An aircraft comprising: a landing gear assembly including at least one linkage with an aperture extending through the at least one linkage when the landing gear assembly is extended; and a landing gear monitoring and alerting system, comprising: a locking pin configured to be inserted into the aperture when the landing gear assembly is extended, which when inserted inhibits movement of the at least one linkage to establish a locked state of the extended landing gear assembly; 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 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 indicative of the locking pin being disposed within the aperture, and the communication module being configured to responsively transmit a signal indicative of the locking pin being disposed within the aperture, establishing the locked state of the extended landing gear assembly. a landing gear assembly including at least one linkage with an aperture extending through the at least one linkage when the landing gear assembly is extended; and a landing gear monitoring and alerting system, comprising: a locking pin configured to be inserted into the aperture when the landing gear assembly is extended, which when inserted inhibits movement of the at least one linkage to establish a locked state of the extended landing gear assembly; 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 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 indicative of the locking pin being disposed within the aperture, and the communication module being configured to responsively transmit a signal indicative of the locking pin being disposed within the aperture, establishing the locked state of the extended landing gear assembly. a locking pin configured to be inserted into the aperture when the landing gear assembly is extended, which when inserted inhibits movement of the at least one linkage to establish a locked state of the extended landing gear assembly; 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 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 indicative of the locking pin being disposed within the aperture, and the communication module being configured to responsively transmit a signal indicative of the locking pin being disposed within the aperture, establishing the locked state of the extended landing gear assembly.
