Claim 9:
10. A method of operating a landing gear monitoring and alerting system of an aircraft, the method comprising:
monitoring a magnetic field proximate an aperture of a landing gear assembly, the landing gear assembly including at least one linkage, the aperture extending through the at least one linkage, the landing gear assembly including a locking pin configured to be inserted into the aperture when the landing gear assembly is in an extended position to inhibit movement of the at least one linkage and establish a locked state of the landing gear assembly in the extended position;
actuating a locking actuating rod which drives a locking hook to hook around the locking pin to lock the locking pin in place to inhibit movement of the at least one linkage which locks the landing gear assembly is in the extended position;
sensing a magnetic response indicative of the locking pin being disposed within the aperture, prior to take-off of the aircraft, to establish the locked state of the landing gear assembly in the extended position; and
transmitting a signal, prior to take-off of the aircraft, indicative of the locking pin being inserted into the aperture, establishing the locked state of the landing gear assembly in response to sensing the 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.
