Amendment of Class D and E Airspace; Alpena, MI
This action amends the Class D airspace, the Class E surface airspace, the Class E airspace designated as an extension to Class D and Class E surface airspace, and the Class E airspace extending upward from 700 feet above the surface at Alpena County Regional Airport, Alpena, MI. This action is due to an airspace review caused by the decommissioning of the Au Sable VHF omnidirectional range (VOR) navigation aid, which provided navigation information for the instrument procedures at this airport, as part of the VOR Minimum Operational Network (MON) Program. The name of MidMichigan Medical Center-Alpena, Alpena MI, is also being updated to coincide with the FAA's aeronautical database. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
