Abstract:
A process for aiding the aerial navigation of an aircraft, comprising the following steps:a) receiving, on board the aircraft, status indications representing its position and its velocity vector,b) storing in a work memory a three-dimensional representation of the relief of the terrain region overflown by the aircraft,c) defining, as a function of the said status indications, an exploration sector referred to the aircraft, and calculating in this sector a contour as a function of the intersection of this sector with the relief, andd) displaying said contour, characterized in that step c) comprises the following sub-steps:c1) calculating auxiliary velocity vectors by shifting the velocity vector of the aircraft according to a chosen law of angular scanning, andc2) defining said exploration sector by a sheet of trajectory lines starting from said velocity vector and from said auxiliary velocity vectors.
