I may have mentioned this before, but about 20 years ago, a colleague and I (both Brit mil) took part in a simulator assessment at RAE Bedford which was one of the first studies into helicopter flight in DVE (degraded visual environment).
We flew the same profile each time but with the simulator staff adjusting the control responses (everything from a full ASE/SAS to a completely unstabilised aircraft which was modeled on R22) and then changing the quality of the visual cues.
For two experienced mil pilots (both QHIs) it was a chastening experience to see how quickly our performance degraded as both the stability of the helo and the visual cues went downwards.
The worst was, of course, the R22 in the worst visual cues (still not fully IMC but pretty close) - absolutely 100% concentration just to keep it the right way up but with no capacity for navigation, communication or any other tasks.
Sadly there will still be pilots out there who think they are better, more skillful or just luckier - and they are the same pilots we will be reading about on this forum in the years to come.
Don't do it!
