Testing a Multidimensional Nonveridical Aircraft Collision Avoidance System, Experiments 3, 4

Veridical displays represent realistic scenes. State spaces are nonveridical displays representing ndimensional information. This research tests an aircraft separation maintenance display based on a nonveridical state space. In two experiments, licensed general aviation pilots flew flight scenarios, trying to deviate as little as possible from a pre-assigned course while still maintaining standard enroute separation from traffic. Flight performance using only a veridical cockpit display of traffic information with conflict alert capability was compared to performance augmented by a 4D nonveridical state space collision avoidance system. Results suggest that nonveridical display enhances operator performance on an aircraft separation maintenance task
