Proposed Amendment of Norton Sound Low and Control 1234L Offshore Airspace Areas; Alaska

概要

This action proposes to modify the Norton Sound Low and Control 1234L Offshore Airspace Areas in Alaska. This action would lower the airspace floors 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.
