Abstract:
1. A method of aiding the piloting of an aircraft flying at low altitude, wherein the following operations are carried out in an automatic and repetitive manner: a) determining at least one avoidance trajectory, at least over a predetermined distance ahead of the aircraft, said avoidance trajectory corresponding to a low altitude lateral trajectory and exhibiting at least one lateral turn; b) determining the profile of the terrain situated under this avoidance trajectory; c) determining at least one first limit slope corresponding to a slope that the aircraft must fly so as to be able to overfly said terrain over the whole of said predetermined distance along said avoidance trajectory depending on said profile of the terrain; and d) presenting to a pilot, on a viewing screen, at least one first characteristic sign which represents said first limit slope and which is associated with a slope scale, with which is also associated a symbol illustrating the ground speed vector of the aircraft.
