Specifically, this action revises the boundaries of the Air Defense Identification Zones surrounding the contiguous United States and Alaska and amends the flight plan and communications requirements for pilots planning flight into, within, or whose departure point is within any of these zones. This action conforms the security control of air traffic regulations with Presidential Proclamation No. 5928; supports the Department of Defense in accomplishing its national defense and drug interdiction missions; and assists law enforcement agencies in their efforts to stop the transportation of illegal drugs by aircraft.
