Abstract
A display image for use in an aircraft is produced in response to receiving aircraft location, heading, altitude, and pitch data. The location and heading data are employed to access a topographical database and obtain terrain information for a region on the earth's surface ahead of the aircraft. A terrain image is produced from the terrain information and a non-linear pitch scale is superimposed over the terrain image. The non-linear pitch scale corresponds to the relationship of the aircraft pitch and the terrain image. Additional data designating other aircraft operational parameters, such as speed and altitude, are depicted by graphical objects. The terrain image, the non-linear pitch scale, and the graphical objects are combined into the display image. The terrain image and the non-linear pitch scale move in the display image in response to changes in the pitch of the aircraft.
