So all airlines flying under FAA rules have to have the extra AoA gauge on their PFD? Didn't know that. There should be more than enough info about AoA flying in commercial jets then.
Remember, i wasn't talking about the normal 1.3g stall margin indication (yellow bar), nor about the stick shaker activation "eye brows" or the usual low speed warnings available on that aircraft (aural alert "AIRSPEED LOW", "BUFFET ALERT" on the CDU-scratchpad, yellow bar, red/black bar etc). I was talking about an additional indication of AoA which has a green band of values, not a line, for approach.
