Claim 0:
1. A landing gear monitoring and alerting system for an aircraft, the landing gear monitoring and alerting system comprising:
a locking pin configured to be inserted into an aperture extending through at least one linkage of an extended landing gear assembly, which when inserted inhibits movement of the at least one linkage to establish a locked state of the extended landing gear assembly;
a locking hook and a locking actuating rod coupled to the locking hook and the at least one linkage, wherein actuation of the locking actuating rod drives movement of the locking hook to hook around the locking pin to lock the locking pin in the aperture which inhibits movement of the at least one linkage and locks the extended landing gear assembly in the locked state;
a magnetic sensor disposed proximate the aperture and configured to sense a magnetic response, prior to take-off of the aircraft, indicative of the locking pin being disposed within the aperture to establish the locked state of the extended landing gear assembly, and the magnetic sensor being configured to generate a sensor output indicative of the locking pin being disposed within the aperture; and
a communication module having a transmitter being coupled to the magnetic sensor so as to receive the sensor output, prior to take-off of the aircraft, indicative of the locking pin being disposed within the aperture, and the communication module being configured to responsively transmit a signal, prior to take-off of the aircraft, indicative of the locking pin being disposed within the aperture, establishing the locked state of the extended landing gear assembly.
