Proposed Modification of the Norton Sound Low, Woody Island Low and 1234L Offshore Airspace Areas; AK

摘要

This action proposes to amend the Norton Sound Low, Woody Island Low and 1234L Offshore Airspace Areas in Alaska. Specifically, this action proposes to modify the Norton Sound Low Offshore Airspace Area in the vicinity of the Toksook Bay Airport, Toksook Bay, AK, by lowering the Offshore airspace floor to 1,200 feet mean sea level (MSL) within a 35-mile radius from a defined point just south of the airport. This action also proposes to modify the Woody Island Low and 1234L Offshore Airspace Areas in the vicinity of the Chignik Airport, Chignik, AK, by lowering the Offshore airspace floors to 1,200 feet MSL within a 72.8-mile radius from the Chignik Airport. Additional controlled airspace is necessary for the safety of instrument flight rules (IFR) operations at the Toksook Bay and Chignik Airports.
