I think a point that constantly gets missed on this topic is, what caused the accident? Did the aircraft concerned at Camden crash because the mixture was cut? Or was it because the aeroplane was too low, or got below Vmca? Would the accident still have happened if the throttle was used in leiu of the mixture?
It's fine to say 'mixture cuts are bad' but is that the real reason of the accident?
I think more of concern is what happens AFTER the failure has been simulated, ie airspeed, height terrain clearence ahead etc etc.
