METHOD FOR DETERMINING THE BYPASS TRAJECTORIES FOR AN AIRCRAFT

The present invention relates to a method for determining trajectories for avoiding a potential danger zone (60) extending over a portion of a main trajectory (17) defined for an aircraft in an environment (12), the method comprising a preparation phase comprising determining, for each of the trajectory points sampling the trajectory of the aircraft on an image, minimum cost trajectories connecting said trajectory point to subsequent trajectory points taken in the direction of flight of the aircraft, the method further comprising an exploitation phase comprising determining trajectories for avoiding a potential danger zone (60) identified on the trajectory of the aircraft, as a function of the position of the aircraft determined in real time and the minimum cost trajectories determined.
