Abstract
A method and device optimize the vertical trajectory of an aircraft in flight along a predetermined approach trajectory. The method and device include the use of a calculator, which is structured to predict a predicted stabilization altitude at which the aircraft will reach a setpoint approach speed as a function of the current aircraft parameter values, a theoretical vertical trajectory, and predetermined models of aerodynamic efficiency of the aircraft. A comparator is structured to determine absolute value differences between the predicted stabilization altitude and the setpoint stabilization altitude and to compare the differences against a predetermined altitude threshold. A vertical trajectory determination unit is structured to determine an optimized vertical trajectory as a function of the current aircraft parameter values, auxiliary parameter values corresponding to a final approach axis, and the absolute value differences between the predicted stabilization altitude and the setpoint stabilization altitude.
