Tried it in the simulator today. Aux drive shaft failure at 90 pecent N1. The engine simply flames out with no fuss and bother. The N2 falls instantly to zero indication. The vibration is less than that during take off. Normal load shedding occurs. Clearly no severe damage indications.
I find it a bit worriesome to see how people seem to think that the behaviour of the simulator with a programmed failure of somekind is somehow a valid indication to forecast how an actual airplane will behave in real life.
Guys, it is exactly the other way around. You have real life. And then there are the simulators that trie to simulate as accurately as possible, but still SIMULATE, what will happen so we can train that.
There is no value whatsoever in the behaviour of a simulator extrapolated to real life. I even think it is dangerous to assume there is.
In real life, chances are very good that things will go just that little bit differently.
See what happened with Qantas recently. I don`t think that scenario was programmed in the simulator. Real life always bites you in the butt if you don`t expect it.
