terminal guidance

1. The guidance applied to a guided missile between midcourse guidance and arrival in the vicinity of the target.
2. Electronic, mechanical, visual, or other assistance given an aircraft pilot to facilitate arrival at, operation within or over, landing upon, or departure from an air landing or airdrop facility.
3. Any electronic, mechanical, voice or visual communication that provides approaching aircraft or weapons additional information regarding a specific location or target. Terminal guidance is not a type of air control. Those providing terminal guidance do not have weapons release authority, or authority to direct the maneuver of aircraft. See also terminal control.
