Abstract

Abstract: Trajectory Based Operation (TBO) is the future vision of air traffic management, and provides efficiency, capacity and safety benefits by managing aircraft trajectories cooperatively. According to air traffic operational characteristic of responsibility airspace division, this paper presents a conflict-free trajectory generation for pre-tactical phase in TBO environment. Considering the traffic flow distribution and flight conflict, a detailed conflict-free trajectory planning algorithm based on waypoint trajectory constraint is developed. Some simulation results based on typical operational data are carried out to show the feasibility of proposed method. This work is of great significance to the development of trajectory management and decision tools to support TBO.
