Abstract:
Methods and apparatus are provided for an azimuthal equidistant projection (AEP) aircraft navigational display. The apparatus comprises a generator providing the aircraft's current latitude and longitude (φ1,λ0), a user input for providing the desired map radius R, a display for presenting the navigational information, a map data source providing topographical information associated with geo-spatial coordinates, and a controller and memory coupled to the generator, data source, input and display for providing data transformations. Map data containing topographical information associated with each geo-spatial coordinate is obtained from the map data source for an area of approximately radius R from (φ1,λ0). Using the controller and memory, the geo-spatial coordinates are converted to AEP spatial coordinates so that the topographical information is now associated with such AEP spatial coordinates. The transformed map data is sent to the display to provide AEP navigational information on the display around (φ1,λ0).
