1. In an aircraft, including a display for receiving a display signal representative of terrain, a terrain data circuit comprising:
- an interface in communication with a radar system, a terrain database, and the display;
a display control circuit configured to process a first terrain data received from the radar system and to process a second terrain data received from the terrain database, the display control circuit further configured to generate a composite terrain image based on the first terrain data and the second terrain data; and
wherein the terrain data circuit is configured to provide the display signal representative of terrain based on the composite terrain image.

Abstract
A circuit for a display used on an aircraft causes the display to display a composite terrain image. The composite terrain image can be formed from first terrain data from a terrain database and second terrain data from a radar system. A display control circuit can generate a display signal for the composite terrain image. The display signal is received by the display. The composite terrain image can be viewed by a pilot.
