Influence of a Perspective Cockpit Traffic Display Format on Pilot Avoidance Maneuvers,
Abstract
Laboratory experiments have examined perspective projections of Cockpit Displays of Traffic Information (CDTI) on CRTs as a means of presenting vertical separation information to airline pilots. Ten airline pilots served as subjects in an experiment comparing the perspective projection with plan-view projections of the same air traffic situations. Comparison of the pilots' avoidance maneuvers made when using the perspective display with those made while using more the conventional plan-view display has shown that pilots maneuvered somewhat earlier with perspective displays. When they did maneuver with the perspective display, they maneuvered more frequently in the vertical dimension. Thus, a previously observed bias to maneuver horizontally was probably not based on the procedural reasons that were given by the pilots. That bias thus probably reflected the poorer presentation of vertical separation on previously used plan-view traffic displays. Tabulation of the outcomes of the avoidance decisions made by pilots using both perspective and plan-view displays showed fewer unsuccessful maneuvers and fewer maneuvers producing spacing violations with the perspective format.
