yeah Bloggs I agree with you. I guess Airbus thought an A330 wouldn't get that slow in the air!!
A simple thing to re program I would think.
It's still complicated though because as they fell toward the sea at <60 KIAS with a very high AOA they were in Alternate law and the speed should have had nothing to do with the stall warning activation. So it should still have sounded. Maybe the Flight Controls reverted to normal law after the probes thawed????
The more you read FCOM 1 the more you get confused!!
Time to close the book....
