PROBLEM TO BE SOLVED: To provide a method for determining a state of a component in a high lift system of an aircraft.SOLUTION: A high lift system 2 comprises: a central power control unit 4 for providing rotational power by means of a transmission shaft 8, 10; and drive stations 12 coupled with the power control unit 4 and movable high lift surfaces 18. A method for determining a state of a component in the high lift system 2, comprises the steps of: acquiring in an extended position in flight at least one first position of a first position pick-off unit 20 coupled with the component, which is mechanically coupled with one of the high lift surfaces 18, and which is coupled with one of the drive stations 12; acquiring on ground at least one second position of the first position pick-off unit 20 in the extended position; determining a deviation between a measure based on the first position and an associated measure based on the second position of the first position pick-off unit 20 between ground and flight; determining whether the deviation exceeds a predetermined threshold; and generating a signal indicating an abnormal state of the component when the deviation exceeds the predetermined threshold.SELECTED DRAWING: Figure 1
【課題】航空機の高揚力装置の部材の状態を判定する方法を提供する。【解決手段】高揚力装置2は、伝動シャフト8、10を用いて回転動力を供給する中央電力制御部4と、電力制御部4及び可動高揚力面18に連結している駆動ステーション12を備えている。高揚力面18のうちの1つと機械的に連結しかつ駆動ステーション12のうちの1つとも連結している部材と連結している第1位置ピックオフ部20の少なくとも1つの第1位置を、飛行中に伸張位置にて取得するステップと、第1位置ピックオフ部20の少なくとも1つの第2位置を、地上において伸張位置にて取得するステップと、第1位置ピックオフ部20の第1位置に基づく測定値と第2位置に基づく関連測定値の地上及び飛行中の間の偏差を判定するステップと、偏差が予め定められた閾値を超えるかどうかを判定するステップと、偏差が閾値を超える場合に、部材の異常を示す信号を生成するステップを含む。【選択図】図1
