Abstract: The general field of the invention is, within the framework of terrain anti-collision systems for aircraft, the presentation on navigation aid displays of a simplified symbology suited to these critical situations. More precisely, the symbols comprise at least one arrow representing the direction of the ground speed vector with respect to the axis of the airplane and at least one set of straight segments representing the limit boundaries in plan view beyond which the aircraft will inevitably crash. Other symbols such as the indication of the instructed course supplement this symbology.

Abstract: The general field of the invention is, within the framework of terrain anti-collision systems for aircraft, the presentation in the Head-Up sight of a simplified symbology suited to these critical situations. It essentially comprises two identical vertical parallel bars of angular dimension substantially equal to the vertical angular field of the Head-Up visualization device, the positions of said bars in the horizontal plane being representative of the limits of the aircraft's clearance path and a horizontal bar disposed between the two vertical parallel bars so as to form an H, the position in the vertical plane of said horizontal bar being representative of the floor altitude that must be maintained by the aircraft. Other symbols supplement this piloting aid symbology.
