The proposal of the free flight mode has brought tremendous pressure to air traffic safety and put forward higher requirements on the technology of flight conflict resolution. The traditional velocity obstacle model is dedicated to solving potential flight conflicts on air routes. Therefore, this paper puts forward a three-dimensional heading release algorithm based on the ORCA. Based on the ellipsoidal flight protection area, we select the current position, velocity vector and heading of the aircraft as the feature variables. Firstly, qualitatively judge the conflict state, and then perform geometric derivation based on the speed obstacle method, and establish a conflict resolution model based on the minimum heading. The simulation results show that, without considering other conditions, this algorithm can effectively detect and resolve potential flight conflicts between two aircraft in three-dimensional space by adjusting the course.
