1 METRICMIL-STD-30092 February 2001 SUPERSEDINGMIL-L-85762 ADEPARTMENT OF DEFENSEINTERFACE STANDARDLIGHTING, AIRCRAFT, NIGHT VISION IMAGING SYSTEM(NVIS) COMPATIBLEAMSC: N/A AREA: GDRQDISTRIBUTION STATEMENT A. Approved for public release; distribution is MIL-L-85762A was published in 1988 and served very well for eleven years as thestandard definition and interface criteria for NVIS compatibility. This new document(MIL-STD-3009) was derived from MIL-L-85762A as a way to preserve this widelyaccepted standard definition, and to comply with the Perry directive.

2 In compliancewith the Perry directive, this document no longer contains the lighting system designrequirements that were in MIL-L-85762; it now deals only with interface andperformance It is assumed that any contract for lighting equipment includes a TechnicalRequirements Document (TRD) (or similar document) that specifies the operationalfeatures of the lighting equipment. Such a TRD should reference this standard asthe NVIS compatibility requirement when full compatibility between a specific classof NVIS and an aircraft is intended.

3 The system specification requirements of anaircraft lighting system must be derived from other documents, after tailoring, suchas This document maintains exactly the same technical criteria for Class A and Class BNVIS compatibility as was required by MIL-L-85762. It also adds discussion ofClass C NVIS (colloquially known as leaky green ). Class C NVIS are generallycompatible with crewstation lighting that is class B compliant, so there are not yetany unique requirements for class C compatibility.

4 This standard also adds exteriorlighting compatibility definitions and Besides the original APPENDIX A and APPENDIX B, this document adds a thirdappendix (APPENDIX C), which provides rationale to explain the requirements inthis standard and was derived from a technical report originally published by Beneficial comments (recommendations, additions, and deletions) and any pertinentdata which may be of use in improving this document should be addressed toASC/ENFC, 2530 Loop Road West, Wright-Patterson AFB OH , aircraft , NIGHT VISION IMAGING SYSTEM (NVIS) COMPATIBLE.
