Claim:
1. A method for determining the position of a component in a high lift system of an aircraft, the high lift system comprising a power control unit for providing rotational power by means of a transmission shaft; and actuator drive stations coupled with the power control unit and movable high lift surfaces; the method comprising the steps of: acquiring a first rotational position of a first position pick-off unit mechanically coupled with the power control unit by means of a first gear having a first gear ratio, acquiring at least one second rotational position of at least one second position pick-off unit mechanically coupled with a driven element in at least one drive station, determining a number of full rotations the first position pick-off unit has accomplished between a neutral position and an intended maximum number of rotations based on an associated number of angle sections of the at least one second position pick-off unit and a respective second rotational position, and multiplying the number of full rotations of the first position pick-off unit by 360° to create a resulting full rotations angle; and adding the resulting full rotations angle to the acquired first rotational position to acquire a position of a component in the high lift system.
