On the S92 a FADEC dual channel failure results in the engine shutting down, with no manual reversion/control. (Well, it did unless recent updates have changed that). I was never clear why that decision could not be left to the pilot, because a frozen engine will/should not cause serious problems unless you make a significant change to the 'power demanded/required' vs the 'power available' (or, 'power being provided')
