Abstract:
1. A method of aiding navigation for aircraft comprises: rendering on a display a navigation map formulated on the basis of: wherein the map of vertical margins is generated on the basis of a map of curvilinear distances obtained by applying a propagation distance transform based upon the current position of the aircraft, non-maneuverable zones to be circumvented, and the preset vertical flight profile in compliance with the vertical margin threshold; wherein the non-maneuverable zones are situated in proximity to the current position of the aircraft, are determined as a function of inertia, heading, course, and speed of the aircraft, as well as the performance of the aircraft in case of engine failure, and wherein the non-maneuverable zones are delimited, to the right and to the left of the current position of the aircraft, by a ground projection of the tightest possible lateral turning trajectories that are acceptable for the aircraft having regard to an exceptional situation of engine failure and a minimum of aircraft occupant comfort.
