If all those hours have been flown - not sure how you know who did what and in what conditions
You know I'm not spouting hard numbers, but R44s and many other light single, VFR-only helicopters fly at night all the time in the US, and historically this has gone on probably since the beginning of the helicopter. it's just common sense. By way of a single example, once upon a time, that's all police departments flew, before they started squeezing taxpayers for bigger and better.
- then they were probably over well-lit enough areas to give adequate orientation, as the rule requires.
Of course that is the case.
But, if they did that without being able to see the ground, then they did not fly in accordance with the rules for night VFR - simples.
That is not the case.
Do tell how you control your pitch and roll attitude in an unstabilised aircraft without an external reference if you don't have an AI and you can't see the actual horizon. Perhaps the ubiquitous i-pad?
You don't.
Either you and I are not on the same page (as usual), or you are serving up non-sequiturs for some reason.
Bottom line: there are lots of night VFR helicopter op's in the US in un-stabilized, VFR-only light singles,
all done 100% legally without reference to instrument flight tools and techniques, without them falling from the sky in droves. It's simply not a big problem in this country, nor is it some sort of anathema, either.
