Aircraft Night Vision Lighting. Night Vision Goggles (NVG) provide an astonishing ability for the pilot/observer to "look" outside the aircraft at night. This vision makes it possible for a pilot to fly closer to terrain & perform safe landings & takeoffs along with provide 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 "noticed" by the NVG's.
Cockpit lighting permits a pilot to see his instruments and radios at night. Cockpit lighting, although, emits mainly infra-red light itself since it's generally 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 quantities of IR present in the cockpit since they are created to pick up nominal amounts of IR at a distance. So, common lighting is not compatible with working with NVGs since they are sensitive to even the dimmest standard cockpit lighting.
NVG aided flight operations originated during the Vietnam era & evolved for a lot of years with increased use by specifically military operators. The technical quality & capabilities of the NVGs improved little by little and began to receive interest from other places of aviation for its improved safety & operational capabilities.
In the late 1980's & early 1990's civilian operators began doing operations with NVG goggles and several 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 among military & civil (particularly first responders) air operations. There are many different cockpit lighting solutions available. See "Cockpit Lighting Tradeoffs" for more facts. There are also rigorous regulatory standards that govern civil NVG air operations. These standards are regulated by the FAA, EASA, & other regulatory agencies global.
NVG Cockpit lighting for aircraft. Aero Dynamix is the fully approved NVIS modification center for many aircraft manufactures. Aero Dynamix meets or exceeds all day time readability & NVIS compatibility needs. Our design method utilizes a combination of internal modifications & overlays which minimizes the use of external filtering and optimizes daylight readability.
