Abstract:
1. An aircraft terrain avoidance and alarm device, said device comprising: a first unit for determining the profile of the terrain at least in front of the aircraft; a second unit for determining an avoidance trajectory; a third unit connected to said first and second units, for verifying whether there exists a risk of collision of the terrain for the aircraft; and a fourth unit for issuing an alarm signal, in case of detection of the risk of collision by said third unit, wherein the device moreover comprises: at least one database of performance of the aircraft, relating to an avoidance maneuver slope flyable by the aircraft, as a function of particular flight parameters, said database comprising a plurality of values for said slope, that are representative on each occasion of different values of said flight parameters, and; a fifth unit for determining in the course of a flight of the aircraft effective values of said particular parameters, wherein said second unit is formed in such a way as to determine said avoidance trajectory, as a function of cues received respectively from said database and from said fifth unit.
