Numpty question - does the 777 have an AOA gauge and if so, what does it present to the pilot?
AA does on the 777 and 737NG.
DL does on one, or both, of the 777 and 737NG's.
Guys don't use them for normal ops. Airspeed tape, with Vapp bug, amber foot, red/black stall tape and flap limit speed, has more information.
