At the weekly Old Bold Pilots breakfast this morning, I asked the guy who was cognizant engineer on the stall warning computers for the DC-9 and MD-80. He was incredulous that the A330 Stall Warning would shut off below 60 knots airspeed. He said the AOA vanes on his planes would measure to about 50 degrees AOA.
I suspect the A330 vane mechanical limit is about 30 degrees, as I don't recall any greater AOA mentioned by BEA. Does anybody know?
