  • Azimuthal equidistant projection navigation display and method
    Patent number: 7933716
    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 (?1,?0), 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 (?1,?0). 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.
