14 CFR Part 71
[Airspace Docket No. 97-ANM-02]
Amendment of Class E Airspace; Alamosa, CO
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This action modifies the Alamosa, CO, Class E airspace by
increasing the radius of the Class E surface area, and by expanding the
lateral boundaries of the Class E airspace at and above 1,200 feet
Above Ground Level (AGL). The additional controlled airspace is
necessary to contain two Standard Instrument Approach Procedures (SIAP)
which have recently been developed for the Alamosa Airport. The
intended effect of this action is to provide the additional controlled
airspace necessary to enable the FAA to provide Instrument Flight Rules
(IFR), Air Traffic Control (ATC) services and separation to IFR
aircraft operating on the SIAP's and transitioning between the terminal
and en route environments. The areas will be depicted on aeronautical
charts for pilot reference.
EFFECTIVE DATE: 0901 UTC, November 19, 1997.

SUPPLEMENTARY INFORMATION:
History
On April 2, 1997, the FAA proposed to amend Part 71 of Federal
Aviation Regulations (14 CFR part 71) to provide additional Class E
airspace area at Alamosa, Colorado (62 FR 15635). The recent
commissioning of the Alamosa Instrument Landing System (ILS), and
Global Positioning System (GPS) SIAP requires adjustment of Class E
airspace in order to segregate aircraft operating in instrument flight
conditions from aircraft operating in visual flight conditions.
Interested parties were invited to participate in the rulemaking
proceeding by submitting written comments on the proposal. No comments
were received. The coordinates for this airspace docket are based on
North American Datum 83. This action is the same as described in the
proposal. Class E airspace designated as a surface area for an airport
and airspace designations for airspace areas extending upward from 700
feet or more above the surface of the earth are published in paragraph
6002 and paragraph 6005 of FAA Order 7400.9E, dated September 10, 1997,
and effective September 16, 1997, which is incorporated by reference in
14 CFR 71.1. The Class E airspace designation listed in this document
will be published subsequently in the Order.
The Rule
This action amends 14 CFR part 71 Class E airspace at Alamosa, CO.
The portion of the existing airspace area extending upward from the
surface will be expanded by increasing the radius of the area from 4.3
nautical miles (NM) to 5 NM. Where a SIAP has been designated for the
airport and communications and weather reporting criteria are met, the
FAA establishes Class E airspace extending upward from the surface to
the base of overlying controlled airspace to contain terminal
instrument operations if such action is justified and/or in the pubic
interest. This action also expands and simplifies the portion of the
area extending upward from 1,200 feet AGL by redefining the lateral
boundaries of the area. The FAA establishes Class E airspace extending
upward from 1,200 feet AGL where necessary to contain aircraft
transitioning between the terminal and en route environments. The FAA
has recently established GPS and ILS SIAP's for use by aircraft
arriving at the Alamosa Airport. The additional Class E airspace
established by this rule is necessary to accommodate the new SIAP's.
The intended effect of this action is to provide the controlled
airspace necessary to enable the FAA to provide IFR ATC services and
separation to IFR aircraft operating on the GPS and ILS SIAP's, and
while transitioning between the en route and terminal environments. The
areas will be dipicted on appropriate aeronautical charts for pilot
reference.
[[Page 54380]]
The FAA has determined that this proposed regulation only involves
an established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current.
It, therefore, (1) is not a ``significant regulatory action'' under
Executive Order 12866; (2) is not a ``significant rule'' under DOT
Regulatory Policies and Procedures (44 FR 11034; February 26, 1979);
and (3) does not warrant preparation of a regulatory evaluation as the
anticipated impact is so minimal. Since this is a routine matter that
will only affect air traffic procedures and air navigation, it is
certified that this rule will not have a significant economic impact on
a substantial number of small entities under the criteria of the
Regulatory Flexibility Act.
