The ability of the military pilot to maintain situation awareness (SA) has been recognized in the pilot community as crucial to mission success and survival. Traditionally, pilot training has focused on instruction in the operation of on-board technologies, procedural information for normal flight and emergency conditions, and deployment tactics. These programs alone are not enough, however. Training programs that focus directly on the development of pilot SA are greatly needed. A cognitive model and formal definition of SA are presented as a basis for several SA-based training approaches. The Situation Awareness Global Assessment Technique (SAGAT), an objective measure of pilot SA, is discussed as a means of evaluating the impact of training techniques on pilot SA.
