Abstract

The invention relates to a method that allows an aircraft to follow a lateral trajectory with a specified safety level. The method consists in determining, from at least one calculated safety distance, a 3D corridor around a predicted trajectory of the aircraft. If the safety corridor comes into conflict with at least one obstacle from a terrain and obstacle database, the vertical flight profile of the aircraft is modified in order to increase the altitude of the aircraft and avoid obstacles having a constant lateral trajectory.
