slightly predictable pprune type of condescending answer ...Thanks !!
This is for co pilot use which can only add to safety. By the way i know of a lot of military pilots who did hundreds of hours nvg,s without very expensive compatable cockpits ,by putting tape and plastic screens over the lights. I imagine there will be civil pilots using nvg,s for private flying but maybe they want to keep quiet about it !! ( if so you can always pm me)
