Establishment, Modification, and Revocation of Class E Airspace; Alaska, AK

This action proposes to establish Class E domestic en route airspace (Class E6) within a designated landmass and within 12 miles from a designated coastline associated with the state of Alaska to facilitate the vectoring of instrument flight rules (IFR) aircraft on direct routes where the current en route structure is insufficient or improper within the proposed airspace area. Due to redundancy, this action also proposes to remove two Class E6 airspace areas, remove two Class E airspace areas extending upward from 1,200 feet above the surface, and modify 101 Class E airspace areas extending upward from 700 feet or more above the surface of the earth (Class E5) to remove any portion extending upward from 1,200 feet above the surface due to redundancy. Finally, this action proposes administrative amendments to the legal descriptions of 48 Class E5 airspace areas. This action would support IFR operations while enhancing the safety and management of aircraft operations within the National Airspace System (NAS).
