Patent ID: 6922703

Claim:
A method for displaying navigational data associated with an aircraft on a display having a display coordinate system, said method comprising the steps of: providing one or more databases, each database including navigational data stored as geospatially organized data structures that include data representative of latitude and longitude coordinates; retrieving data from one or more of said databases; dynamically tiling the retrieved data onto one or more other data structures that represent display elements projected into the display coordinate system; culling the dynamically tiled data to a current display range, to thereby generate display into the display data structures; updating, in real-time, a projected display database that includes the generated display data structures and that substantially maintains correct projections of the dynamically tiled and culled data from latitude and longitude coordinates to Cartesian coordinates; modifying said display database in accordance with avionics data associated with said aircraft; and displaying said display database in accordance with said modifying step.
