## Abstract

This action amends the Class E airspace areas at Boise Air Terminal (Gowen Field), Boise, ID. This action also adjusts the geographic coordinates of the airport. The Boise VHF Omni-Directional Radio Range Tactical Air Navigational Aid (VORTAC) is no longer needed as a reference. The Donnelly Tactical Air Navigation System (TACAN) has been decommissioned and controlled airspace reconfigured. This action also makes a minor change to the legal description in reference to Class E airspace 9,000 feet Mean Sea Level (MSL). This improves the safety and management of Instrument Flight Rules (IFR) operations at the airport.
