A present novel and non-trivial system, apparatus, and method for presenting information to the pilot on an aircraft display unit employed in a synthetic vision system (“SVS”), an enhanced vision system (“EVS”), or combined system. Information regarding the locations of visible and invisible objects
A present novel and non-trivial system, apparatus, and method for presenting information to the pilot on an aircraft display unit employed in a synthetic vision system (“SVS”), an enhanced vision system (“EVS”), or combined system. Information regarding the locations of visible and invisible objects related to aviation such as airports, navigation aids and facilities, and airspace are provided by location markers. Data representative of the terrain and location of objects depicted in a scene outside the aircraft are retrieved from one or more data sources. An image generating processor generates an image data set representative of a three-dimensional perspective view of a scene outside the aircraft, wherein the image data set is determined as a function of the terrain data and location marker data associated with the location data. The image data set may be provided to a Head-Down Display unit, a Head-Up Display unit, or both.
