First Claim
Patent Images
1. A method of reducing unintentional incursions of an aircraft into zones of awareness associated with surfaces at an airport, the method comprising:
- retrieving a position of a reference point associated with a zone of awareness, the zone of awareness corresponding to a closed surface of the airport;
determining a current position of the aircraft;
calculating a distance between the current position of the aircraft and the reference point; and
generating and issuing an alert in response to the current position of the aircraft corresponding to the position of the reference point.

17. An alerting system for alerting an occupant of an aircraft on the ground that the aircraft is in or approaching a zone of awareness, comprising:
-
a storage device located on the aircraft, the storage device configured to store location information for a plurality of zones of awareness corresponding to closed surfaces at the airport, a map of the airport, and a position of at least one reference point for each of the plurality of zones of awareness; a positioning system located on the aircraft, the positioning system being configured to determine a current location of the aircraft; an alerting device located on the aircraft, the alerting device configured to issue an alert; and a processor located on the aircraft, the processor configured to calculate a distance between the current location of the aircraft and the at least one reference point, and configured to generate the alert in response to the current location of the aircraft corresponding to the position of the at least one reference point. - View Dependent Claims (18, 19, 20)

21. An alerting system for alerting an occupant of an aircraft on the ground that the aircraft is in or approaching a zone of awareness, comprising:
-
means for retrieving a position of a reference point associated with a zone of awareness, the zone of awareness corresponding to a closed surface of the airport; means for determining a current position of the aircraft; means for calculating a distance between the current position of the aircraft and the reference point; and means for generating and issuing an alert in response to the current position of the aircraft corresponding to the position of the reference point.

22. A method of reducing an unintentional incursion of a vehicle into a zone of awareness associated with surfaces over which the vehicle may traverse, the method comprising:
-
retrieving a position of a reference point associated with the zone of awareness, the zone of awareness corresponding to a closed surface over which the vehicle should not traverse; determining a current position of the aircraft; calculating a distance between the current position of the vehicle and the reference point; and generating and issuing an alert in response to the current position of the vehicle corresponding to the position of the reference point.
