The invention provides a sensor for determining when a latch for securing
an engine cowl on an aircraft is secured by detecting the proximity of a
latch hook and a latch pin. The sensor includes a resonant circuit
configured and adapted to transmit a status signal when the latch is in a
secured state. The sensor also includes a means for conveying status
information of the latch to a location remote from the latch based on the
status signal, the conveying means being operably connected to the
resonant circuit. The invention also provides a method of determining
when a latch is open or secured by detecting the proximity of a latch
hook and a latch pin.
