Abstract
A flight plan for a tactical flight of an aircraft is generated using first input data including initial weight and initial loading of the aircraft, meteorological data, points of transit of the flight plan and at least one optimization criterion. With the aid of the input data and by implementing a prediction function and an optimization function, a flight profile of the flight plan is determined. The profile includes for each point of transit of the flight plan, a plurality of predictive information items and, between two successive points of transit of the flight plan, optimized parameters. The flight plan is presented on a display screen. A second input allows an operator to enter, for each tactical event of the tactical flight, a variation of at least one parameter which is modified by this tactical event at a particular point of variation of the flight plan. The flight profile is determined using each parameter variation which is taken into account at the corresponding point of variation.
