Abstract: A display generation system that is able to generate display signals for an underlay image with at least one embedded safety pattern and display images for an overlay image. The display generation system and method are able to determine whether there are any anomalies or graphical errors when an overlay display generated by the system or generated by some other system is displayed simultaneously with the underlay image with the embedded safety pattern. The display generation system uses the embedded safety pattern to detect the occurrence of anomalies in the simultaneous display and uses information from its own generated overlay image to detect graphical errors in the simultaneous display. Flight display systems for aircraft can use the display generation system and method of the present invention to display an underlay image depicting geographical scenery in the vicinity of the aircraft while on the ground, during takeoff or in flight.

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.

Abstract: A display generation system that is able to generate display signals for an underlay image with at least one embedded safety pattern and display images for an overlay image. The display generation system and method are able to determine whether there are any anomalies or graphical errors when an overlay display generated by the system or generated by some other system is displayed simultaneously with the underlay image with the embedded safety pattern. The display generation system uses the embedded safety pattern to detect the occurrence of anomalies in the simultaneous display and uses information from its own generated overlay image to detect graphical errors in the simultaneous display. Flight display systems for aircraft can use the display generation system and method of the present invention to display an underlay image depicting geographical scenery in the vicinity of the aircraft while on the ground, during takeoff or in flight.
