Endsley's model
u The SA states framework above extends an older (but simpler), theoretical framework of SA, provided by Dr. Mica Endsley (1995b), which has historically been widely used. Endsley's model describes SA states and illustrates three stages or steps of SA formation: perception, comprehension, and projection.

u The first step in achieving SA is to perceive the status, attributes, and dynamics of relevant elements in the environment. Thus, Level 1 SA, the most basic level of SA, involves the processes of monitoring, cue detection, and simple recognition, which lead to an awareness of multiple situational elements (objects, events, people, systems, environmental factors) and their current states (locations, conditions, modes, actions).
