Abstract
Abstract. The study presented here aims to objectively measure the persistence in time of situation awareness (SA) in beyond-visual-range (BVR) situations. How long does a pilot maintain SA of air traffic communicated by radio? Overall, 63 participants (non-pilot and pilot trainees) had to position air traffic on a map based on radio calls. This study presents two new findings: (1) The spatial representation developed from audioverbal information has an anticipatory component and (2) this anticipation is time-bound. These results are encouraging for the development of an objective method measuring the factors that enhance or impair the anticipation of SA such as the division of attention. This study could lead to new aeronautical rules specifying how long a BVR situation can be held.
