2、on or networking permitted without license from IHS-,-,-MIL-STD-3009iiFOREWORD1. 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
3、 preserve this widelyaccepted standard definition, and to comply with the Perry directive. 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 requirements.2. It is as
4、sumed 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 spec
5、ific classof NVIS and an aircraft is intended. The system specification requirements of anaircraft lighting system must be derived from other documents, after tailoring, suchas JSSG-2010-5.3. This document maintains exactly the same technical criteria for Class A and Class BNVIS compatibility as was
6、 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. This standard also adds exteriorlig
7、hting compatibility definitions and criteria.4. 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 theNavy.5. Beneficial
