762: And which sim was that (Rn or RAF). I can assure you that once a tail rotor DRIVE failure is presumed - then the engines are chopped in a Sea King (unless you go for range). However in a Tail rotor CONTROL failure situation the engines are NOT chopped. Is that what you meant?
In other helos, especially those with large side tail surfaces like the fan in fin, fenestron types and even the Twin Star, there are other options rather than chopping the engine(s) during a total tail rotor failure.
Secondly one has to be in a position to continue flying after a tail rotor failure, if the tail rotor has gone walkabout from the a/c and the C of G goes out of limits rendering the a/c unflyable
But we digress from this thread - apologies.
