## Abstract

This action establishes the Hawaiian High and Hawaiian Low Offshore airspace areas. This action establishes Class A airspace, extending upward from 18,000 feet mean sea level (MSL) to and including flight level (FL) 600; and Class E airspace, extending upward from 1,200 feet MSL to and including 17,999 feet MSL around the Hawaiian Islands. The action provides additional airspace within which domestic air traffic control (ATC) procedures will be used. Establishment of the Class A and Class E airspaces enhances the management of air traffic operations resulting in a more efficient use of that airspace.
