Abstract:
1. A method for optimizing vertical trajectory of an aircraft in flight along a predetermined approach trajectory to provide a stabilized final approach defined by a setpoint approach speed and a setpoint stabilization altitude (Zs) on said predetermined approach trajectory, said method comprising the steps of: A/ determining, by an information determination unit, current aircraft parameter values, including a theoretical vertical trajectory for the predetermined approach trajectory; B/ predicting, by a calculator, a predicted stabilization altitude at which the aircraft will reach said setpoint approach speed as a function of: C/ calculating, by a comparator, absolute value differences between the predicted stabilization altitude and the setpoint stabilization altitude (Zs) and comparing, by the comparator, the calculated absolute value differences with a predetermined altitude threshold; D/ determining, by a vertical trajectory determination unit, an optimized vertical trajectory (TO) as a function of: E/ transmitting said optimized vertical trajectory (TO) to a guiding unit structured to guide the aircraft.
