   I am forwarding this reply from John Knight at SPC -- AB

   Ada has not been used in any AIRBUS system that I know of that is in
production.   It has been used to develop a shadow AIRBUS flight control
system to evaluate Ada.   The system turned out very slow so they used a
faster CPU to ensure meeting deadlines (actually, 4 times faster).
