MIL-L-85762A

Abstract

This specification establishes performance, general configuration, test and acceptance requirements for NVIS (see <a>6.5.1</a>) compatible aircraft interior lighting. It is applicable to all systems, subsystems, component equipment and hardware which provide the lighting environment in aircraft crewstations and compartments where NVIS are employed. <br>The purpose of this specification is to provide performance requirements and testing methodology to ensure effective and standardized aircraft interior lighting for NVIS compatibility. <br>Night Vision Imaging System (NVIS) compatible aircraft interior lighting shall be of the following types and classes, as specified (see <a>6.2</a>.b). </span><pre> Type I Lighting compatible with any Direct View Image NVIS (see <a>6.5.1.1</a>) utilizing generation III Image intensifier tubes. Type II Lighting compatible with any Projected Image NVIS (see <a>6.5.1.2</a>) utilizing generation III Image intensifier tubes. Class A Lighting compatible with NVIS utilizing 625 nm minus blue objective lens filters (see <a>6.5.1.3</a>) with the specifications of <a>Figure 1</a>. Class B Lighting compatible with NVIS utilizing 665 nm minus blue objective lens filters (see <a>6.5.1.4</a>) with the specifications of <a>Figure 2</a>.</pre> <br> <strong>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Systems Engineering and Standardization Department (Code 93), Naval Air Engineering Center Lakehurst, NJ 08733, by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.</strong> <br><b><u>Intended Use:</u></b> The lighting requirements specified herein are intended to cover all of the aircraft interior lighting of equipment areas, crewstations and compartments in which aircrew members must perform their duties while wearing NVIS. <br>
