This Terrain Awareness and Warning System produces a new “Too Low Terrain” predictive alert of “Caution” type when the crew of the aircraft has the possibility of resolving a detected risk of collision with the terrain without interrupting the current maneuver to stabilize at a safety altitude by a leveling-off maneuver, without performing a vertical avoidance maneuver. To do this, it measures the ability of the airplane to avoid the terrain with a sufficient margin without performing a vertical avoidance maneuver, taking into account the location or locations of the penetration or penetrations of the terrain along an alert prober C as well as the capacity of the aircraft to level off knowing the flight conditions.

The invention claimed is: 1. A system aboard an aircraft, for preventing collisions with terrain, the system comprising:a collision risk detector for detecting a risk of collision of the terrain, by likening the risk of collision of the terrain after a predetermined period of forecasting to penetration of a cartographic representation of the terrain overflown stored in a database accessible from the aircraft into a deployment protection volume, the deployment protection volume being tied to the aircraft located with respect to the terrain overflown by means of an airborne locating equipment and oriented in a direction of progress of the aircraft, the deployment protection volume having a lower longitudinal profile modeling a potential trajectory comprising, as first part, an extrapolation of a trajectory followed by the aircraft, predicted on the basis of the flight information delivered by the flight equipments of the aircraft, as second part, a model of a terrain avoidance maneuver trajectory engaged over the forecast period, and a transition trajectory between the first part and the second part;a locating means for pinpointing one or more locations of the penetration of the cartographic representation of the terrain overflown on the lower longitudinal profile of the protection volume;an alert generator for producing one or more alert messages corresponding to the one or more locations of the penetration on request of the collision risk detector; anda particularization means for particularizing the alert messages emitted by the alert generator as a function of the one or more locations of the penetration.
