NVG (ANVIS, AN/AVS) for HEMS, which is best USA vs. Europe vs. Israel?
I suspect that anyone who claims that NVG flying is not complicated is really only using them for Nav assist at night. If you are required to undertake missions at night to exactly the same standards as day (poor viz, low level, risk of inadvertent IMC, confined areas, hovering with limited references etc etc etc) then NVG will require at least a couple of hours of training every month.
