It does of course exist, just the probability of you running into it or have an accident as a result is slim to naught.
respectfully disagree with that - the chances of encountering it have reduced as disc loadings on modern helicopters have increased as a result of more powerful engines and smaller, more efficient rotors but the threat is still there.
Absolutely, the lack of talent is what puts you in the ballpark but at some point aerodynamics do have to have their say - whether you choose to believe it or not.
Yes, not enough power is more often than not the reason for such mishaps but if he applies enough power and still goes down without Nr decay, what will you call it then?
if it's not really a factor., why are so many simulators hard wired to give you the red screen of death when you hit the parameters?
