For what it’s worth, my take on it is that PF’s references to “crazy speed” and his persistent holding nose up suggested to some that he confused mach buffet with pre- stall buffet, and high noise with high speed rather than high AoA, which kept him thinking all the way down that he had an overspeed problem. I have seen no other explanation which fits the facts.
I agree, which raises the question of attitude indication. Even a basic PPL knows that if the attitude and the power are correctly set, the speed will be correct. Especially the attitude! Why the hell did they ignore the extreme nose-high attitude indication?
And thank you Volume. There is indeed no such thing as stall speed - only stall AoA. I've many time stalled aeroplanes at high IAS, and flown them unstalled at zero IAS.
Had anyone taught these guys to fly?
