Scope.
This standard establishes requirements for the emission characteristics of aircraft lighting and display equipment that is intended for use with night vision imaging systems (NVIS). It is applicable to all systems, subsystems, component equipment, and hardware that provide the lighting environment on aircraft where NVIS are employed.
This document is applicable to NVIS specific performance requirements but it does not contain general lighting requirements. The contracting activity should extract and tailor applicable general lighting requirements from JSSG-2010-5 and include those requirements in the contract.
Purpose.
The purpose of this document is to provide interface requirements and testing methodology to ensure compatible and standardized aircraft interior lighting for NVIS compatibility.
Classification.
Night vision imaging system (NVIS) compatible aircraft interior lighting is divided into the following types and classes.
Type I Lighting compatible with any direct view image NVIS (see 3.1.1) utilizing Generation Ill image intensifier tubes.
Type ll Lighting compatible with any projected image NVIS (see 3.1.2) utilizing Generation Ill image intensifier tubes.
Class A Lighting compatible with NVIS utilizing 625 nm minus blue objective lens filters (see 3.1.3) with the specifications in FIGURE 1.
Class B Lighting compatible with NVIS utilizing 665 nm minus blue objective lens filters (see 3.1.4) with the specifications in FIGURE 1.
Class C Lighting compatible with NVIS having a “green leak” as shown in FIGURE 1. This edition of this document assumes that lighting meeting class B compatibility criteria is also compatible with Class C NVIS.
LISUN following instruments fully meet MIL-STD-3009 LIGHTING, AIRCRAFT, NIGHT VISION IMAGING SYSTEM (NVIS) COMPATIBLE
