DEPARTMENT OF TRANSPORTATION
Weather Observation Service Standards
AGENCY: Federal Aviation Administration (FAA) DOT.
ACTION: Notice of policy statement.
-----------------------------------------------------------------------
SUMMARY: The American people have demanded a smaller, more efficient
government; toward that end, the resources of the National Airspace
System must be streamlined and service provided in a safe yet
economical way. In November 1994, senior management officials from the
Federal Aviation Administration (FAA) and the National Weather Service
(NWS) met with executives from fourteen national aviation associations
concerning surface aviation observation services. They reached an
agreement that the government would work with industry to define
various support levels for surface observations.
In addition, in March 1995, and in accordance with the Office of
Management and Budget (OMB) policy, the FAA began the process to assume
responsibility for aviation surface weather observations beginning in
FY 1996. As the NWS automates field offices and reallocates their
personnel under this plan, the FAA will undertake accountability for
observations at many NWS ASOS sites. The NWS has begun transitioning
these ASOS sites to the FAA as the ASOSs are commissioned and has
solicited public comment (61 FR 19595; May 2, 1996). The FAA also
expanded by more than two hundred, the sites to receive ASOSs, thus
enhancing safety at sites without weather observations. All of these
activities prompted the FAA to take aggressive action in addressing
surface aviation observation requirements and do it within modest
resource gains.
As a result, a government/industry team has worked for a year and a
half to comprehensively reassess the requirements for surface
observations at the nation's airports. That work has resulted in
agreement on a set of service standards as well as the FAA and NWS
Automated Surface Observing System (ASOS) sites to which the standards
will apply. This notice outlines the four kinds of service, explains
the method used to determine which airports receive which type of
service, and contains a listing of the airports and the service
categories in which they fall. The FAA, NWS and Industry
representatives believe the service standards approach supports the
best allocation of scarce resources.

SUPPLEMENTARY INFORMATION: The term Service Standards refers to four
levels of detail in the weather observation at sites where there is a
commissioned ASOS. The first category, known as Service Level D, is
completely automated service, at which the ASOS observation will
constitute the entire observation, i.e., no additional weather
information is added by a human weather observer. A partial list of the
airports that fit in this category are provided at the end of this
Notice. Some of these airports currently have contract weather
observers providing the service. Many other sites (60-80) will be
expanded to include automated systems; they are currently under review.
Information on specific additional sites is available upon request.
The second category, tower-augmented service, also known as Service
Level C, encompasses approximately two hundred and fifty airports. At
this level, a human observer adds additional information to the
automated observation. Augmentation includes the following parameters:
thunderstorms, tornadoes, hail, virga, volcanic ash, and tower
visibility. In addition, in the event of an ASOS malfunction or the
ASOS reporting unrepresentative data, the human observer may insert the
correct value or more representative information into the observation.
This is referred to as backup.
Backup consists of inserting the following parameters where
available: wind, visibility, precipitation/obstruction to vision type,
cloud height, sky cover, temperature, dewpoint and altimeter setting.
This level of service would be provided at all towered airports during
hours of operation. During hours that the tower is closed, the ASOS
will provide observations without backup or augmentation. These
airports are listed as tower-agumented (Service Level C) airports at
the end of this notice. Although this category is listed as tower-
agumented, the service may be provided by Flight Service Stations at
selected sites.
At 135 airports, adding more detail to the weather observation was
considered optimum. These airports were divided into two categories,
major aviation hubs and high traffic volume airports with average or
worse weather, referred to as Service Level A airports; and the
remaining group of airports that are smaller hubs or special airports
in other ways, that have worse than average bad weather operations for
thunderstorms and/or freezing/frozen precipitation, and/or that are
remote airports, referred to as Service Level B airports.
Service Level B airports will receive augmentation and backup (C-
level service) plus long-line Runway Visual Range (RVR), which may be
an instantaneous readout. If observed, the following elements will be
added to the observation: freezing drizzle versus freezing rain, ice
pellets, snow depth and snow increasing rapidly remarks, thunderstorm/
lightning location remarks and observed significant weather not at the
station remarks. At selected airports in this category, during
[[Page 32888]]
hours of low traffic volume, the service may revert to Service Level C,
tower-augmented service, or Service Level D, automated service.
Service Level A airports will receive, in addition to the services
described above, 10 minute long-line RVR or additional visibility
increments of \1/8\/, \1/16\ and 0. If observed, the following elements
will be added to the observation: sector visibility, variable sky
condition, cloud layers above 12,000 feet and cloud types, widespread
dust, sand and other obscurations and volcanic eruptions.
At selected sites, Flight Service Stations may do the support at
Level A, B, or C airports. In lieu of a contract of NWS observer at a
Level A, B or C airport, a non-government entity, such as a Fixed Base
Operator or commercial aviation operator may agree to provide
augmentation or backup to the ASOS observation, at no cost to the
government. On a case-by-case basis, arrangements can be made to
install an operator interface device, provide training materials, and
determine a payment schedule for any recurring costs associated with
the activity.
More detailed information on Service Standard procedures, including
augmentation and backup, is contained in FAA Order 7900.5A. This
document is available upon request.
Implementation Schedule
The date for implementation of Service Standards for each airport
will be based upon a number of factors, including NWS transition dates,
ASOS commissioning dates and the FAA budget. Sufficient budget for
implementing Service Levels has been requested for FY 97. However, FAA
budget resources are insufficient in FY 96 to fully fund observations
at the A and B Service Levels at all sites designated for those Service
Standards. For Level 5 towered sites, the FAA has already allocated
funds for Service Level A support to begin immediately upon
commissioning of ASOS; those sites are identified by an asterisk in the
list at this end of this Notice.
The implementation date will be included in a Notice to Airmen and/
or in the Airport/Facility Directory when transition is imminent.
Information on the schedule for specific sites is available on request.
Ranking Process
The criteria used to rank the airports were based on (1) occurrence
of significant weather weighted by traffic counts; (2) distance to the
nearest suitable alternate airport; and (3) critical airport
characteristics. These criteria produced a score for each airport which
determined their level of service. Seventy-eight ASOS sites have the
greatest augmentation needs and will receive expanded service (Level
A); fifty-seven to receive enhanced service (Level B); two hundred and
fifty to receive tower augmentation (Level C); and another nearly four
hundred to receive automated service (Level D). The composite scores
assigned were solely based on weighted objective criteria designed to
capture critical airport characteristics as follows.
Bad Weather Operations Score
This score is calculated by (1) adding the percentage of times that
the airport is impacted by thunderstorms, freezing and/or frozen
precipitation (including freezing rain, freezing drizzle, snow, snow
pellets, snow squalls, snow showers, ice pellets, ice pellet showers,
ice crystals), and visibility less than or equal to .5 mile and
multiplying that percentage sum times total operations at that airport;
(2) multiplying the percentage of time the airport experiences
visibility less than or equal to 3 miles times the number of all
operations and then multiplying that figure by .5; (3) summing the
figures from steps 1-2 above; and (4) setting the resultant figures to
a linear scale ranging from 0 to 18. The total score range was set at 0
to 18 to coincide with the combined total score range of the airport
characteristics and the alternate airport criteria as described in the
next two paragraphs. The traffic count data utilized is FY 1994.
For sites that did not have any weather information available, an
alternate method was devised to compute weather scores. Each airport
which had a composite score of 2 or more, even without weather data,
was assigned weather information (surrogate weather) from the nearest
airport with similar weather. This step was omitted for airports with a
non-weather composite score of less than 2 because adding even a high
weather score to such sites would not cause them to need expanded
service. A list of these airports and the surrogate weather utilized
for them is available upon request.
Score for Distance to Nearest Suitable Alternate Airport
This score gives credit for airports for which the nearest suitable
alternate is a greater distance away. Where available, these alternates
were selected from an Air Transport Association-provided list of actual
alternates utilized for certain airports. Otherwise, an automated
approach was used to determine these alternates based on the following
requirements
The alternate site must have some observation
capabilities. It must be an FAA or NWS ASOS site; an FAA or NWS
contract weather observer observation site; a Federal or Non-Federal
Automated Weather Observing Site (AWOS) site; or a Supplementary
Aviation Weather Reporting Site (SAWRS) station.
If the destination airport has a Terminal Airdrome
Forecast (TAF) issued, the alternate site must have a TAF issued also.
If the destination airport is a Part 139 airport, the
alternate site must be a Part 139 airport also.
The scoring was done using Table 1.

Ranking
The scores from the three areas described above were then added
together and each airport was assigned a composite score and ranked
accordingly. Information on the process of determining the exact
boundaries between service levels, as well as scores for individual
airports, are available upon request.
This following list includes the service level categories and the
airports that fall into each category. The airports in each service
level category are listed by state and the city where the airport is
located. The airport's three letter location identifier is also
included. For
