Claim 18:
19. An aircraft including an aircraft control surface element system, the aircraft control surface element system comprising:
an aircraft wing structure having a fixed part and a control surface element;
the control surface element is operably moveable relative to the fixed part;
a signal generator;
a signal transmitter coil electrically connected to the signal generator;
a signal detector;
a signal receiver coil electrically connected to the signal detector;
a signal transmission unit located in the control surface element;
the signal transmission unit comprising comprises a first coil and a second coil, the first coil being electrically connected to the second coil;
the signal transmitter coil, the signal transmission unit and the signal receiver coil forming at least a portion of an inductively coupled transmission line;
the signal generator operable to provide an electrical signal to the signal transmitter coil and the signal detector is configured to detect the electrical signal via the signal receiver coil;
the signal detector is configured to determine a condition of the control surface element by comparing a 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.
