Abstract

A method, computing system and computer program product are provided to monitor compliance with a non-transgression zone between aircraft approach corridors, thereby facilitating simultaneous instrument approaches. In the context of a method, a predicted path of an aircraft is determined during a flight based upon at least a representation of a roll angle of the aircraft and a cross-track component of the velocity of the aircraft. The method also includes identifying an instance in which the predicted path of the aircraft during the flight intersects a non-transgression zone. The method further includes causing an alert to be issued in the instance in which the predicted path of the aircraft during the flight intersects the non-transgression zone.

Claims

1. A method for monitoring compliance with a non-transgression zone between aircraft approach corridors, the method comprising:

determining, with processing circuitry, a predicted path of an aircraft during a flight based upon at least a representation of a roll angle of the aircraft and a cross-track component of velocity of the aircraft;

identifying an instance in which the predicted path of the aircraft during the flight intersects the non-transgression zone; and

with the processing circuitry, interacting with a user interface to cause an alert to be issued in the instance in which the predicted path of the aircraft during the flight intersects the non-transgression zone, wherein interacting with the user interface comprises interacting with a display to cause a visual alert to be issued in the instance in which the predicted path of the aircraft during the flight intersects the non-transgression zone or interacting with one or more speakers to cause an audible alert to be issued in the instance in which the predicted path of the aircraft during the flight intersects the non-transgression zone.

2. A method according to claim 1 wherein determining the predicted path of the aircraft comprises determining the representation of the roll angle of the aircraft in real time, and wherein causing the alert to be issued comprises causing the alert to be issued in real time.

3. A method according to claim 1 wherein determining the predicted path is further based upon a current position and heading of the aircraft.

4. A method according to claim 1 wherein determining the predicted path comprises determining a turn rate and a turn radius based upon at least the representation of the roll angle of the aircraft and the cross-track component of the velocity of the aircraft.

5. A method according to claim 1 further comprising receiving the representation of the roll angle of the aircraft and the cross-track component of the velocity of the aircraft from at least one of an Enhanced Surveillance (EHS) surveillance transponder or from an Automatic Dependent Surveillance Broadcast (ADS-B) message.

6. A method according to claim 1 wherein identifying an instance in which the predicted path of the aircraft intersects the non-transgression zone comprises determining, prior to the aircraft reaching a largest cross track position error, whether corrective action has been initiated by the aircraft to avoid intersection with the non-transgression zone.

7. A method according to claim 1 wherein the predicted path of the aircraft is determined by the processing circuitry which is embodied by an air traffic control ground station, by an air traffic control radar system or as an auxiliary function to a display of the air traffic control radar system.

8. A computing system for monitoring compliance with a non-transgression zone between aircraft approach corridors, the computing system comprising processing circuitry configured to:
