Proposed Establishment, Modification and Revocation of Air Traffic Service (ATS) Routes; Western United States

This action proposes to modify three jet routes and four VHF Omnidirectional Range (VOR) Federal airways; remove two VOR Federal Airway routes, and establish four and modify four low altitude Area Navigation (RNAV) routes (T-routes) in the western United States. The FAA is proposing this action due to the scheduled decommissioning of the Manteca, CA, and Maxwell, CA, VOR facilities, which provide navigation guidance for portions of the affected routes. This action would enhance the safety and management of aircraft within these routes in the National Airspace System (NAS).
