Patent ID: 11107361

Abstract:
Methods and systems for instrument landing system (ILS) alerting. The method may include: receiving an ILS localizer signal and traffic information; monitoring a signal-quality of the received ILS signal; annunciating on a display system onboard the aircraft an impending ILS auto-pilot disconnect alert when the signal-quality is determined to have decreased by more than a threshold; associating the ILS signal with stored ILS antenna information to thereby construct a three-dimensional ILS envelope with a point of origination at a location of an ILS localizer; presenting a map showing the aircraft at a current location, and the runway; and, using the traffic information to monitor a location and movement of an intruder traffic and predict an infringement of the intruder traffic on the ILS envelope. Responsive to the predicted infringement, the method may annunciate an ILS alert and transmit a notification to air traffic control or the intruder traffic.
