Let me reduce my original question to a specific situation. Suppose
you're flying in 60 degree weather, so no surface is contaminated with

was.

I don't know how to answer that without knowing more about the flight
condition and the stall margin. If the sudden pitch down was
associated with a loud noise I'd bail out!
