Automated Conflict Resolution for Air Traffic Control (AAC) Versions 1 and 2

A conflict resolution algorithm that can provide automated separation assurance for the next-generation air traffic control system has been developed. The algorithm generates resolution trajectories that can be sent to the aircraft from a ground-based system via a data link. With suitable reconfiguration, the algorithm can also be installed onboard aircraft to support airborne separation assurance. It handles the complete spectrum of conflict types encountered in en-route airspace, including ascents to cruise altitude and descents to arrival fixes. The resolution trajectories are patterned after changes to flight plans (route changes), altitude clearances, and speed profiles that controllers customarily issue to pilots in resolving conflicts.
