Perspective and predictive information in the cockpit as a target acquisition aid
other
In two flight simulation experiments, the potential benefits of 3D perspective) radar displays for situational awareness support were investigated. In the experimental set-up, a target acquisition task was employed in which subjects, flying a fighter aircraft, were required to locate a target that suddenly appeared. Then, a target interception had to be performed as quickly as possible. Pilot task performance was measured in terms of target acquisition time and mental workload. Results of the first experiment show that perspective radar information considerably improved task performance compared to a (2D) plan-view radar, in particular with inside-out motion reference. Results of the second experiment show that additional predictive information on the target's flight path, based on linear extrapolation of relative velocity components of aircraft and target, did not firrther enhance pilot performance. Apparently, the perspective radar display used in the first experiment provided adequate spatial awareness and allowed proper anticipation, so that optimal acquisition performance was obtained. There was even a tendency that the additional predictive information deteriorated pilot's interpretation (display clutter). Experimental results and implications of the use of perspective radar displays in the cockpit are discussed.
