Airport map display system and data interchange method
First Claim
1. A method of airport map data interchange in an aircraft comprising the steps of:
- obtaining the coordinates of a reference location;
obtaining the coordinates of an airport structure;
communicating said reference location to a display device;
computing relative structure coordinates of the airport structure relative to said reference location;
scaling the relative structure coordinates;
converting the scaled relative structure coordinates to absolute position coordinates; and
communicating said structure coordinates to said display device.

Abstract
An airport map display system provides situational awareness to a pilot of an airport'"'"'s runways, taxiways, and other features relative to the pilot'"'"'s aircraft. Data representative of an airport map is translated and communicated between aircraft systems using a data interchange method that facilitates efficient throughput of information used to represent an airport map. In addition, data representative of taxi routes, modified taxi routes, and current position of the aircraft at the airport are also translated and communicated using a compact data interchange method. Airport map data is scaled so that it is compatible with display systems previously incompatible with displaying some airport maps. Aircraft equipped with raster displays are manipulated to display map symbology by redefining existing vector group labels. For retrofit applications, the airport map display system is activated when a preexisting input (e.g., an “ARPT” button) is activated when a taxi-related page is active.
