SAS, are you Old and Bold?
The point is that modern helicopters are fairly reliable (I am glad to say) so there comes a point where you can destroy more helicopters and kill more people by training in higher risk manoeuvres (all flying carries risk, it can be higher or lower depending on the nature of the manoeuvres) than would ever be destroyed/killed by an actual case of the emergency.
Like when I first learnt to fly fixed wing (RAF University Air Squadron) we had to wear parachutes. When I asked if we would get any practical training in their use, the answer was no, because we would kill more people in the training than would be killed attempting a real bailout. And that was 1970s safety thinking.
Heli Simulators are still a fair way away from the real thing, but there is a lot of benefit in training the manoeuvres, maybe 90% as good as doing it in the real thing but with zero risk (a bit of vomit excepted!).
We had a double fatality in Bristow Aberdeen in the late 70s(?) during OEI training, so mandatory Sim would have saved them.
With the gradual spread of modern (relatively) low cost Sims, it is becoming much harder to justify not to use them for training. I would have thought CASA should take it in stages though - require training in the Sim for those excercises best done in a Sim, which as far as I am aware they either don't do, or only require it quite infrequently. Then the next step would be to ban aircraft training in high risk manoeuvres if there is a clear safety case for it.
To answer the original question, I am not aware of such a move in EASA land so far...
