Night Vision Goggles
I saw an advertisement by Bell offering a course in the use of NVG's. I'm not thinking doing it, but it got me wondering how they work.
I know the AAC use them - can any mil pilots explain how they work etc.
Bell say low level, middle-of-the-dark-night missions have become routine with NVG's, you 'can literally see in the dark', and night ops can be completed 'nearly as normally' as during the day.
True or advertising blurb?
What are the limitations?
