摘要：
The invention concerns the prevention of the risks of collision of an aircraft with the terrain, in particular so as to provide protection against these risks during the final approach phase up to the runway threshold. The invention effectively combines two evaluations of complementary risks. A first risk consists in determining, on the basis of an item of information regarding trajectory of an avoidance manoeuvre of the aircraft on the basis of a current position of the aircraft, whether the trajectory of the avoidance manoeuvre enters a protection volume dependent on an overflown terrain. A second risk consists in determining whether a trajectory of the aircraft, extrapolated from the current position of the aircraft, intersects the ground before the runway threshold. An alert will not be generated unless the two determinations are positive.
