Establishment of Class D Airspace: Destin, FL; Duke Field, Eglin AFB, FL; Revocation of Class D Airspace; Eglin AF Aux No 3 Duke Field, FL; and Amendment of Class D and E Airspace; Eglin Air Force Base, FL; Eglin Hurlburt Field, FL; and Crestview, FL

This action establishes Class D airspace at Destin, FL, providing the controlled airspace required for the Air Traffic Control Tower at Destin Executive Airport, (formerly Destin-Fort Walton Beach Airport). Additionally, this action removes Eglin AF Aux No 3 Duke Field from the Class D designation, and establishes Duke Field, Eglin AFB, FL in its place. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport. This action also changes the existing Class D airspace designation at Duke Field, Eglin Air Force Base (AFB), FL, and adjusts the geographic coordinates of Eglin AFB, Destin Executive Airport, Duke Field, and Hurlburt Field, to stay in concert with the FAA's database.
