1. A method for aiding the management of the flight of an aircraft, according to which method there is envisaged an interface unit allowing a pilot to enter at least one of the following setpoints: a speed setpoint and an altitude setpoint, as well as means of automatic piloting which apply, in an automatic manner to said aircraft, setpoints thus entered, wherein: a) interface means are envisaged, moreover, allowing a pilot to generate a geographical constraint represented by a distance ahead of the aircraft, defining a position at which he wishes that a setpoint entered be attained; and b) an automatic thrust system of the aircraft and airbrakes of the aircraft are automatically servocontrolled, in a combined manner, so that the aircraft attains said setpoint entered, at the position defined by said geographical constraint.
