Establishment and Revision of Area Navigation (RNAV) Routes; Western United States

This action establishes three area navigation (RNAV) routes and revises one existing RNAV route in the Western United States (U.S.) in support of the High Altitude Redesign (HAR) program. The FAA originally proposed to revise two area navigation routes as part of this action, but one revised route (Q-11) was deleted because the proposed change provided limited benefit. The FAA is taking this action to enhance safety and to improve the efficient use of the navigable airspace in the Western U.S.
