The only aircraft I have flown with AOA is the Citation 500. It worked well for LRC in still air and on approach. I wish it was installed in airliners but it isn't. If they had AOA on Air France with a pitot/static failure it might have helped if they were familiar with it. I haven't missed it in the last 30 years but AOA was a nice back up. Don't expect it to ever be an airline display. Anybody know how the search is going? Are any of our advanced submarines searching the area?
