Future airspace operations will allow flight crews to plan and fly their own preferred route and time of arrival without much intervention from air traffic control. Thereby, pilots will become more responsible for planning their own route while maintaining safe separations from traffic and/or terrain. This demands for strategic and tactical planning tools that supports pilots in these tasks. The work in this paper focuses on supporting the airborne separation assurance task in the vertical plane by means of portraying traffic and terrain conflict zones onto an enhanced Vertical Situation Display. In a simulator evaluation the experimental display was compared to a baseline display that only showed a terrain profile and intruder aircraft location relative to ownship. The experiment results revealed that although the overlays decreased pilot workload, and resulted in slightly less traffic conflicts, decision-making and conflict awareness did not significantly improve.
