With the presence of a cockpit display of traffic information (CDTI) that provides graphical airspace information, pilots can use a variety of conflict resolution maneuvers in response to how they perceive the conflict. Inconsistent preference findings from previous research on conflict resolution using CDTIs may be due to inherent ambiguities in 3-D displays and/or a limited range of conflict geometries. This paper describes a study that investigates conflict resolution maneuver preferences using three displays with different frames of reference and a wide range of conflict geometries. Results indicate that 3-D displays with interactive viewpoints reduced spatial ambiguities. The interactive 3-D displays produced a preference for vertical maneuvers over lateral similar to a 2-D coplanar display; however this preference was reversed under increased workload conditions for both 3-D displays. Pilots in all three display conditions showed a preference to maneuver vertically away from intruders, though this was eliminated (or reversed) as workload increased. The 2-D coplanar display induced a preference to laterally turn away from approaching intruders, which overwhelmed a trained “turn right” preference.
