## Abstract

This action establishes a low altitude Area Navigation (RNAV) route, designated T-276. The NPRM incorrectly indicated the route location in Southwest Oregon, however the route is in Southwest Washington. 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 taking this action to reduce controller workload, enhance safety and improve the efficient use of the navigable airspace into and through the Portland, Oregon, terminal area.
