1. I should have been more pedantic and write KEAS instead of KIAS, to exclude the case of speed indication loss. It would make it more understandable to those who are learning aerodynamics through Google search.
2. I should have been more pedantic and make clear that my response was referring to stalled phase of AF447 flight (at that time, indication below 60kt was realistic and not result of clogged pitots), as was the Ian W's claim to which I've responded.
3. Since you mention interim 3, it has some other pages, like 29. At 2:10:09 and 2:10:13, computed airspeed is still a mess, yet the stall warning goes off as the aeroplane is jerked into climb!
Where does that leave the theory that unreliable airspeed alone will rob A330 of stall warning?

Let me see.... you pull the stick and are shouted at that you are about to stall for 54 seconds, at least two (and probably three) airspeeds are agreeing and going down, eventually pitch is positive yet the altimeter is unwinding. Somehow you conclude that all those are not clues enough that you're stalled. I am at loss to explain this. Would you, please?
