Abstract: The invention relates to a device including elements for automatically controlling an aircraft on the ground along the lateral axis, by a dissymmetrical use of the engines and/or brakes of the aircraft.

Abstract: Disclosed is a method and device for detecting lateral dissymmetry of an aircraft. A control parameter determination unit is used to determine a current value of a control parameter representative of all roll control surfaces of the aircraft, and a control parameter comparison unit is used to compare the determined current value with a predetermined reference value. A current deflection angle of a lateral stick of the aircraft is also determined, and the determined current deflection angle is compared with a predetermined angle value. A visual alarm signal is output, when the current value of the roll control surfaces of the aircraft is greater than a predetermined reference value and the lateral stick is at a deflection angle that is greater than a predetermined angle value.

Abstract: The invention relates to a device (1) that comprises means (2, 3, 4, 7) for automatically controlling an aircraft on the ground along the lateral axis, by a dissymmetrical use of the engines and/or brakes of the aircraft.

Abstract: Method and device for detecting a lateral dissymmetry of an aircraft. The detection device (1) comprises a means (7) for detecting a lateral dissymmetry, as a function of the cement value of a control parameter which is representative of the roll control surfaces of the aircraft, and of a current angle of deflection of a lateral stick of the aircraft.

Abstract: A system for automatically controlling lift augmentation devices of an aircraft, during a phase of take-off by the aircraft, includes a controllable actuator that shifts the lift-augmentation devices, and a control unit for generating control demands to control the actuator to bring the lift-augmentation devices into a defined position. The control unit further includes a detector that detects actual take-off by the air craft and, if appropriate, signals such detection to the control unit. At start of the take-off phase, the lift-augmentation device are brought into a first position, in which they are deployed. The control unit generates, at least when the detector signals the actual take-off, a control demand making it possible to bring the lift-augmentation devices into a second position, in which the lift-augmentation devices are retracted by comparison with the first position.
