Cockpit Night Vision Lighting. Night Vision Goggles (NVG) provide an remarkable capacity for the pilot/observer to "look" outside the aircraft at night. This vision allows a pilot to fly closer to terrain and perform safe landings & takeoffs as well as supply covert surveillance. The NVGs are sensitive to infra-red (IR) light which comes from the stars & moon. The IR light reflects off the terrain & is "seen" by the NVG's.
Cockpit lighting permits a pilot to see his instruments and radios at night. Cockpit lighting, on the other hand, emits mainly infra-red light itself for the reason that it's usually incandescent. Incandescent lighting emits more than 90% of its energy in the IR range that the NVG are sensitive to. Result, the NVGs are blinded by massive amounts of IR present in the cockpit since they're created to pick up nominal amounts of IR at a distance. So, common lighting isn't compatible with utilizing NVGs since they are sensitive to even the dimmest common cockpit lighting.
NVG aided flight operations originated throughout the Vietnam era and evolved for loads of years with elevated use by mostly military operators. The technical quality & capabilities of the NVGs improved little by little and began to get interest from other areas of aviation for its improved safety & operational capabilities.
In the late 1980's and early 1990's civilian operators began doing operations with NVG goggles & plenty of would turn off the aircraft lighting or tape over light sources that might not be turned off or dimmed. Today, NVG aided flight has turned out to be commonplace amongst military and civil (especially first responders) air operations. There are a variety of cockpit lighting solutions obtainable. See "Cockpit Lighting Tradeoffs" for more info. There are also rigorous regulatory standards that govern civil NVG air operations. These standards are regulated by the FAA, EASA, and other regulatory agencies global.
