ABSTRACT:
The present application describes a monitoring circuit for an aircraft. The monitoring circuit comprises an inductive system, wherein the inductive system comprises a multitude of air core inductors and capacitors. Depending on the distance between a target and the inductive system the frequency response of the inductive system is changed. The change in the frequency response is detected and displayed in a display unit. The monitoring circuit can be used to improve door monitoring in an aircraft.
