Scope
This SAE Aerospace Recommended Practice (ARP) reviews the basics of NVIS compatibility and discusses the specific illuminated pushbutton switch and indicator requirements for sunlight readability, color, luminance, and NVIS radiance when used in NVIS compatible cockpits.
The recommendations and special considerations set forth in this document are made to give the design engineer a better understanding of MIL-L-85762A NVIS compatibility requirements and to provide information on the visual characteristics of NVIS compatible pushbutton switch and indicator displays.
Rationale
Warning, caution and advisory push-button switches and indicators are considered by pilots to be one of the most important items in the aircraft crew station. Due to the different colors, these push-button switches and indicators are particularly difficult in an NVG green-lighted compatible crew station. This specific technology, which is utilized to deal with the design of these devices is covered in this document.

Issuing Committee
The purpose of the A-20 Aircraft Lighting Committee is to provide a forum for the development of aerospace standards in aircraft lighting that will fulfill the needs and requirements of operation control and utility. The scope includes both interior and exterior lighting. A list of the technical reports developed by the A-20 Committee can be obtained by searching on 'aircraft lighting' and selecting 'standards', from the SAE Home Page. A-20 Standards

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
