Collision avoidance device with reduced energy balance for aircraft, notably for avoiding collisions with the ground
First Claim
1. A collision avoidance path determining device on an aircraft, comprising:
- means for locating a position of the aircraft;
a database including safety altitudes corresponding to respective geographical locations;
means for constructing by computation a floor having a floor altitude value being greater than or equal to a respective one of said safety altitudes corresponding to said position of said aircraft, said means for constructing connected to said means for locating and said database;
means for predicting a predicted air position of said aircraft connected to said means for locating;
means for comparing the predicted air position of said aircraft with respect to said floor and for producing a comparison result, said means for comparing connected to said means for predicting and said means for constructing;
means for computing at least two avoidance paths considering a flight capacity, which includes a pulling-up and turning ability, of said aircraft when said comparison result indicates that a predicted air position of the aircraft is below said floor; and
means for determining an energy balance for respective of said at least two avoidance paths which consider said flight capacity of said aircraft.

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.
