Proposed Amendment of Class D and Class E Airspace, Revocation of Class E Airspace; Mountain Home, ID

This action proposes to modify Class D airspace, Class E surface area airspace, Class E airspace extending upward from 700 feet above the surface, and remove Class E surface area airspace designated as an extension at Mountain Home AFB, Mountain Home, ID. After reviewing the airspace, the FAA found it necessary to increase the Class D airspace area and reduce the Class E airspace areas for the safety and management of Instrument Flight Rules (IFR) operations for arriving and departing aircraft at the airport. This action also would initiate the use of geographic coordinates as reference points instead of navigation aids to describe the controlled airspace areas, and would update the geographic coordinates of Mountain Home Municipal Airport.
