Abstract:
1. A method for displaying traffic information on a moving map presented in a cockpit or flight deck of an airplane on a runway at an airport, comprising: (a) storing data defining a respective ground runway operating zone and a respective ground relevant runway zone for each runway at the airport, wherein each of said ground runway operating zones overlaps with and extends beyond a respective runway and each of said ground relevant runway zones overlaps with and extends beyond a respective ground runway operating zone; (b) receiving data indicative of the airplane's current location; (c) receiving data indicative of a respective current location of one or more other vehicles at the airport; (d) determining which of the other vehicles are ground traffic but not ground runway traffic and which of the other vehicles are ground runway traffic based on the current locations of the one or more other vehicles and the data defining the ground runway operating zones, the ground runway traffic being a subset of the ground traffic that includes traffic within said ground runway operating zones; (e) monitoring at least one of a speed, heading and track of the airplane; (f) when the airplane has a speed less than a threshold, displaying symbols representing the airplane and ground traffic at the airport on a moving map, each symbol representing a respective other vehicle of the ground traffic being positioned on said moving map to reflect at least one of respective location, heading and track of the respective other vehicle of the ground traffic relative to the location of the airplane; and (g) when the airplane reaches a speed greater than said threshold, ceasing display of the symbols representing vehicles of the ground traffic which are not ground runway traffic.
