However, I guess my point is .... a visual black hole approach is difficult for anyone. I don't see how being IFR rated makes it any easier or less disorienting.
It's not like there's an ILS at these places !
P.S. A NVFR pilot who regularly exercises that rating would arguably be safer at a black hole aerodrome than an IFR rated pilot, who infrequently flys at night.
There are so many variables here. It just makes me mad to read the rash generalisations from the armchair experts.
