Systems and methods for alerting for an instrument landing system (ILS)

A method for alerting for an instrument landing system (ILS), the method comprising:

• at an on-board controller
• receiving an ILS signal by an aircraft performing an ILS landing operation on a runway;
• receiving traffic information;
• associating the ILS signal with stored ILS antenna information to thereby construct an ILS envelope having at least two dimensions;
• presenting a map showing the aircraft at a current location, and the runway;
• using the traffic information to monitor a location and movement of an intruder traffic;
• annunciating an ILS alert using an onboard display device upon predicting an infringement of the intruder traffic upon the ILS envelope during the ILS landing operation;
• and
• transmitting a notification to an entity other than the aircraft upon predicting the infringement of the intruder traffic upon the ILS envelope during the ILS landing operation.

A method for instrument landing system (ILS) alerting, the method comprising:

• at a controller onboard an aircraft performing an ILS landing operation on a runway,
• receiving an ILS localizer signal;
• 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 pre-programmed percentage;
• 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;
• receiving traffic information;
• 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;
• annunciating, on a display within the aircraft, an ILS alert upon predicting the infringement of the intruder traffic upon the ILS envelope;
• transmitting a notification to air traffic control or the intruder traffic upon predicting the infringement of the intruder traffic upon the ILS envelope or of the ownship on an ILS envelope of a traffic;
• and
• annunciating, on the display within the aircraft, a second ILS alert upon receiving a notification that the ownship will infringe an ILS envelope of a traffic.
