Abstract
Situation Awareness (SA) assessment is a developing process that uses a variety of assessment techniques. Beginning with assessment methods developed for aircraft flight simulation, the study of SA has progressed to other areas, and this has broadened the domain into areas where faster response times and greater diagnosticity are desired. As a consequence of this maturation process, numerous SA rating scale methods have been proposed. It is posited that situation awareness is too complex a subject to rely exclusively on any type of numeric rating system, and it is argued that a return to a definitional approach to measuring SA is indicated. A method is proposed that emphasizes the three primary elements of SA (Perception, Comprehension and Projection) and this method should also increase diagnostic capability.
