IMPROVED AIRCRAFT INSTRUMENT FLIGHT DISPLAY SYSTEM WITH INTEGRITY OF GRAPHIC IMAGE

摘要

PROBLEM TO BE SOLVED: To provide an integrity checking function and the graphics rendering function to an aircraft instrument flight display system for imaging aircraft flight information by the bit map display. SOLUTION: A common processor 216 for operably connecting a common set of the aircraft and environmental sensor data 214 to a video graphics processor 206 is employed. The bit map display is individually addressible, and formed of a plurality of pixels. An integrity checking function 202 can directly check the image generated by the graphics rendering function 204. A separate processor can also be used in place of the common processor. The integrity checking function uses information input for generating the pixel verification map for checking the display based on the pixel color and position. The system can check the pitch and the roll accuracy in addition to the checking of a complicated image by using the statistical checking. COPYRIGHT: (C)2007,JPO&INPIT
