14 CFR Proposed Rule 2020-08289
Proposed Amendment of Area Navigation (RNAV) Routes T-325 and T-354; Northcentral United States
July 13, 2020

Notice of proposed rulemaking (NPRM).


This action proposes to modify low altitude RNAV routes T-325 and T-354 in the northcentral United States. The proposal would expand the availability of RNAV routing in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation.


Comments must be received on or before June 5, 2020.

Authority for This Rulemaking

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 would expand the availability of RNAV in the northcentral United States and improve the efficient flow of air traffic within the NAS by lessening the dependency on ground-based navigation.

Comments Invited

Interested parties are invited to participate in this proposed rulemaking by submitting such written data, views, or arguments as they may desire. Comments that provide the factual basis supporting the views and suggestions presented are particularly helpful in developing reasoned regulatory decisions on the proposal. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal.

Communications should identify both docket numbers (FAA Docket No. FAA-2020-0294; Airspace Docket No. 20-AGL-8) and be submitted in triplicate to the Docket Management Facility (see ADDRESSES section for address and phone number). You may also submit comments through the internet at https://www.regulations.gov.

Commenters wishing the FAA to acknowledge receipt of their comments on this action must submit with those comments a self-addressed, stamped postcard on which the following statement is made: “Comments to FAA Docket No. FAA-2020-0294; Airspace Docket No. 20-AGL-8.” The postcard will be date/time stamped and returned to the commenter.

All communications received on or before the specified comment closing date 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 examination in the public docket both before and after the comment closing date. A report summarizing each substantive public contact with FAA personnel concerned with this rulemaking will be filed in the docket.

Availability and Summary of Documents for Incorporation by Reference

This document proposes to amend FAA Order 7400.11D, Airspace Designations and Reporting Points, dated August 8, 2019, and effective September 15, 2019. FAA Order 7400.11D is publicly available as listed in the ADDRESSES section of this document. FAA Order 7400.11D lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.


In 2003, Congress enacted the Vision 100—Century of Aviation Reauthorization Act (Pub. L., 108-176), which established a joint planning and development office in the FAA to manage the work related to the Next Generation Air Transportation System (NextGen). Today, NextGen is an ongoing FAA-led modernization of the nation's air transportation system to make flying safer, more efficient, and more predictable.

In support of NextGen efforts to improve the safety and efficiency of the NAS, as well as transition the NAS from a ground-based to a satellite-based Performance Based Navigation (PBN) system, the FAA is proposing to amend RNAV routes T-325 and T-354 by extending them to provide additional PBN enroute structure. This action would reduce air traffic control (ATC) sector workload and complexity, reduce pilot-to-controller communication, and increase NAS capacity in the areas of the extensions. Additionally, the extensions of these RNAV routes would assist ATC when non-radar procedures are required.

The Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 to amend RNAV routes T-325 and T-354. The proposed route changes are described below.

T-325: T-325 currently extends between the Bowling Green, KY, VHF Omnidirectional Range (VOR)/Tactical Air Navigation (VORTAC) navigation aid and the Terre Haute, IN, VORTAC. The proposed change would remove the Terre Haute VORTAC and replace it with the JIBKA, IN, waypoint (WP) (located near the Terre Haute VORTAC), and extend the route northward from the JIBKA, IN, WP to the Oshkosh, WI, VORTAC. The following points would be added between the JIBKA WP and the Oshkosh VORTAC: CAPPY, IL, WP; SMARS, IL, WP; TRENM, IL, WP; START, IL, WP; GRIFT, IL, WP; DEBOW, WI, WP; LUNGS, WI, WP; and the HOMNY, WI, WP. Additional changes to other portions of the airway have been proposed in a separate NPRM. The unaffected segments of the existing route would remain as charted.

T-354: T-354 currently extends between the Park Rapids, MN, VOR/Distance Measuring Equipment (VOR/DME) navigation aid and the Siren, WI, VOR/DME. The proposed change would remove the Siren VOR/DME and replace it with the SSKYY, WI, WP (located over the Siren VOR/DME), and extend the route southeastward from the SSKYY, WI, WP to the Cunningham, KY, VOR/DME. The following points would be added between the SSKYY WP and the Cunningham VOR/DME: TONOC, WI, FIX; KOETZ, WI, WP; HRMNN, WI, WP; FOMAG, WI, WP; MAYSE, WI, WP; HOMRC, IL, WP; CPTON, IL, WP; BLLUE, IL, WP; BOSTN, IL, WP; and the Bible Grove, IL, VORTAC. Additional changes to other portions of the airway have been proposed in a separate NPRM. The unaffected segments of the existing route would remain as charted.

The existing latitude/longitude coordinates in the descriptions of T-325 and T-354 would be adjusted to the hundredths of a second place to provide greater accuracy for RNAV navigation.

Low altitude RNAV routes are published in paragraph 6011 of FAA Order 7400.11D, dated August 8, 2019, and effective September 15, 2019, which is incorporated by reference in 14 CFR 71.1. The RNAV routes listed in this document would be subsequently published in the Order.

FAA Order 7400.11, Airspace Designations and Reporting Points, is published yearly and effective on September 15.

Regulatory Notices and Analyses

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 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

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1F, “Environmental Impacts: Policies and Procedures” prior to any FAA final regulatory action.
