DISPOSITIF DE VISUALISATION POUR AERONEF COMPRENANT DES MOYENS D'AFFICHAGE D'UNE SYMBOLOGIE DE NAVIGATION DEDIEE A L'EVITEMENT D'OBSTACLES.

摘要

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.
