Abstract
The present invention is a method for providing optimum multi-map overlay in a flight deck navigation display of an aircraft. The method includes outputting absolute terrain data to the navigation display for display by the navigation display. The method further includes receiving a threshold elevation input, the threshold elevation input including a threshold elevation. The method further includes receiving relative terrain data. The method further includes, when the aircraft is located below the threshold elevation, overlaying the relative terrain data onto the absolute terrain data based on the received threshold elevation input. Further, the absolute terrain data and the relative terrain data are concurrently displayed by the navigation display, the displayed relative terrain data being overlaid onto the displayed absolute terrain data.
