Abstract : The typical format of the cockpit display of traffic information (CDTI) has been the plan-view. Altitude has been represented numerically or by shape-encoding. It is possible that maneuver decisions are unfavorably biased and pilot workload increased by this kind of non-integrated format. As an alternative, a perspective display has been developed. This traffic display presents a more natural view of the airspace around an aircraft. Perspective depth cues provide a sense of volume. Reference metrics enhance separation judgements. Particular emphasis is placed on vertical separation. A flexible computer graphics program drives the dynamic vector graphics display in real-time, allowing interactive development of the optimum viewing geometry. The perspective and plan-view CDTI displays will be compared and further experiments will examine the ability of pilots to derive accurate mental models of spatial configurations from perspective displays, as a function of viewing geometry.
