ONE NEW FILLING ALGORITHM OF ATTITUDE INDICATOR IN AIRCRAFT COCKPIT

The filling of sky and ground region within the attitude indicator of an aircraft electronic flight instrument system （EFIS） is a work spending much time and typically achieved by special-purpose hardware．A novel rapid filling algorithm is presented which set up a boundary array and two horizon array，using two scanning ways，horizontally and vertically．The result of the algorithm emulated on PC has proved its certain application value．
