Method for testing a component in a high lift system of an aircraft |
摘要 |
A method for testing a component in a high lift system of an aircraft comprises the steps of activating a brake coupled with at least one hydraulic motor, commanding a rotation of the at least one hydraulic motor for a predetermined period of time, wherein the brake remains activated, acquiring a sensor output of a motion sensor coupled with a central power control unit for moving a high lift surface during the commanded rotation of the at least one hydraulic motor, determining a motion of the power control unit from the acquired sensor output, comparing the determined motion with a predetermined threshold value, and generating a brake indication signal if the determined motion exceeds the predetermined motion threshold value. |

1. A method for testing a component in a high lift system of an aircraft, the high lift system comprising a central power control unit for moving high lift surfaces arranged at a wing through providing rotational power by means of a transmission shaft to a plurality of drive stations coupled with the high lift surfaces; which power control unit comprises at least one hydraulic motor coupled with a selectively activatable brake; the method comprising:
activating the brake, commanding a rotation of the at least one hydraulic motor for a predetermined period of time, wherein the brake remains activated, acquiring a sensor output of a motion sensor coupled with the central power control unit during the commanded rotation of the at least one hydraulic motor, determining a motion of the power control unit from the acquired sensor output, comparing the determined motion with a predetermined threshold value, and generating a brake indication signal of the determined motion exceeds the predetermined motion threshold value. |
