An aircraft terrain avoidance system include a device having a first unit knowing a profile of the terrain that is located at the front of the aircraft, a second unit for determining an avoidance trajectory, a third unit which is connected to the first and second units and used to verify if there is a terrain collision risk for the aircraft, a fourth unit for emitting an alarm signal in the event of detection of a collision risk by the third unit, at least one aircraft performance database relating to an avoidance maneuvering gradient which can be flown by the aircraft according to particular flight parameters, and a fifth unit for determining the effective values of the particular parameters during the flight of the aircraft. The third unit is formed such that it is possible to determine the avoidance trajectory according to information received from the database and the fifth unit.

The invention claimed is: 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; anda 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.
