What would you do if the airspeed was increasing at the same time the stall warning was sounding, and the PFD had rapid fluctuations?

Absolutely, positively put the nose down & chopped the power. - The aircraft is falling out of the sky - thats why the airspeed is increasing.

I damn near pinked my first exam for not doing that quickly enough, & although I agree with you that nothing is as it seems on the ground, they did have 4 minutes to correct and you know thats a very long time.

Wrong. The airspeed was increasing because the pitot system failed. The instruments were giving conflicting information.

"Put the nose down" is never the issue - the issue is angle of attack, and as every jet pilot knows, angle of attack is not the same thing as pitch in relation to the horizon. Unloading the wing of an airliner is not the same as a Cessna.

If you see your climb indicator showing that you are sinking at -10,000 feet/min would you pull the nose up thinking you might be in a dive?
