ABSTRACT:
A device for aiding aerial navigation, carried on board an aircraft, receives on an input, status indications representing its spatial position and its velocity vector, and stores a 3D representation of the relief overflown. It comprises processing define, as a function of the status indications, an exploration sector referred to the aircraft, and calculate in this sector a contour as a function of the intersection of this sector with the relief, with a view to the displaying thereof. The sector is defined by a sheet of trajectory lines obtained on the basis of the velocity vector and of auxiliary vectors calculated by shifting the velocity vector of the aircraft according to a chosen angular scanning law.
