Patent ID: 8924047

Claim:
A method for determining a corrected approach trajectory for the approach of an aircraft to a landing runway, comprising: determining an energy of the aircraft E aero upon crossing the runway threshold on the basis of a predetermined approach trajectory and of a current state of the aircraft, said state comprising at least one current altitude, a current ground speed and a mass of the aircraft, and comparing the energy of the aircraft E aero upon crossing the runway threshold with a predetermined maximum energy E max , and when the energy of the aircraft E aero upon crossing the runway threshold is greater than the maximum energy E max , determining a corrected approach trajectory as a function of the difference between the energy of the aircraft E aero and the maximum energy E max ; and wherein determining the corrected approach trajectory further comprises: determining an energy to be reabsorbed E excess as a function of the energy of the aircraft E aero upon crossing the runway threshold and of the maximum energy E max , determining a trajectory length D corr making it possible to reabsorb the energy E excess as a function of performance of the aircraft, determining a corrected lateral trajectory as a function of the trajectory length D corr , and determining a corrected vertical trajectory as a function of the corrected lateral trajectory and of the performance of the aircraft.
