Pilot Type
Ratings
a. Requirements Formulation Process Overview. The process for
FAA formulation and revision of training, checking, currency, and
pilot type rating requirements is shown in Figure 4.
(1) The process determines which information is required for an
aircraft; it includes a proposal for requirements, tests, and
evaluations of the proposed requirements; it then finalizes,
applies, and implements the FSB requirements. Applicants propose
MDRs, examples of ODRs, and any other FSB provisions that are
necessary. Proposals for requirements are based on design
objectives, analysis, evaluation of OE, other programs that have
been proved acceptable to the FAA, or other methods. Setting of
requirements is based on an objective set of tests and standards,
analysis of results, and FAA judgments considering OE. The applicant
and the FAA prepare and conduct standardized tests. The applicant
provides test support, and the FSB conducts the evaluation. The FSB,
in conjunction with the applicant, evaluates the results, and the
FAA formulates proposed minimum requirements. The FSB sets final
requirements by specifying MDRs and other FSB provisions. An FSB
report that describes findings is disseminated to FAA field offices
and posted on the operations specifications (OpSpecs) Web site for
application to specific operators' programs. The formulation and
application process of FSB requirements starts at the time a new
aircraft is proposed to the FAA and continues throughout the fleet
life of that aircraft. For aircraft already in service the process
may be initiated when significant modifications are proposed, a new
piece of equipment (e.g., a HUD) requiring operational evaluation is
introduced and requested by operators, or when mixed fleet flying
takes place. The FAA addresses periodic revisions of requirements
when necessary, and revisions are initiated by the FAA and
applicants as needed.
b. Proposals for MDRs, Example ODRs, and Special Requirements.
(1) When Proposals Are Necessary. The FAA usually determines
when proposals are necessary and advises the applicant what
information is needed, in conjunction with aircraft type
certification or supplemental certification programs. Necessary
information may include MDRs for related aircraft or other elements
of the FSB reports. The applicant considers existing MDRs and
existing or proposed ODRs.
(2) Proposal Formulation. The formulation of a proposal
typically starts when a manufacturer proposes a new design or design
modification. The applicant will then do the following:
(a) Formulate necessary information for training, checking, and
currency for the aircraft in proposals for MDRs and example ODRs.
(b) Prepare example ODR tables for candidate aircraft to support
development of a proposed MDR. These examples represent proposals
for programs for those specific aircraft and configurations that the
FAA could approve.
(c) Identify related aircraft for the proposed MDR table.
(d) Formulate any necessary tests to assess difference levels
and associated training, checking, and currency requirements for
incorporation in the MDR table.
(e) Identify interpretations of possible test results. The FAA
and the applicant will then reach an agreement on specific tests,
devices, and schedules to be used for the test program.
(f) The applicant submits proposals for the following items to
the FAA, as necessary:
MDRs
Example ODRs
Tests and criteria to be used
Other supporting information associated with training,
checking, or currency programs
c. Difference Level Tests. A sequence of five standard tests,
described in Appendix 3, is used to set MDRs, minimum acceptable
training programs, other FSB provisions, and define pilot type
rating requirements. One or more of these tests are applied
depending on the difference level sought, and the success of any
previous tests used in identifying MDRs. Only those tests needed are
used to establish minimum requirements. The outcome of these tests,
and any resulting difference levels that apply, establish minimum
requirements for training, checking, currency, and pilot type
ratings. The FAA will establish an additional pilot type rating if
it is determined during this testing that the assignment of a level
E differences training is required.
Note: One additional test, the T6 test, can be used to establish
CTLC between related aircraft, when not previously demonstrated in a
T2 test.
(1) Steps in the Testing Process. The typical steps of the
testing process are as follows:
(a) The applicant develops representative training programs,
difference programs, and necessary supporting information, as
needed.
(b) The applicant identifies proposed MDRs and example ODRs.
(c) The applicant proposes and the FAA determines which tests
and criteria apply.
(d) The applicant proposes and the FAA determines which
aircraft, simulation devices, or analyses are needed to support
testing.
(e) The applicant makes a proposal to the FAA, and agreement is
reached on test procedures, schedules, and specific interpretation
of possible results.
(f) Tests are conducted and results evaluated.
(g) The FSB draft minimum requirements are formulated.
Note: If the candidate aircraft is anticipated to have no
greater than level A or B differences with the base aircraft and a
same or common pilot type rating is the proposed assignment, then
the FSB may elect to directly apply a T1 test for equivalency.
(2) Test Purpose and Application. A summary of the purpose and
application of each of the six difference tests is shown in Figure
5.
(3) Test Relationships and Applications. The test process
relationships, the sequence of conducting tests when more than one
test is needed, and application of test outcomes are shown in Figure
6. The start of the process is shown at the top of Figure 6.
Resulting difference levels are at the bottom. New aircraft, for
which a new aircraft TC is sought, follow the testing path at the
right of the diagram for a T5 test. At the end of the process the
aircraft is assigned a new pilot type rating. For candidate aircraft
seeking a same or common pilot type rating the test process follows
a path at the left of Figure 6. A series of decisions or tests leads
to assignment of one or more levels A through D and in some
instances may lead to level E. If level E is assigned as a result of
this path, then a separate pilot type rating is assigned. This
process is followed whenever a new aircraft is proposed, when
significant changes are proposed, or when revisions to existing
requirements are needed as a result of requests for change or OE.
(4) Test Failures and Retesting. Generally, failures do not have
paths back to lower levels. T3 test failure at level C can lead to
subsequent passage at C (after modification of the system,
operational procedures, or training and retesting) or D. Similarly,
failure at level D can subsequently lead to either D (after
modification of the system, operational procedures, or training and
retesting) or E, but not C. Failure at level E can only lead to
retesting with increased programs, improved programs, or improved
devices since there is no higher level. T5 failure paths do not lead
back to level C or level D. However, subsequent new programs do not
preclude making a proposal at a lower differences level if
technology changes, aircraft redesign takes place, training methods
significantly change, or device characteristics and effectiveness
change.
(5) Same and Common Pilot Type Rating Tests. Aircraft seeking
same or common pilot type rating will follow the path in Figure 6
from the top left of Figure 6 through T1 or T2 and T3 tests
resulting in the assignment of level A, B, C, or D differences.
(6) ``Currency'' Tests. Currency tests T4 are not shown in
Figure 6 because they are necessary only when the applicant seeks
relief from system, procedural, and maneuver currency requirements
set by the FSB.
(7) Detailed Test Specifications. A detailed specification for
the evaluation process and tests to establish difference levels are
described in Appendix 3.
[[Page 49607]]
d. FSB Assessments and Proposal Formulation. The FSB assesses
the applicant's proposals, test results, analysis, and any other
relevant factors to formulate a draft FSB report, which includes
MDRs and other pertinent training, checking, currency requirements.
The FSB either validates the applicant's proposed MDRs, training
programs, and other information, or generates alternate
requirements, which may include more stringent requirements,
additional training, additional testing, etc.

e. Comments Solicited. The FSB proposal is circulated with
interested parties representing the manufacturer, operators, and
other pertinent FAA organizations such as engineering, flight test,
pilots' associations, and other aviation representatives for
comment, relevant information, and recommendations.
f. FSB Final Determinations and Findings.
(1) FSB Determinations. Any comments submitted to the FAA are
reconciled, and final FSB determinations are made. Specification of
MDRs, example ODRs, acceptable training programs, and other FSB
provisions are completed. Any necessary pilot testing or currency
provisions are identified. Assignment of any necessary pilot type
rating(s) is made.
[[Page 49611]]
(2) Basis for FSB Judgments. FSB judgments are based on review
of the applicant`s supporting documentation, proposed ODR tables,
test results, and any other pertinent information, such as FAA
policies, OE, and results of other similar FSB evaluations.
Specifically, FSB report provisions are based on the following:
(a) Appropriate Data, Evaluation, or Tests. Testing may include
aircraft demonstration, simulation tests, device testing, or
analysis.
(b) Direct Experience. The industry may have substantial
experience with successful operational programs, which can be useful
in the assignment of minimum difference level requirements. This
experience may include particular training devices, training/
checking/currency requirements, and mixed fleet flying.
(c) Indirect Experience. Applicable experience with foreign
operators, military programs, or other programs that can establish
the suitability of training, checking, or currency standards may be
permitted as a means for FSBs to set MDR or ODR levels.
(d) Applicant and Industry. FSB requirements are set following
solicitation and review of comments.
(3) Device or Simulator Characteristics. Minimum characteristics
for devices or simulators for training, checking, or currency are
noted using standard training device or simulator definitions. When
standard criteria for methods, devices, or simulators are not
appropriate for an aircraft, the FSB identifies suitable criteria to
be applied and coordinates with the FAA National Simulator
Evaluation Team (NSET). Standard devices and simulators applicable
to each difference level are shown in Figure 7.

g. FSB Report Preparation Distribution and FAA Application.
(1) Report Preparation and Approval. After MDRs are finalized,
the FSB report is prepared and approved. Sufficient background or
explanatory material is provided in the report to permit FAA
personnel to properly administer FSB provisions.
(2) FSB Report Distribution. The FSB report is posted on the
OpSpecs Web site for implementation in approval of particular
operators` programs. The FAA technical requirements described in FSB
reports are primarily intended for the operators use to develop
programs that will be approved by the FAA.
(3) FSB Report Implementation. FSB requirements,
recommendations, and guidance are provided to FAA field offices
through FSB reports for each aircraft. These reports are directives
to FAA offices to identify acceptable methods of applying pertinent
14 CFR parts to each specific operator. FSB provisions set
acceptable standards by which FAA inspectors approve, review,
correct, or limit individual operator`s programs. The FSB report is
the basis for approval of training, checking, and currency programs
approved by each FAA office. The report is also the basis for pilot
certification by FAA or operators and the surveillance of operators`
programs. POIs may approve individual operator`s programs that meet
or exceed master requirements, but they cannot approve programs that
are less than master requirements. Aviation safety inspectors (ASI),
aircrew program managers (APM), aircrew program designees (APD), and
designated pilot examiners (DPE) use the report as the basis for
administration of oral examinations, simulator checks, flight
checks, proficiency checks, and OE. Preparation and application of
ODRs by operators is described in paragraph 6. Review and approval
of ODRs by FAA POIs is covered in paragraph 7.
h. FSB Report Revision.
(1) General FSB Revision Process. A general revision process is
established to update determinations and findings contained in FSB
reports. Revisions may be needed annually for active fleets with
numerous change requests. Revisions may be needed infrequently for
aircraft not undergoing significant change.
(2) Revisions for New Aircraft. When an applicant proposes to
develop or add a series of a type-certificated aircraft, MDRs and
other FSB provisions must be revised to address that series. If an
applicant initiates this action, the procedures noted in paragraph 5
regarding initial determination of minimum training, checking,
currency, and pilot type rating requirements are followed. If an
operator proposes to add an aircraft that is not covered within an
existing FSB report (e.g., a foreign manufactured aircraft) POIs
should consult with the pertinent Aircraft Evaluation Group (AEG).
An FSB will determine the best method of addressing the development
of the necessary FSB report. This is particularly important for
older aircraft fleets in which differences may be significant, but
manufacturer support is no longer available and aircraft imported
into the United States that have been used only by foreign
operators.
(3) Revision for Aircraft Modified by Operators. When an
aircraft is to be modified by an operator, the POI must determine if
the change affects MDRs, example ODRs, or other FSB report
provisions. The criteria for this assessment includes whether or not
the difference affects pilot knowledge, skills, or abilities
pertinent to flight safety. If a change meets the criteria, the
operator should supply the POI with a difference description and
analysis of the effects of the difference. The POI makes a
preliminary estimate of the difference levels then advises the
applicable AEG/FSB. The AEG/FSB may concur with the POI`s assessment
or require other action. If FSB action is required, the AEG will
initiate that action through the FSB chairman. The FSB may require
that additional information or analysis be provided or that the
entire test process or parts thereof be applied. The AEG may
authorize the POI to approve assignment of the difference level.
Changes to the MDRs will be made through the normal FSB revision
process.
6. Operator's Application of FSB Provisions, Preparation, Use, and
Revision of ODRS
a. General.
(1) Process Overview. FSB reports contain MDRs and other
provisions that are applied by FAA offices in approving operators'
programs. MDRs are applied through a particular method that
identifies specific ODRs and compliance methods. Application of MDRs
and other FSB provisions are one means to ensure pilot qualification
for safe operations. This is necessary so that regardless of which
aircraft is flown, uniform training, checking, and currency
standards are met within the constraints of 14 CFR. Paragraph 6
describes operator application of MDRs and other FSB provisions for
training, checking, and currency. This is done through operator
preparation and FAA approval of ODRs for each operator. When
aircraft are used in mixed fleet flying, this AC's provisions and
FSB provisions comprehensively address differences in training,
checking, and currency requirements for each aircraft. In some
instances, the FAA may limit the number of different aircraft
permitted in mixed flying. ODRs are used to identify credits or
[[Page 49612]]
constraints between aircraft. These credits may also be applied to a
related aircraft when transitioning to another related aircraft when
those aircraft are intended for use in mixed or nonmixed fleet
operation. The overall process for operator application of MDRs and
development, approval, use, and revision of ODRs is shown in Figure
8.
(2) Availability and Use of FSB Information. FSB requirements
are made available to operators through FAA CHDOs, applicant,
industry trade associations, posted on the OpSpecs Web site, or
other sources. When preparing initial or difference programs for
specific fleets, individual operators apply the requirements of the
applicable FSB report.
b. Application of MDRs and Preparation and Use of ODRs.
(1) Need for ODRs. When operating a mixed fleet, operators
prepare the necessary ODR table proposals to describe their
particular fleet and show compliance methods. This is done to assess
effects of differences, plan compliance methods, and obtain POI
approval for that operator`s specific program. ODR tables must be
prepared and approved by the FAA for each fleet in which FSB
requirements are established IAW FSB provisions.
(2) Operator Responsibilities. The operator's responsibilities
include:
(a) Specification of a base aircraft.
(b) Identification of differences between the aircraft within a
mixed fleet.
(c) Preparation of proposed ODR tables.
(d) Assessment and description of the effects of the differences
on training, checking, and currency.
(e) Proposal of training, checking, and currency methods
consistent with MDRs and FSB provisions.
(f) Presentation of proposed ODR tables with necessary
supporting information to the FAA POI for approval.
(g) Revision of ODR tables when aircraft are introduced,
modified, phased out, devices change, or MDRs change.
(3) Use of Standard ODR Format. A common format for ODR tables
is used to facilitate preparation, review, use, comparison with
MDRs, and ensure consistency of application and approval by POIs.
The common format is used in all cases where ODR tables are required
except when only a few minor differences exist and level A applies.
In this event, letters between an operator and FAA containing the
necessary information and approval may suffice if acceptable to the
POI.
(4) Minimum Threshold for ODR Preparation. Within the mixed
fleet, a minimum threshold for preparation of ODR tables occurs when
there are differences that potentially affect knowledge, skills, or
abilities necessary for flight safety. Differences not related to
this criterion need not be addressed in ODR tables.
(5) ODR Description and Examples. ODRs are described in
paragraph 4. Examples of acceptable ODR tables for a particular
type-certificated aircraft are shown in each FSB report.
(a) Systems Shown on the ODR Table of Figure 3. An example of
several pages from an ODR table is shown in Figure 3. Figure 3 shows
the application of ODRs to address systems differences and
compliance methods. In Figure 3 differences are grouped in the order
associated with a typical operations manual. Air Transport
Association (ATA) code numbers are shown for cross-reference. The
``Remarks'' column depicts differences and the ``Flight
Characteristics'' and ``Procedural Change'' columns address effects
of differences.
(b) Maneuvers Shown on the ODR Table of Figure 3. The
``Remarks'' column depicts differences. The ``Flight
Characteristics'' and ``Procedural Change'' columns address effects
of differences. The reference ``SEE APP'' refers you to an appendix
to the table, which the operator prepares to more fully list and
explain the particular procedural changes that pertain to the
maneuver in the ``Procedural Change'' column.
(6) Other Use of ODRs. The ODR process may be used for other
applications such as flight attendant or dispatcher qualification
tracking, but such use is not required as part of this AC's
provisions.
c. Selecting Base Aircraft. An operator chooses a base aircraft
from one of the aircraft operated. Base aircraft are defined in
Appendix 1. Additional information regarding base aircraft selection
is in paragraph 7.
d. Identification of Differences and the Analysis of Effects of
Those Differences. Differences must be described between base
aircraft and other related aircraft. This may be done from base to
each other related aircraft. Differences may also be described from
any related aircraft to each other related aircraft. All MDR
requirements must be satisfied relative to the base aircraft so the
pairing of aircraft not authorized to be flown in a mixed fleet
environment by the FSB reports is avoided. As long as a complete and
clear relationship can be drawn from the base aircraft to each other
related aircraft and all MDR requirements are met from the base
aircraft, to each other related aircraft, there is no need to
describe each possible combination of aircraft. This permits a
comprehensive identification of differences that exist in the fleet,
determines the effects of those differences, and shows compliance
methods. Differences are generally organized to follow an operations
manual or flight manual to facilitate use and review, and should be
categorized by design, systems, and maneuvers. Effects of
differences are stated in terms of effects on flight characteristics
and procedures. Procedures include normal, nonnormal, alternate, and
recall procedures, as applicable. Since complete descriptions may be
too lengthy for direct incorporation in ODR tables, appendices, or
references to other operators' documents may be used to describe
differences or effects. Some differences or effects may be repeated
in the analysis. For example, an FMS difference may be noted in both
a navigation system section and maneuver section associated with
preflight setup. The objective is to assure each difference that
pertains to pilot training, checking, or currency is identified and
addressed, so it is not necessary to limit difference descriptions
to prevent overlap.
e. Identification of Compliance Methods. Once differences and
difference effects are described, methods of comprehensively
addressing each difference (compliance methods) are shown. With the
difference descriptions, redundancy may occur. The same training or
checking compliance item shown for one item may also be associated
with and credited for other items. The objective for description of
compliance methods is to show that each difference is addressed in
some appropriate way, to show that the method and level chosen is
consistent with the FSB MDRs, and example ODRs at a level at least
equal to that required by the MDRs.
f. When Proposed ODR Compliance Methods Do Not Meet MDRs. If
proposed ODR compliance methods do not satisfy MDRs or other FSB
report constraints, the following alternatives exist:
(1) Differences may be reduced or eliminated by modification of
aircraft, systems, or procedures.
(2) Other training methods or devices that fully comply with
MDRs and other FSB provisions may be acquired, leased, or otherwise
applied.
(3) Pilot assignments may be separated for a fleet so that mixed
flying of related aircraft does not occur.
(4) MDR change proposals may be requested through FAA POIs to
the FSB. If FSB authorized changes to the MDRs are made, the
operator may then apply the revised criteria.
g. Maximum Number of Related Aircraft. Comparative differences
between related aircraft may comply with FSB provisions; other
limitations may also constrain mixed fleet flying. To prevent
cumulative effects of differences for multiple related aircraft from
adversely affecting pilot performance, the FAA sets guidelines for
the maximum number of related aircraft to be flown. At difference
level A, the number of related aircraft is greater since differences
are fewer and less significant, whereas at level D or level E the
number of related aircraft that can be flown is fewer because the
differences are greater. To accommodate an increase in the
differences level, increasing limitations are placed on the number
of related aircraft that may be flown at the higher levels.
Paragraph 7k contains specific guidance to POIs for approval of
multiple related aircraft.
h. Application, Review and Approval. Paragraph 7 describes the
FAA review and approval process. The process is summarized here to
facilitate ODR table preparation. An operator submits the proposed
ODR tables and necessary supporting information to the POI to apply
for differences program approval. The supporting information may
include any appendices to the ODR tables necessary for evaluation of
the proposal, a transition plan if needed, and a proposed schedule
for implementation. POIs may also require review of such pertinent
and additional information as copies of bulletins, manuals, or other
training materials, before they approve proposed ODRs. If devices
are proposed that are not approved by the POI, or evaluated by the
NSET, a review and approval of those training devices may be
necessary before ODR approval. Sufficient lead-time must be provided
to the FAA for review. Lead-time depends on such factors as
[[Page 49613]]
the complexity of program, proposed difference levels, number of
related aircraft, other operator precedents already set, and FAA
experience with the proposed aircraft, training devices, and
methods. Many noncontroversial level A changes can be reviewed and
approved in a few days. Complex programs with many related aircraft
can require months for review and approval. It is the operator's
responsibility to consult with the POI to ensure that sufficient
lead-time is provided to review initial submissions or changes. At
least 60 days notice is acceptable for most programs. After the
operator submits the program proposal, POIs compare the proposed ODR
with the FSB report provisions including the MDRs. POIs consult
pertinent FAA policy directives (Handbook, notices, Safety Alerts
for Operators (SAFO), etc.) for interpretations or guidance in
accomplishing the review. In certain instances the POI must consult
with the FSB before ODR approval. If ODRs are consistent with FAA
policies and within the constraints of the MDRs and example ODRs,
the POI will approve the operator's ODR tables and its proposed
differences program. When approved by the FAA, ODRs establish the
basis for training, checking, and currency programs for a given
fleet for that operator.
i. Implementation Provisions Transition Period. In certain
instances, a transitional period, agreed upon by the POI with FSB
concurrence, may be necessary to permit operators to continue
operations under previously approved programs until they are able to
comply with FSB requirements. This is necessary when FSB provisions
are initially set or revised and provisions require lead-time for
program preparation, device acquisition, or to revise previously
approved programs. Paragraph 7m and the individual FSB reports for
each type-certificated aircraft discuss FAA approval of transition
provisions.
j. ODR Revision. ODR revisions are initiated when changes occur
in an operator`s fleet relating to differences, difference effects,
or compliance methods. ODR revisions are appropriate when such
changes affect pilot knowledge, skills, or abilities relevant to
flight safety. Examples of program changes or factors that may
require ODR revision include:
(1) Addition or deletion of aircraft in a fleet;
(2) Modification of base aircraft or comparison aircraft in a
fleet;
(3) Change of base aircraft;
(4) Discontinuation of use, addition of new or modification of
training devices referenced by ODRs;
(5) Revision of training methods with a resulting change in
compliance levels;
(6) Changes in effects of differences such as revised
procedures, performance, or flight characteristics;
(7) FAA revision of MDRs or other FSB provisions;
(8) Adverse OE or training and checking experience that dictates
inadequacy of ODRs, MDRs, or other FSB provisions;
(9) FAA surveillance results, enforcement actions, or failure of
an operator to comply with provisions of their approved ODRs; and
(10) Other factors as determined by the POI.
Note: Revisions to ODRs are approved using the same procedures
as for initial ODR's approval.

7. FAA Review and Approval of Operator Programs
a. General.
(1) FAA Responsibilities. FAA has the responsibility for review,
approval, and continuing surveillance of individual operator
programs consistent with this AC and FSB provisions. Within a CHDO,
POIs have the responsibility for program review and approval. In
addition to review, approval, and continuing surveillance of
operator programs, CHDO and other district offices manage pilot
certification consistent with the criteria of this AC and FSB
provisions.
(2) Approval Basis. FAA approvals are based on FSB report
findings and policy guidance included in FAA directives (e.g., Order
8400.10, Air Transportation Operations Inspector Handbook, notices,
SAFOs, etc.). Except as provided for in transition plans, all
preparations must be complete and provisions approved before
conducting training, checking, or establishing currency under this
AC and an FSB report.
b. Operator Application of ODRs.
(1) Operators Using Related Aircraft in Mixed fleet Flying. If
FSB requirements are published, operators operating aircraft in
mixed fleet flying must apply provisions of this AC and the FSB
report. AC criteria and FSB MDRs must be applied anytime pilots
operate mixed fleets between training and checking events.
(2) Threshold Requiring ODR Preparation. Even though an operator
has different configurations of aircraft used in mixed fleet flying,
there is some threshold below which ODR tables and POI approval is
not required. The threshold requiring AC and ODR application occurs
when differences in related aircraft affect pilot knowledge, skills,
and/or abilities pertinent to flight safety. If systems, controls,
indications, procedures, or maneuvers are different and these
differences have an effect that significantly relates to what the
pilots needs to know or do for safe mixed fleet flight operation,
then an operator must prepare ODR tables and seek FAA approval.
Conversely, ODR tables would not need to be prepared in situations
that do not affect flight safety. In such instances ODR tables are
not needed even though pilots routinely operate several related
aircraft. A minimum threshold is set to preclude unnecessary
administrative assessment of mixed fleet flying, which has no safety
implications. If changes to the fleet do not affect pilot knowledge,
skills, or abilities affecting flight safety, then such changes need
not be considered in addressing FSB or this AC provision.
[[Page 49615]]
(3) FAA Review of ODR Proposals. After preparation the carrier
submits proposed ODR tables and supporting information to the CHDO
and POI for review and approval. POIs evaluate the following:
(a) The operator has made an appropriate identification of a
base aircraft.
(b) Operators have comprehensively identified differences in the
particular fleet. This includes appropriate ODR table comparisons
between the base aircraft and each related aircraft.
(c) The operator`s assessment of the affects of differences on
flight characteristics and procedures for the base aircraft and each
related aircraft are suitable and valid.
(d) The compliance methods listed are consistent with the
requirements of the MDR tables, footnotes, other pertinent FSB
report provisions, FAA Order 8400.10, and associated advisory
materials.
(e) ODR provisions adequately address any ``subtle differences''
between related aircraft that have a possibility of inducing
potentially serious pilot errors.
(f) Training materials, methods, devices, and simulators
proposed are acceptable, approved by the NSET if necessary, or if
FSB provisions apply, the ODR tables meet FSB constraints.
(g) ASIs, APMs, and APDs are prepared to apply FSB report
checking standards.
(h) Implementation plans are adequate and consistent with FSB
provisions and other FAA policy.
(i) Other factors determined necessary by the POI are considered
and any requirements met.
(4) The POI uses the example ODR tables and the MDRs provided in
the FSB report as a basis for evaluating the suitability of a
particular operator`s proposed ODR table. The MDR always remains the
primary basis for comparison. The AEG should be consulted in the
absence of conclusive guidance in making such judgments. Guidance
for evaluation of specific system or maneuver items may be found by
comparison of the proposal with the example ODR table shown in the
FSB report and other approved ODR tables. The operator may use
devices, techniques, or methods of an equal or higher difference
level. Critical methods must be at least at the level specified by
the FSB on the MDRs and shown in the example ODR table. Actual ODR
tables proposed by the operator may show a variety of compliance
methods to satisfy a particular item, ranging from level A through
the level required by the MDRs. For example, if the MDR requirement
is a minimum of level C, the operator may propose to use a
combination of level A bulletins, level B slide tape presentations,
and level C training devices to satisfy pertinent items. However, at
least level C must be shown for critical items. The operator may
choose to satisfy a level C MDR provision with level D or level E
methods.
(5) ODR Review Example. The following is an example of the
process for review of a specific item on a proposed ODR table. For
each proposed ODR item both the FSB example ODR table and MDRs are
consulted and compared with the operator`s proposal. If the MDRs
specify that level C devices are needed for training, checking, and
currency between the base aircraft and a related aircraft and the
example ODR table shows applicable level C systems differences or
maneuvers, then the POI should ensure that the proposed ODR table
submitted also shows at least level C for those pertinent systems or
maneuvers.
c. Base and Other Aircraft Identification.
(1) Selecting the Base Aircraft. Base aircraft are defined in
Appendix 1. In general, base aircraft are used as reference for
comparison of differences that affect, or could affect, pilot
knowledge, skills, or abilities pertinent to flight safety. A base
aircraft should typically be the aircraft that the operator trains
to first, the aircraft that the operator has the largest number of,
the aircraft most pilots fly frequently, or the aircraft that
represents a configuration that the operator eventually will have as
a standard. Another aircraft may be selected as a base aircraft when
the previous base aircraft is being phased out, converted to a new
configuration, or other such factors. A base aircraft may be
redesignated at the discretion of the operator with FAA concurrence.
A base aircraft is identified by make, type-certificated aircraft,
model, and series or other distinguishing classifications.
Classification should distinguish pertinent differences in
configuration, handling characteristics, performance, procedures,
limitations, controls, instruments, indicators, systems, installed
equipment, options, or modifications.
(2) Identifying Related Aircraft. A related aircraft is an
aircraft or a group of aircraft with the same characteristics that
have pertinent differences from a base aircraft. Pertinent
differences are those that require different or additional pilot
knowledge, skills, and/or abilities that affect flight safety.
Differences considered pertinent are those relating to
configuration, handling characteristics, performance, procedures,
limitations, controls, instruments, indicators, systems, installed
equipment, options, or modifications. Related aircraft can exist
between different models, series or within a model/series. When
designated in FSB reports, any aircraft included in a MDR table is
considered a related aircraft. Like base aircraft, operators
designate related aircraft by one of the following:
(a) Model/series.
(b) FAA registration ``N number''.
(c) Operator tail number.
(d) Any other classification that can uniquely distinguish
pertinent differences between each related aircraft group and a base
aircraft.
(3) Accounting for Each Related Aircraft. The important factor
in base and related aircraft identification and ODR table
preparation is that regardless of the combination used, there should
be direct and complete traceability of both differences and
compliance methods. There must be a clear description showing the
adequacy of compliance methods to assure proper training, checking,
and currency to safely operate each aircraft assigned.
d. Approval of ODRs.
(1) Approval Method. Following review and determination that an
operator`s program meets pertinent FSB requirements, the POI
approves that particular program by signing ODRs. ODR tables are
approved for each applicable related aircraft. Signature of ODRs or
revisions, together with other relevant documents such as training
programs and OpSpecs, constitute approval by the POI of that
operator's differences training, checking, and currency program
requirements. ODR tables are used for most programs. In instances
where aircraft have only a few minor differences at level A,
approval may take the form of a letter including necessary
information in lieu of using tables.
(2) POI Authority at level A and B. POIs have authority at A and
B level to make determinations without AEG coordination if
compliance methods are within the MDRs. This is important to provide
timely response to minor differences requests. The results of these
determinations are forwarded to the pertinent FSB for permanent
retention, comparison, and future FSB evaluation.
(3) POI Coordination Required at Level C and Above. At C, D, and
E level the POIs may approve operator programs only if the programs
are clearly within the requirements of the MDRs. If there is doubt
whether or not an operator's program meets the MDRs, the POI
consults with the FSB well before the operator's program approval
date, to allow time for review and resolution of open issues. If the
operator request is unclear or less strict than the MDRs
requirements, the POI may not approve that program.
(4) Initial and Final Approval. Like other training programs,
POIs may authorize ``initial'' approval for an assessment period to
review program effectiveness. Final approval should be made after
suitable experience is obtained (generally within 6 months) IAW
criteria in FAA Order 8400.10. In situations where initial approval
is completed but final approval is delayed because of continuous
revision or that results are uncertain should be avoided. When
operators propose to add aircraft, modify existing aircraft, change
base aircraft, phase aircraft out, or take other actions, which make
the applicability of ODRs unclear, then the ODR tables for that
operator must be updated. For some operators a continuous series of
ODR table modifications will occur as its fleet changes.
Nevertheless, the ODR tables must be current at all times. ODR
tables are used as a primary means for establishing regulatory
compliance and managing surveillance of training, checking, and
currency programs.
e. POI Uncertainty Regarding Program Compliance. The POI must
resolve any questions before approval if it is not clear that the
operator's proposal complies with the MDR table and other FSB
provisions. When issues cannot be resolved to clearly establish
compliance with MDRs or other FSB report provisions, the AEG/FSB
should be consulted. Early in program development, POIs may need
more consultation with FSB members. In mature programs, better
examples will be available in FSB reports, other operator ODR, and
the manufacturer`s larger databases for operators.
f. Proposals that do not Comply with FSB Provisions. If the
operator proposes a program less restrictive than the requirements
of the MDRs or other FSB
[[Page 49616]]
provisions, then options of paragraph 6h. apply. If an operator
wishes to pursue a proposal less restrictive than the FSB report or
MDRs, details of the proposal and supporting documentation should be
presented to the POI for forwarding to the AEG/FSB. The POI will
evaluate the carrier`s proposal and, if justified, forward the
proposal with recommendations for revision of MDRs.
g. FSB Revision of MDRs or Other FSB Provisions. When requested
by a POI, the FSB reviews an operator`s proposals and if necessary
modifies MDRs and other FSB provisions. If master requirements have
been amended and the proposal meets the revised requirement, the POI
may approve the proposal. Other operators can also apply for similar
approval or reductions based on the revised FSB report. Major
changes in the MDR table may require review by the full FSB. The FSB
may consider minor changes or interpretations on an ad hoc basis
between FSB meetings for that aircraft. For some requests changes
can be made based on existing or the supplied information. Complex
cases may require testing to be conducted by the applicant before
the MDR table is changed. Should the MDRs be updated to accommodate
a change request, the proposed ODR can be approved within the new
MDRs. Proposals for revisions to levels C, D, or E must be forwarded
to the FSB for resolution through the formal FSB process. Allow at
least 60 days for FAA evaluation of such proposals.
h. Proving Tests. When a related aircraft with difference levels
C or greater is introduced by an applicant, proving runs may be
needed. Proving runs are usually needed for levels D and E. At level
E, regulatory provisions for proving runs must be met. Training
flights, test flights, delivery flights, and demonstration flights
may be credited toward levels C and D proving requirements if
necessary operational experiences are demonstrated and the flights
are IAW an FAA-approved plan. FAA Order 8400.10 describes policies
for FAA approval of proving tests.
i. Line-Oriented Flight Training (LOFT), LOS, or SLF. When
operators have LOFT/LOS/SLF programs and additional related aircraft
are approved, the POI must review those LOFT/LOS/SLF programs to
assure applicability to each related aircraft. SLF in the aircraft,
or in some instances simulator (as determined by the FSB), may be
necessary IAW provisions of the FSB report and with the approval of
the POI.
j. OE. As described in this AC and FSB reports, OE is consistent
with definitions and requirements of 14 CFR. OE credit, as provided
by the FSB for experience with related aircraft, may be permitted
with the approval of the POI.
k. Limitations on the Total Number of Related Aircraft.
(1) Mixed Flying of Multiple Related Aircraft. When mixed fleet
flying involves pilots operating more than a base aircraft and a
single additional related aircraft, additional constraints limiting
the total number of aircraft may apply. Operation of multiple
related aircraft requires a review by the POI to ensure that pilots
can retain and properly apply necessary differences information or
skills for each related aircraft without confusion. When more than
two related aircraft are flown, POIs must specifically ensure that
subtle or compounded differences between the various related
aircraft do not result in confusion of procedures, maneuvers, or
limitations. ODRs proposed for the overall combination of aircraft
to be flown must be examined to ensure the following:
(a) That multiple differences do not result in confusion of
requirements or an excessive level of complexity for pilots to
adjust to or retain important differences information;
(b) That subtle variations in differences information are not
mistakenly applied and lead to unsafe conditions; and
(c) That the amount of differences information is not excessive,
not applied to the wrong aircraft, or not forgotten.
l. Compliance Checklist for CHDOs. FSB reports provide a CFR
compliance checklist. The checklist identifies those 14 CFR parts,
ACs, or other FAA requirements that are in compliance. Pertinent 14
CFR items not shown on the checklist or items shown but not reviewed
by the AEG/FSB for compliance must be reviewed by the CHDO before
POI approval of OpSpecs permitting those aircraft to be used under
14 CFR. Items found not compliant by the AEG/FSB must be reconciled
and compliance established before operation. The compliance
checklist is an aid to CHDOs used to show the status of those 14 CFR
items evaluated by the AEG/FSB, but does not comprehensively address
all possible 14 CFR items and ACs that an operator may need to
demonstrate compliance. OpSpecs, exemptions, deviations, or other
factors, which the AEG/FSB may not be aware of, may also apply and
may modify compliance status or methods shown in the checklist.
m. Implementation of FSB Provisions. These provisions are
addressed in each type-certificated aircraft FSB report and must
comply with any criteria shown in that report. POIs approve
implementation provisions at the same time ODR tables or revisions
are approved. Operators that do not elect to apply this AC or
implement FSB provisions specified by the FSB report require
approval by the Director, Flight Standards Service, AFS-1.
n. Aircraft That Do Not Have an FSB Report. When an FSB report
is not prepared for a given type-certificated aircraft, or when MDRs
or other provisions are not shown, programs are approved IAW the 14
CFR, Order 8400.10, and other pertinent inspector guidance material.
8. Application of Requirements to Airmen Certification
a. General. In addition to master requirements, the FSB report
contains specifications for administration of pilot type rating or
proficiency checks by FAA inspectors or operator check airmen. FAA
pilot certification inspectors, APMs, operator check airmen, APDs,
and DPEs should be familiar with FSB provisions regarding the proper
administration of any necessary checks or evaluations for type-
certificated aircraft or their series covered by the FSB report.
b. Checking Specifications. FAA pilot certification inspectors
and APMs should assure proper application and administration of
checks required by FSB reports as constrained by the MDR and
specific ODR tables. FSB reports describe difference levels which
constrain the various maneuvers, procedures, or unique factors to be
considered by inspectors or check airmen when administering checks
or observing OE. For example, certain nonnormal procedures may be
required and others may be waived (for example no flap landings).
Other unique procedures or maneuvers particular to an type-
certificated aircraft may be necessary. Any unique configurations or
failure conditions that should be observed while administering
checks are described.
c. Checks Regarding Complex Systems.
(1) Partial proficiency checking is required for differences
associated with systems that are determined to be at or greater than
level C.
(2) Complex systems checks include hands-on operation and ensure
demonstrated procedural proficiency in each applicable mode or
function. Specific items and flight phases to be checked are
specified (e.g., initialization, takeoff, departure, cruise,
arrival, approach, and pertinent nonnormals). The FSB may require
additional training beyond that which is otherwise required by 14
CFR to qualify in each type-certificated aircraft. This training may
be in the form of LOFT, LOS, or SLF.
9. Training Device and Simulator Approval
a. Training Device and Simulator Characteristics.
(1) Minimum Device and Simulator Characteristics. AC 120-40 and
AC 120-45 describe minimum acceptable characteristics and standards
for flight training devices and simulators. The FSB directly applies
these standards in difference level specifications. When applicable,
the FSB specifies other device characteristics as the minimum
acceptable for differences training, checking, or currency between
certain related aircraft. The FSB reports identifies these
characteristics.
(2) Coordination with the FAA National Simulator Program (NSP).
When the FSB specifies device characteristics, the FSB coordinates
with the NSET to ensure simulator criteria compatibility and
approval process definition. If device or simulator characteristics
have not been previously recognized by the FAA as meeting the
provisions of this AC, FSB, or the simulator evaluation and approval
process, they must be evaluated by the NSET in consultation with the
FSB before use in an approved program.
b. Aircraft/Simulator/Device Compatibility.
(1) Devices and Simulators to Match Aircraft. When pilots fly
related aircraft in a mixed fleet, the combination of simulators and
training devices used must satisfy MDR and ODR provisions specific
to the aircraft flown by that operator. The POI, FSB, and the NSP
must address the acceptability of differences between training
devices, simulators, and aircraft operated as appropriate. The FSB,
POI, and when necessary, the Air Transportation Division,
[[Page 49617]]
AFS-200, or the General Aviation and Commercial Division, AFS-800,
as applicable, identify acceptable credit for simulators and
training devices.
(2) Differences Between Devices, Simulators, and Aircraft. When
differences exist between related aircraft and the proposed training
devices, or simulators to be used, then MDRs and ODRs may be used as
guidance for acceptance and approval as is done between aircraft.
The FSB, the NSP, and AFS-200 or AFS-800, as applicable, should be
consulted when uncertainty exists regarding the use of MDRs and ODRs
for acceptance or approval of these devices. The FSB will not
recommend use or approval of devices that differ significantly from
the actual operated aircraft.
c. Simulator and Device Approvals.
(1) NSP Representation to the FSB. An NSP member may serve as an
advisor to the FSB or a member of the FSB, to address designation of
and approval processes for devices and simulators at C, D, and E
difference levels.
(2) Coordination of NSP Criteria with the FSB. National
simulator team development of criteria for training devices and
approval test guides for new aircraft are coordinated with the FSB.
This ensures compatibility of FSB/NSP requirements and effective use
of resources for development of approval test guides and
determination of FSB requirements.
10. Review and Approval
FSB reports are approved as designated by AFS-1. In the event
that revision of an FSB report is necessary, the FSB is provided
with necessary policy guidance to implement applicable changes.
11. Appeal of FAA Decisions
When there is disagreement with provisions of an FSB report,
that disagreement may be expressed to the FSB chairman for the
pertinent type-certificated aircraft. If an issue cannot be
resolved, the issue may then be addressed to AFS-200. Additional
information, data, or analysis may be provided to support differing
views regarding the FSB provisions in question.

APPENDIX 3.--RATING AND LEVEL TESTS--PLANNING AND APPLICATION
1. Preparation
a. The pilot type rating, difference level definition, and test
process are initiated when an applicant presents an aircraft for
type certification. If the applicant presents a candidate aircraft
to the Flight Standardization Board (FSB) as a new aircraft type
certification with no anticipated application for pilot type rating
credit for similarities with aircraft previously type certificated,
then the FSB analyzes the training program requirements using test
T5. The results of T5 will determine a separate pilot type rating
and the minimum required training, checking, and currency standards
as applicable to that type-certificated aircraft. If the applicant
presents an aircraft seeking pilot training, checking, or currency
credit, based on similarities with an aircraft previously type
certificated, a series of possible tests (T1/T2/T3) are developed
and used to determine its level of difference with the base aircraft
of comparison. The results of these tests will determine whether the
aircraft pilot type rating is a common pilot type rating between
separate type-certificated aircraft; or the same pilot type rating
of same type-certificated aircraft. The level of differences will
determine the minimum required training, checking, and currency
standards as applicable to the candidate aircraft. T6 comparisons
may permit Common Takeoff and Landing Credit (CTLC) between
different type-certificated aircraft. In Appendix 2 the details of
these situations provide further amplification.
b. To begin the evaluation process, the applicant identifies
candidate aircraft. The aircraft are then assigned to logical
aircraft groups to be described in Master Difference Requirements
(MDR) tables and the FSB report.
c. The applicant identifies major differences pertinent to the
aircraft and makes comparisons with the proposed candidate aircraft.
A differences document (i.e., an appropriate sample Operator
Difference Requirement (ODR) table) summarizes the identified
differences. Since combinations of related aircraft may be numerous
and only typical differences are needed at this stage for test
definition, the applicant may select representative ODRs for
preparation.
d. Based on the above analysis (including preliminary flight
test results or flight simulation estimates, if available), the
applicant proposes difference levels to be specified in each cell of
the MDR table for the various aircraft combinations.
e. The applicant proposes applicable elements of the test
process (T1 through T5 and T6 for CTLC) and a plan for validation of
the intended difference levels. Specific aircraft, times, devices,
etc. are identified to conduct the required tests for the candidate
aircraft. Included in the proposal are any necessary interpretations
of expected results using established standards. Any special,
unique, or additional definitions of successful outcomes are also
identified.
f. The scope of T1 through T6 is keyed to basic visual flight
rules (VFR) and instrument flight rules (IFR) operations in the
National Airspace System (NAS).
g. FAA/applicant agreement is reached on the grouping of
aircraft, proposed tests, test plans, schedules, subjects, and
interpretation of possible outcomes.
h. Subject qualifications are addressed at the time of test
specification when test agreement is reached with the applicant.
Test subjects for all tests except T6 are drawn from the FAA.
Subject selection considers the factors such as the following:
(1) Needed background skills of candidates (previously qualified
aircraft);
(2) General flight experience and currency;
(3) Test requirements such as location, short notice access, and
skills needed for subjects;
(4) Technical areas, qualifications, or experience that subjects
should not have to avoid test prejudice;
(5) Eventual FAA geographic or operator related distribution
requirements for ASI, APM, and POI personnel; and
(6) Other special experience as needed for a particular program.
i. During preparation for testing and evaluation of results,
appropriate Aircraft Certification Flight Test Branch coordination
is accomplished so that flight characteristic issues and, in
particular, special flight characteristics can be suitably
identified and addressed.
Note: Tests T1 and T2 must be conducted in the candidate
aircraft for the determination of training, checking, and currency
requirements. However, the FSB chairman may elect to use a simulator
before its qualification by the National Simulator Evaluation Team
(NSET). This may be done for selected FSB T-tests that involve
partial-task evaluation of systems or components, which do not
directly relate to aircraft handling qualities or core pilot skills.
These types of tests would normally require only a training device
with no visual or motion capabilities.
[[Page 49618]]
2. Pilot Type Rating Determination Through Analysis-Level A or B
Training Only
a. Typically, with the introduction of a new aircraft, or when
training credit is sought in a comparison of a base and candidate
aircraft, the T1 through T5 testing process determines pilot type
rating. Not all changes or modifications to an aircraft or on
occasion, the certification of a related aircraft may require
flight-testing to assess their impact upon pilot type rating. Pilot
type rating determination through analysis may be considered if the
changes do not influence aircraft handling, introduce no significant
change to systems operation or pilot procedures, and can be
addressed at level A or B training.
b. The analysis process can be used if the aircraft handling has
not changed significantly. In most cases, it should be obvious that
the change will not affect aircraft handling but if additional data
is needed to make the determination, the information can be obtained
from the assigned FAA Aircraft Certification Service (AIR) or
through the applicant's flight test data. Following is a list of
typical changes evaluated through the analysis process:
(1) Maximum operating weights (revised aircraft type certificate
data sheet (TCDS)).
(2) An engine type or thrust change that does not require
significant design changes to aircraft flight controls.
(3) Maximum passenger capacity (revised aircraft TCDS).
(4) Avionic upgrades (Supplemental Type Certificate (STC) or
manufacturer production line upgrade).
(5) Proven electronic flight bag installation, (STC or
manufacturer production line upgrade).
(6) Passenger to cargo conversions.
c. When the analysis process is completed, it is recorded as a
revision to the training courseware and to the existing FSB report
for the base and/or candidate aircraft.
3. Functional Equivalence-Level A or B Test 1 (T1)
a. Test Purpose. The T1 test is conducted to determine if
training level A or B is appropriate between the base and candidate
aircraft.
Note: If the applicant communicates that the training, checking
and currency requirements for the candidate aircraft may exceed
level B, the T1 test can be waived and the evaluation process then
moves directly to the T2 test. By waiving the T1, the applicant
acknowledges that differences exist between the base and candidate
aircraft, and may demand that training, checking, and/or currency
requirements up to but not exceeding level D are applied.
b. Test Subjects. Test subjects are designated FAA FSB members,
trained, experienced, and current on the base aircraft with no
differences training for the candidate aircraft. The applicant may
provide proficiency training to the designated FSB members before
testing begins.
c. Test Process. The applicant initiates the test process when
they propose that the minimum training, checking, and currency
requirements for the base and candidate aircraft are no greater than
level B differences. At the discretion of the FSB chairman, the T1
test may be accomplished in a training device/simulator or airplane
as appropriate. T1 is typically conducted using one group of test
subjects. Subjects will initially be given a ``no jeopardy'' flight
check for their base aircraft to calibrate performance before taking
the pertinent flight check in the candidate aircraft being
evaluated. The flight check undertaken in the candidate aircraft
will address the differences between the base aircraft and candidate
aircraft. The test may be administered or observed by more than one
FSB member to ensure consistency and uniformity of test procedures
and common understanding of subject performance and outcomes.
d. Safety Pilot. A ``safety pilot,'' serving as PIC in the
aircraft and functioning as pilot monitoring in either seat, will
intervene to prevent damage to the aircraft or to limit maneuvers
that endanger safety of flight.
e. Successful Test. FSB members decide the outcome of the T1
test consistent with previously agreed upon criteria. The FSB
determines the areas of differences training required and specifies
necessary devices or training limitations. If the T1 test is passed,
the pertinent aircraft pairs are assigned to level A or level B
training differences. Successful completion of T1 results in
awarding of the same or a common pilot type rating.
f. Failure of Test. If the T1 test is failed and retesting is
not considered, level A or B cannot be assigned. This generally
requires completion of T2 and T3. If requesting training credit, the
applicant may ask for and receive credit for those items passed in
T1. T1 retesting may be considered at the discretion of the FSB.
4. Handling Qualities Comparison Between Aircraft-Test 2 (T2)
a. Test Purpose. The T2 test compares handling qualities between
the base and candidate aircraft to determine whether training level
B, C, or D is appropriate. At the discretion of the FSB chairman the
T2 test may be completed through analysis, without requiring an
aircraft flight. Determining if the analysis process can be used
requires verification that the aircraft handling has not changed
significantly as described in the ``test process''. In most cases,
it should be obvious that the change will not affect aircraft
handling but if the determination requires additional data, the
information is obtained from the assigned FAA Aircraft Certification
Office or through the applicant's flight test data. With FAA
agreement, elements of T2 may be incorporated within the T3 test to
verify that an advanced simulator or aircraft training is not needed
to address handling qualities.
Note: If T2 is conducted on an aircraft that is expected to
require a separate pilot type rating with CTLC, credit will be
validated by using the T6 process.
b. Test Subjects. Test subjects are designated FAA FSB members,
who are trained, experienced and current on the base aircraft with
no differences training for the candidate aircraft. Training to
proficiency may be provided to the designated FSB members by the
applicant before the start of testing.
c. Test Process. The applicant initiates the test process when
they analyze available flight or simulation test data, and aircraft
design or system differences, and determine that handling
similarities exist between the base and candidate aircraft. From
this determination the applicant makes their T2 proposal. Before the
test, representatives of the FSB review the T2 test profile to
ensure that critical handling quality aspects of the candidate
aircraft are examined. The flight evaluation consists of relevant
parts of a proficiency check as determined by the FSB chairman. T2
consists of a comparison between selected pilot certification flight
check maneuvers (normal and nonnormal) administered first in the
base aircraft (using either the actual aircraft or a level C or D
simulator) then in the candidate aircraft. Although T2 testing
should always be accomplished in the candidate aircraft, some
portions that significantly affect aircraft safety, such as flight
control failures, may be conducted in a simulator suitable for the
test. Subject pilots are evaluated on performance of required
maneuvers consistent with standards set by 14 CFR and an assessment
of the degree of difficulty in performing maneuvers in the candidate
aircraft compared to the base aircraft. The test may be administered
or observed by more than one FSB member to ensure consistency and
uniformity of test procedures and common understanding of subject
performance and outcomes.
d. Safety Pilot. The safety pilot serving as PIC in the aircraft
and functioning as pilot monitoring in either seat, will intervene
to prevent damage to the aircraft or to limit maneuvers which
endanger safety of flight. The safety pilot can only assist the
subject pilot in areas unrelated to the handling qualities
determination. For example, the safety pilot can remove impediments
to progression of the test but cannot fly, coach, or train the
subject on any aspect of the test related to handling, vision cues,
or motion cues. The safety pilot may not actuate primary flight
controls during the evaluation, or instruct, lead, or coach test
subjects in any manner. The safety pilot may:
(1) Perform all routine pilot monitoring duties.
(2) Set up or adjust systems, including those normally operated
by the pilot flying in accordance with pretest agreements.
(3) Address or resolve procedural impediments.
(4) Manage and satisfy checklists.
(5) Make normal call outs.
e. Successful Test. The FSB members decide T2 test outcome
consistent with previously agreed upon criteria. Acceptable pilot
performance in completion of designated maneuvers, without
differences training, establishes that the candidate and base
aircraft are sufficiently alike in handling characteristics to
permit assignment of level B, C, or D. The test process can then
advance to differences training and the T3 test.
f. Failure of Test. Failure of T2 means that major handling
differences exist during critical phases of flight or that numerous
less critical differences were identified that warrant training in a
full flight simulator or aircraft. Accordingly, level E differences
will
[[Page 49619]]
be assigned and the FAA will issue a separate pilot type rating.
With a T2 failure, the next step in the testing process is T5, to
validate level E requirements and the proposed training course.
Failure of the T2 does not necessarily mean that the base and
candidate aircraft do not share a high degree of system and/or
handling commonality. The applicant may elect to use the data
collected during the T2 process to justify approval of a shortened
pilot type rating course for pilots that are trained on the base
aircraft and are transitioning to the candidate.
5. System Differences Test and Validation of Training and Checking--
Test 3 (T3)
a. Test Purpose. Test 3 is used to evaluate the proposed
differences training, checking, and training devices at levels B, C,
or D.
b. Test Subjects. Test subjects are designated FAA FSB members,
trained, experienced, and current on the base aircraft with no
differences training for the candidate aircraft. Training to
proficiency may be provided to the designated FSB members by the
applicant before the start of testing.
c. Test Process. T3 is a system differences test and a
validation of training and checking. It is used when the equivalent
handling test (T2) is successfully completed or when T2 is being
incorporated as part of T3. T3 is administered in two phases
following differences training of a pilot in the candidate aircraft.
(1) First Phase. The successful completion of a pilot
certification flight check to assess pilot knowledge, skills, and
abilities pertinent to operation of the aircraft being tested. If a
full check is proposed, the tests are similar to those used for T1
as described in paragraph 2 above. If a partial check is used, the
process is similar, but the FSB determines the test items based on
the applicant`s proposals. The first phase will include either a
proficiency check as defined by 14 CFR, partial proficiency check,
or individual aircraft system operation check administered to pilots
in the simulator or candidate aircraft. The check is administered
assuming currency in the base aircraft and completion of the
proposed training in the candidate aircraft.
(2) Second Phase. Line oriented flying (LOF) following
completion of the flight check. The LOF phase of the test is used to
validate the training and checking being proposed, fully assess
particular difference areas, examine implications of mixed fleet
flying, assess special circumstances such as minimum equipment list
(MEL) effects, and identify the effects of pilot errors potentially
related to the differences. The test is done in a real line flight
environment that includes typical weather, routes, airports, air
traffic control (ATC), and other factors that are characteristic of
those in which that aircraft will be operated. LOF tests may be
conducted in test aircraft, simulators, or with a combination of
these in conjunction with function and reliability certification
tests. The LOF portion of the test may be used to evaluate complex
issues or issues that cannot be fully detailed in a brief flight
check since a check only samples pilot knowledge and skills in a
limited and highly structured environment. LOF is an integral part
of T3 and must be successfully completed before ``initial''
assignment of difference levels. In developing and selecting
scenarios for evaluation consider the following:
(a) Likelihood of occurrence;
(b) Possible consequences; and
(c) The timeliness of pilot discovery and correction.
d. Successful Test. The FSB members decide the outcome of the T3
consistent with previously agreed upon criteria and completion of
LOF with appropriate pilot performance. Passing T3 leads to setting
respective difference levels and validates differences training and
checking at level B, C, or D between related aircraft.
e. Failure of Test. Failure of T3 occurs with either failure of
the check, agreed criteria, or unsatisfactory performance during the
LOF portion of the test. In certain failure cases, T3 can lead to
assignment of level E and a separate pilot type rating. The
following are examples that may lead to the assignment of level E
differences:
(1) T3 experience or difficulties that show the need for
assignment of training levels approaching typical initial/transition
levels.
(2) T3 pilot performance that indicates that devices or methods
associated with level D are not adequate to achieve training or
checking objectives.
(3) Repeated failures of attempts to pass T3 test at level D
training differences. In the case of retesting, new subjects may be
required at the discretion of the FSB Chairman.
Note: Repeated failure of test at level D differences by one or
more subject's (pilot) inadequate performance, that is not an
individual subject's failure due to sub-par or atypical personal
performance as determined by the FSB, may lead to assignment of
level E differences.
6. Currency Validation--Test 4 (T4)
a. Test Purpose. The T4 test is a currency test that can be used
when an applicant seeks relief from existing FSB currency
requirements. In the context of this AC, currency addresses system
procedural and maneuver differences between related aircraft. T4
does not include takeoff and landing recency of experience.
b. Test Subjects. Designated FAA FSB members.
c. Test Process. If an applicant desires a change in the
currency requirements, a T4 test may be conducted. This test may be
done before or after the aircraft enters into service. In the event
the test cannot be done before entry into service, the FSB
established limits apply. Criteria that may be used by the FSB to
set level B, C, D differences for currency for initial FSB
determinations include the following examples:
(1) Complex flight critical systems affecting control or
navigation.
(2) Critical nonnormal maneuvers differing between related
aircraft (e.g., V1 engine failure, emergency descent, etc.),
requiring one acceptable demonstration/training or checking event
(typically 6 months but demonstration period may also vary by pilot
position).
(3) Secondary systems (e.g., Oxygen or auxiliary power unit
(APU)).
d. Successful Test. The FSB members decide the outcome of T4
consistent with previously agreed upon criteria. A successful test
validates that the proposed less restrictive currency provisions are
accepted as a means of compliance with applicable rules, provisions
of this AC, and/or currency provisions and provide an equivalent
level of safety.
e. Failure of Test. Failure indicates that the proposed less
restrictive currency requirements do not provide an equivalent level
of safety. At the discretion of the FSB, retesting may be
appropriate.
7. Initial or Transition Training/Checking Program Validation--Test 5
(T5)
a. Test Purpose. T5 test validates the applicant's training
course(s) at level E (new pilot type rating). It is appropriate
when:
(1) A full initial or transition training/checking program
requires validation;
(2) An applicant seeks training credits between two aircraft
with different pilot type ratings (a typical goal under shortened
training programs); or
(3) T2 or T3 are failed.
b. Test Subjects. Designated FAA FSB members.
c. Test Process. There are two methods to accomplish the T5 test
process:
(1) Full Initial or Transition Training/Checking Program
Validation. This method is used when an applicant has developed an
aircraft and seeks a new pilot type rating without any credit for
commonality with any related aircraft. The applicant develops a
training program to qualify and check pilots in the candidate
aircraft at level E differences. Subjects are trained, given flight
proficiency checks and complete LOF in a process similar to that
described in paragraph 5.
(2) Shortened Transition Training/Checking Program Validation.
This method is used when an applicant has developed an aircraft and
seeks a new pilot type rating and credit for commonality with
related aircraft. The applicant conducts a handling-qualities
evaluation based on the applicant's proposed ODR tables (similar to
T2), followed by training and checking program validation (similar
to T3). Subjects are trained, given flight proficiency checks and
complete LOF in a process similar to that described in paragraph 5.
Note: When an aircraft is assigned level E differences because
of a failure of T3 test at level D differences, credit for
successfully passing individual elements of the T3 test may be used
as justification for not duplicating those elements in the T5 test.
d. Successful Test. The FSB members decide the T5 outcome
consistent with previously agreed upon criteria. A successful
outcome of T5 validates the proposed training and checking programs.
e. Failure of Test. Failing T5 indicates the proposed training
or checking programs require modification. A retest by mutual
agreement between the FSB and applicant would normally be required.
8. Common Takeoff and Landing Credit (CTLC)--Test 6 (T6)
a. Test Purpose. The applicant uses T6 when they seek credit
between related aircraft toward the takeoff and landing
[[Page 49620]]
recency of experience requirements of the applicable 14 CFR parts.
b. Test Subjects. The test should consist of a sufficient number
of pilots not trained or qualified in the candidate aircraft. These
subjects will be drawn from the manufacturer, industry and the FAA
that the FSB determines will represent a statistically relevant
cross-section of operational pilots. The participants' experience
levels, pilot type ratings and airplane currency should reflect the
proficiency difference levels needed to validate testing
assumptions.
c. Test Process. Test subjects are first provided refresher
training in the base aircraft to establish a baseline of
proficiency, then placed in the candidate aircraft, without any
training in it, and perform a minimum of three takeoffs and landings
without use of the autopilot. It may not be practical to conduct
some tests in an aircraft. A simulator may be used to conduct these
tests. Test subjects should be evaluated on their ability to fly the
aircraft manually through takeoff, initial climb, and approach and
landing (including the establishment of final landing
configuration). The applicant should consider the effects on the
takeoff and landing maneuvers for the following factors when
designing the T6 test:
(1) Aircraft weights.
(2) Aircraft center of gravity.
(3) Takeoff and landing crosswinds.
d. Successful Test. The FSB members decide the outcome of T6
consistent the FAA Practical Test Standards (PTS) demonstrating that
an equivalent level of safety can be maintained when full or partial
credit for takeoffs and landings is given between the related
aircraft.
e. Failure of Test. The test subjects' performance relative to
the FAA PTS demonstrates an equivalent level of safety cannot be
maintained when either full or partial credit for takeoffs and
landings is given between the related aircraft.
