Abstract: A method for optimizing the take-off parameters of an aircraft. The aircraft comprises a system for automatically controlling the high lift devices at the moment when the wheels of the aircraft leave the ground. The method comprises a step of selecting a first configuration of the high lift devices at the start of the take-off phase and a selection of an acceleration speed of the aircraft. The method is advantageous in that, on reception of an actual aircraft take-off detection signal, a control unit is configured to transmit a control command making it possible to bring the high lift devices into a second configuration, in which they are retracted relative to the first position, and consecutively accelerate the speed of the aircraft automatically to an acceleration speed entered by the pilot.
