There are multiple NVG cockpit lighting configurations available from ASU based upon aircraft type and operational use. ASU uses a multitude of NVG filter types to ensure that cockpits conform to all required instrument lighting, clarity, color discrimination and daylight readability requirements. A standard NVG cockpit modification may include a combination of glass filters, bezels, postlighting and floodlighting to modify all instrumentation.


Most standard aircraft cockpit instrument lighting is not configured for use with Night Vision Goggles. Standard red, white and/or yellow cockpit instrument lighting greatly reduces the benefit provided by the use of NVGs because of increased glare, reflection and reduction in gain. To provide the maximum benefit of NVG use, ASU modified cockpits incorporate specially designed and manufactured ANVIS glass and polymeric/acrylic filters for LCD, CRT, Plasma, Liquid Crystal and Gas Discharge LED instrument and avionics displays for optimized daylight readability.
