14 CFR Part 71

[Docket No. FAA-2007-27332; Airspace Docket No. 07-AWP-2]


Proposed Establishment of Low Altitude Area Navigation Routes (T-
Routes); Los Angeles, CA

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This action proposes to establish three low altitude Area 
Navigation (RNAV) routes, designated T-245, T-247, and T-249 in the Los 
Angeles International Airport, CA, terminal area. T-routes are low 
altitude Air Traffic Service (ATS) routes, based on RNAV, for use by 
aircraft having instrument flight rules (IFR) approved Global 
Positioning System (GPS)/Global Navigation Satellite System (GNSS) 
equipment. The FAA is proposing this action to enhance safety and 
improve the efficient use of the navigable airspace in the Los Angeles 
International Airport, CA, terminal area.

DATES: Comments must be received on or before June 7, 2007.

ADDRESSES: Send comments on this proposal to the Docket Management 
System, U.S. Department of Transportation, Room Plaza 401, 400 Seventh 
Street, SW., Washington, DC 20590-0001. You must identify FAA Docket 
No. FAA-2007-27332 and Airspace Docket No. 07-AWP-2, at the beginning 
of your comments. You may also submit comments through the Internet at

postcard will be date/time stamped and returned to the commenter.
    All communications received on or before the specified closing date 
for comments will be considered before taking action on the proposed 
rule. The proposal contained in this action may be changed in light of 
comments received. All comments submitted will be available for

    Persons interested in being placed on a mailing list for future 
NPRM's should contact the FAA's Office of Rulemaking, (202) 267-9677, 
for a copy of Advisory Circular No. 11-2A, Notice of Proposed 
Rulemaking Distribution System, which describes the application 
procedure.

Low Altitude RNAV Route Identification and Charting

    Low altitude RNAV routes are identified by the letter ``T'' prefix 
followed by a three digit number. The ``T'' prefix is one of several 
International Civil Aviation Organization designators used to identify 
domestic RNAV routes. The FAA has been allocated the letter ``T'' 
prefix and the number block 200 to 500 for use in naming these routes. 
The FAA uses the ``T'' prefix for RNAV routes in the low altitude en 
route structure of the National Airspace System.
    T-routes are depicted in blue on the appropriate IFR en route low 
altitude chart(s).
    Each route depiction includes a GNSS minimum en route altitude to 
ensure obstacle clearance and communications reception.

The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) part 71 to establish three low altitude RNAV 
routes in the Los Angeles International Airport, CA, terminal area. The 
routes would be designated T-245, T-247, and T-249, and would be 
depicted on the appropriate IFR En Route Low Altitude charts. T-routes 
are low altitude RNAV ATS routes, similar to Very High Frequency 
Omnidirectional Range Federal airways, but based on GNSS navigation. 
RNAV-equipped aircraft capable of filing flight plan equipment suffix 
``G'' may file for these routes.
    The T-routes described in this notice are being proposed to enhance 
safety, and to facilitate the more flexible and efficient use of the 
navigable airspace for en route IFR operations transitioning through 
and around the Los Angeles Class B airspace area.
    Low altitude RNAV routes are published in paragraph 6011 of FAA 
Order 7400.9P, dated September 1, 2006 and effective September 15, 
2006, which is incorporated by reference in 14 CFR 71.1. The low 
altitude RNAV routes listed in this document would be published 
subsequently in the Order.
    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. 
Therefore, this proposed regulation: (1) Is not a ``significant 
regulatory action'' under Executive Order 12866; (2) is not a 
``significant rule'' under Department of Transportation (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 proposed rule, when promulgated, will not have a 
significant economic impact on a substantial number of small entities 
under the criteria of the Regulatory Flexibility Act.

Environmental Review

    The FAA has determined that this action qualifies for categorical 
exclusion under the National Environmental Policy Act in accordance 
with FAA Order 1050.1E, ``Environmental Impacts: Policies and 
Procedures,'' paragraph 311a, 311b, and 311k. This airspace action is 
not expected to cause any potentially significant environmental 
impacts, and no extraordinary circumstances exist that warrant 
preparation of an environmental assessment.
