Claim 17:
18. An aircraft comprising:
a fuselage;
a landing gear assembly movable relative to the fuselage, the landing gear assembly having an extended position, the landing gear assembly including at least one linkage and an aperture extending through the at least one linkage, the landing gear assembly including a locking pin configured to be inserted into the aperture extending through the at least one linkage, which when inserted inhibits movement of the at least one linkage to establish a locked state of the landing gear assembly in the extended position;
wherein the landing gear assembly includes 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 landing gear assembly is in the extended position;
a landing gear monitoring and alerting system coupled to the landing gear assembly, the landing gear monitoring and alerting system including:
a magnetic sensor disposed proximate the aperture and configured to sense a magnetic response indicative of the locking pin being disposed within the aperture to establish the locked state of the landing gear assembly in the extended position, and the magnetic sensor being configured to generate a sensor output, prior to take-off of the aircraft, 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 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 landing gear assembly in the extended position.
