Abstract
A device for avoiding aircraft collisions with the ground determines the geographical location of the aircraft, and has a data base containing a description of safety altitudes for the geographical location. From the geographical location and the description of safety altitudes, the collision-avoidance device computes an air floor about the vertical of the aircraft. The altitude of the floor is greater than or equal to the safety altitudes about this vertical. In addition, the collision-avoidance device predicts the air position of the aircraft and compares this situation with the air floor. An alarm sounds when the aircraft passes beneath the floor.
