## Abstract

This action revises three Very High Frequency Omnidirectional Range (VOR) Federal airways southeast of Missoula, MT (V-2, V-257, and V-343). These VOR Federal airways are being revised due to the decommissioning of the Drummond VOR. These changes will enhance air safety, simplify routings, and reduce controller workload in Montana.
