This paper investigates a combinatorial optimization model for the flight conflict resolution problem. The collision avoidance problem is solved by changing the maneuvering dimensions of aircraft. In this paper, a new model called VAHC is proposed, in which aircrafts can not only change the velocity, heading angel and flight level but also return to the original route. Simulations demonstrate that (a) aircrafts could perform various maneuvers to avoid collisions in different cases; (b) aircrafts could return to the destination point or route in the flight plan; (c) the computation time is low enough to enable real-time execution.
