摘要
A flight control module for detecting anomalies in ILS localizer signals during landing of an aircraft is provided. The flight control module includes a communication interface and a processor coupled thereto. The communication interface is configured to receive inertial data, GPS data, and an ILS localizer deviation for the aircraft. The processor is configured to compute an inertial localizer deviation based on the inertial data and a GPS localizer deviation based on the GPS data. The processor is configured to compare the ILS localizer deviation to an average of the inertial localizer deviation and the GPS localizer deviation to detect a low-frequency anomaly in the ILS localizer deviation. The processor is configured to initiate a transition from controlling the aircraft based on the ILS localizer deviation to controlling the aircraft based on the inertial localizer deviation when the low-frequency anomaly is detected.
