Abstract
A method of determining the actual position of a control surface (27). The method comprises receiving a signal (34) representative of a required position of the control surface (27), repositioning the control surface (27) in response to the signal (34) by moving an actuator (26), measuring a secondary position indicator, calculating the actual position of the control surface (27) on the basis of the secondary position indicator and, comparing the actual position with the required position.

A method of determining an actual position of a control surface, the method comprising:
- receiving a signal indicating a required position of the control surface;
- repositioning the control surface in response to the signal by moving an actuator;
- measuring a secondary position indicator including providing a force measurement;
- calculating the actual position of the control surface based on the secondary position indicator;
- comparing the calculated actual position with the required position;
- and
- outputting the compared actual position.
