Abstract: A method for determining a state of a component in a high lift system of an aircraft comprises the steps of extending at least one high lift surface, which is coupled with two drive struts, wherein at least one of the two drive struts is a load sensing drive strut, to a first extended position, acquiring a first load sensed by a load sensing drive strut associated with the at least one high lift surface at a first flight state having a first speed, comparing the first load with a known nominal load for the first extended position and the first flight state under consideration of a predetermined threshold, and producing an alarm signal in case the acquired load differs from the nominal load including the predetermined threshold.

Abstract: A method for determining a state of a component in a high lift system of an aircraft is proposed, the high lift system comprising a central power control unit for providing rotational power by means of a transmission shaft; and drive stations coupled with the power control unit and movable high lift surfaces.

Abstract: A method for determining a state of a component in a high lift system of an aircraft, the high lift system including a central power control unit for providing rotational power by a transmission shaft; and drive stations coupled with the power control unit and movable high lift surfaces, includes acquiring in an extended position in flight a first position of a first position pick-off unit coupled with the component, mechanically coupled with a high lift surface, and coupled with a drive station; acquiring in flight a second position of a second position pick-off unit arranged in or at the central power control unit in the extended position; determining a deviation between a first measure based on the first position and a second measure based on the second position; determining, whether the deviation exceeds a predetermined threshold; and if so, generating a signal indicating an abnormal state of the component.
