This ARP covers three common light sources, incandescent, electroluminescent and light emitting diode that, when NVG filtered, can be used to illuminate NVG compatible aerospace crew stations. It is recognized that many other different light sources can also be used for this purpose. Also see 2.1.1 for other SAE documents that cover particular applications within the crew station environment.
This ARP sets forth recommendations for the design of NVG compatible lighting, utilizing these light sources, that will meet the requirements of MIL-L-85762 Lighting, Aircraft, Interior, Night Vision Imaging System (NVIS) Compatible. This also includes the replacement document MIL-STD-3009: Lighting, Aircraft, Night Vision Imaging System (NVIS) Compatible.
Although this ARP concentrates on lamp light sources for illumination, the information contained within this ARP may be directly applied to incandescent, electroluminescent and light emitting diode information display devices. Regardless of the light source, the focus of this document is the understanding that the radiometric energy that can be amplified by the Night Vision Goggles (NVG’s) must be filtered to such an extent that it will not impact the operational use of the NVG’s while still allowing sufficient visible (photometric) energy to be viewed by the pilot.
This document shows recommended industry practices, requirements and design recommendations for Night Vision Goggle (NVG) compatible light sources within the crew station. The most recent revision to this document was to update the reference documents, add more technical details and expand design recommendations for LEDs. The recommendations contained within this document apply to both military and civilian aircraft.
