Claim 19:
20. A method for determining a condition of one or more aircraft moveable elements, each of the one or more aircraft moveable elements having installed thereon a respective moveable element signal transmission unit, each moveable element signal transmission unit comprising a first signal transmission unit coil and a second signal transmission unit coil, the first signal transmission unit coil being electrically connected to the second signal transmission unit coil, wherein the method comprises the steps of:
generating, using a signal generator, an electrical signal;
providing the electrical signal from the signal generator to a signal transmitter coil;
transmitting the electrical signal from the signal generator to a signal receiver coil via an inductively coupled transmission line formed from the signal transmitter coil, the one or more moveable element signal transmission units and the signal receiver coil;
providing the electrical signal from the signal receiver coil to a signal detector;
detecting, using the signal detector, the electrical signal;
determining, using the signal detector, a condition of one or more moveable elements by comparing the detected electrical signal to a predetermined signal characteristic; and
the predetermined signal characteristic including at least one of: a peak voltage; a peak root mean squared voltage; a voltage profile over time; and an original phase of the electric signal produced by the signal generator.
