Abstract
An improvement over prior art aircraft instrument flight display systems for imaging on a bit-mapped display formed of a multiplicity of individually addressable pixels at locations throughout the display and actuatable to create images on the display, employs a common processor operatively connected between a video graphics processor and the display system input of a common set of aircraft and environmental sensor data— to provide both an integrity checking function and a graphics rendering function in which the integrity checking function can directly check the images generated by the graphics rendering function without the need for comparator hardware. Separate processors may also be employed instead of a common processor. The integrity checking function uses the input information for generating a pixel verification map for checking the display based on pixel color and location. The system can also check for pitch and roll accuracy as well as check the integrity of complex images using statistical detection.
