Patent ID: 8746614

Claim:
A method for actuating at least one positioning flap on each wing of an aircraft, which positioning flap is actuated by at least two flap coupling devices each comprising a flap actuator device, wherein a brake mechanism is arranged at least on one flap actuator device for each positioning flap such that activation of the brake mechanism causes a position of the respective flap actuator device to be locked, the method comprising the steps of: actuating each brake mechanism of the at least one positioning flap individually to cause the position of the respective flap actuator device to be locked, subsequently actuating the actuator device by means of a central drive motor, terminating actuation of the flap actuator device of the at least one positioning flap when a change in the position of the at least one positioning flap meets or exceeds a predetermined extent, and sensing an intervention state of the brake mechanism to determine whether the brake mechanism has caused the respective flap actuator device to be locked.
