The purpose of this experiment is to investigate performance on a perspective tactical display as compared with a plan-view display. The perspective display represents information about altitude and attitude directly, whereas the plan-view display necessitates the use of an auxiliary information panel to show this information. Participants performed tasks requiring them to identify all descending aircraft displayed, with two different numbers of descending aircraft. Time to completion and partial results were collected automatically for each participant in a 2x2 within-subjects design. The experiment revealed strengths and weaknesses of both types of displays: plan-view was more effective for finding every descending aircraft, while perspective view was better for quickly identifying most of the descending aircraft.
