But anyway, could somebody please post the reference if it exists? Would really appreciate it.
I am not rated for the A330, however I can recall no mention of any 60 knot figure as it relates to stall warning indications going missing during the whole of my A320 course. A quick review of verbose notes also shows no reference to an airspeed-based cutout of the cricket and/or voice warnings.
Since the warnings (and condition) are generally based on AOA, I never imagined speed data thresholds played into the logic until now.
