摘要

The general field of the invention is, in the context of the systems of - collision with the ground for aircraft, the presentation in the head-up display of a symbology simplified adapted to these critical situations. It essentially comprises two parallel bars identical vertical (102a, 102b) of the angular dimension substantially equal to the vertical angular field of the head-up display, the positions of said bars in the horizontal plane being representative of the limits of the path of the release of the aircraft and a horizontal bar (103a) disposed between the two parallel bars vertical so as to form an h, the position in the vertical plane of said horizontal bar being representative of the floor altitude that is to maintain the aircraft. Other symbols (100, 201, 202, 203, 204) complete this symbology for assisting the piloting.
