Proposed Establishment of Low Altitude Area Navigation Routes (T-Routes); Sacramento and San Francisco, CA
Notice Of Proposed Rulemaking (Nprm).
This action proposes to establish four low altitude Area Navigation (RNAV) routes, designated T-257, T-259, T-261 and T-263 in the Sacramento and San Francisco, CA, terminal areas. 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 Sacramento and San Francisco, CA, terminal areas.

History Back to Top
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 FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 to establish four low altitude RNAV routes in the Sacramento and San Francisco, CA, terminal areas. The routes would be designated T-257, T-259, T-261 and T-263, 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 Sacramento and San Francisco, CA, terminal areas.
Low altitude RNAV routes are published in paragraph 6011 of FAA Order 7400.9R signed August 15, 2007 and effective September 15, 2007, 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.
The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority.
This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it establishes RNAV T-Routes at Sacramento and San Francisco, CA.
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.
