Abstract
Disclosed is a collision avoidance device with reduced energy balance for aircraft, in particular for avoiding collision with the ground. This device comprises means for the geographical localization of the aircraft, a database containing a description of safety altitudes, means for the construction of an air floor about the vertical passing through the aircraft, the altitude of the floor being greater than or equal to the safety altitudes about this vertical, means for predicting the air position of the aircraft, means to compare this position with the air floor, means for the computation of avoidance paths and means to determine the energy balance of each of the computed paths. Application to equipment for aircraft, notably for civilian airliners.
