Proposed Modification of Offshore Airspace Areas: Norton Sound Low, Control 1234L and Control 1487L; Alaska

الملخص

This action proposes to modify the Norton Sound Low, Control 1234L, and Control 1487L Offshore Airspace Areas in Alaska. The airspace floors would be lowered to provide controlled airspace beyond 12 miles from the coast of the United States given that there is a requirement to provide Instrument Flight Rules (IFR) en route Air Traffic Control (ATC) services and within which the United States is applying domestic ATC procedures.
