I'll ask the Airbus drivers a question that has come up before: would an AoA gage (which is apparently not common in any airliner design, and for most regimes of flight a supplemental scan item) be a useful addition to the flying display?
LW50:
(Disclaimer: This is not an A versus B comment, or an AF447 comment, hopefully just a politely informative one in response to a question. This is a tough crowd.)
Most, if not all, Boeing 737 NG’s (not sure about BBJ’s or special orders) have an AOA display directly visible on both the PFD and in the HUD. Is it useful? Depends on the guy driving.
