Abstract
A method for generating an optimum vertical trajectory of a flight trajectory of an aircraft in the descent/approach phase. The trajectory is defined between a current state and a target state of the aircraft on the basis of a speed profile of the aircraft as a function of a curvilinear abscissa of the aircraft along a flight plan. The profile corresponds to a transition between the current and target states and is broken down into successive segments each corresponding to a different aerodynamic configuration that the aircraft may adopt during the descent/approach phase. The method is based on defining a set of flight strategies, each strategy of the set being defined using for each segment of the speed profile flight parameters chosen randomly in ranges of values compatible with the aerodynamic configuration corresponding to that segment. Optimum vertical trajectory is generated on the basis of the strategy of the set.
