1. An aircraft moveable element monitoring system comprising:
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;
one or more moveable element signal transmission units 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;
the one or more moveable element signal transmission units configured to be installed on a respective moveable element of an aircraft;
the signal transmitter coil, the one or more moveable element signal transmission units and the signal receiver coil forming an inductively coupled transmission line;
the signal generator configured to provide an electrical signal to the signal transmitter coil and the signal detector configured to detect the electrical signal via the signal receiver coil;
the signal detector configured to determine a condition of the 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.
