Abstract:

Transferring part of the responsibility for separation maintenance from the controller to the pilot during the route cruise phase can reduce the control load and improve the efficiency of airspace safe operation. For the new generation of distributed air traffic control mode, the own aircraft uses the target aircraft with potential conflict as the target aircraft for separation control based on the time-to-go of the intersection point, and builds an autonomous separation control model based on the specified separation values of time and space in the cross-conflict, respectively. Taking the calibrated airspeed of aircraft's maneuvering flight as the autonomous separation control strategy of the aircraft, the purpose of effectively controlling the separation between two aircrafts is achieved by controlling the calibrated airspeed of the own aircraft. Finally, a horizontal cross-conflict scenario is set up to conduct a simulation comparison experiment. Simulation results show the effectiveness and practicability of the separation control strategy in this paper for distributed autonomous separation maintenance.

Key words: air traffic management, autonomous separation control, horizontal cross-conflict, time-to-go of conflict point
