Abstract
A device for determining the rotation angle of a shaft in an aircraft, the device having a shaft and a motor operable to rotate the shaft to operate a component and to detect first rotation data of the shaft. The device also includes a position pickup unit designed to detect second rotation data of the shaft, and a synchronization unit for synchronizing the first rotation data with the second rotation data.
Claims11
An aircraft having a device for determining the rotation angle of a shaft in the aircraft, the device comprising:
- a shaft designed for operating a component, the component selected from the group consisting of a brake flap, a landing flap, a landing slat, a rudder, an aileron and an elevator, the shaft having a first region and a second region,
- a motor which rotates the shaft to detect first rotation data corresponding to a first rotation angle of the first region of the shaft, the motor being designed to carry out said detection in an absolute manner;
- a position pickup unit designed to detect second rotation data corresponding to a second rotation angle of the second region of the shaft;
- and
- a synchronization unit designed to synchronize the first rotation data with the second rotation data.

A method for determining the rotation angle of a shaft in an aircraft, comprising the steps of:
- rotating the shaft by a motor;
- detecting first rotation data that corresponds to a first rotation angle of a first region of the shaft by the motor in an absolute manner;
- detecting second rotation data that corresponds to a second rotation angle of a second region of the shaft by a position pickup unit;
- and
- synchronizing the first rotation data with the second rotation data.
