A flight control module (402) for detecting anomalies in ILS localizer signals during landing of an aircraft (102) is provided. The flight control module (402) includes a communication interface (415) and a processor (438) coupled thereto. The communication interface (415) is configured to receive inertial data, GPS data, and an ILS localizer deviation (501) for the aircraft (102). The processor (438) is configured to compute an inertial localizer deviation (535) based on the inertial data and a GPS localizer deviation (606) based on the GPS data. The processor (438) is configured to compare the ILS localizer deviation (501) to an average of the inertial localizer deviation (535) and the GPS localizer deviation (606) to detect a low-frequency anomaly in the ILS localizer deviation (501). The processor (438) is configured to initiate a transition from controlling the aircraft (102) based on the ILS localizer deviation (501) to controlling the aircraft (102) based on the inertial localizer deviation (535) when the low-frequency anomaly is detected.
