System for automatically controlling lift-augmentation devices of an aircraft during take-off

A system for automatically controlling lift augmentation devices of an aircraft, during a phase of take-off by the aircraft, said system comprising:

• controllable actuating means for shifting said lift-augmentation devices;
• and
• a control unit for generating control demands to control said actuating means to bring said lift-augmentation devices into a defined position, said control unit further including a first means for detecting actual take-off by the aircraft and, if appropriate, for signaling such detection to the control unit, and wherein, at start of the take-off phase, said lift-augmentation devices are brought into a first position, in which they are deployed, and wherein said control unit generates, at least when said first means signals the actual take-off, a control demand making it possible to bring said lift-augmentation devices into a second position, in which said lift-augmentation devices are retracted by comparison with said first position.
