Until today were you aware that the stall warning could go away if a stall developed to the point that indicated airspeed dropped below 60KT?
I can't remember if I did as I'm not current on type, but I do remember that in the event of unreliable airspeed you'll could get a whole range of varied and contradictory warning signals and I'd place no faith in any of them. Pitch and power are the only things you can rely on until normality is resumed and getting a further stall warning in response to doing the
right thing, whilst damn confusing, shouldn't be unexpected.
