Product Code:SAE ARP4169
Title:Night Vision Goggle (Nvg) Filters
Issuing Committee:A-20ac Crew Station And Interior Lighting Committee
Scope: This SAE Aerospace Recommended Practice (ARP) discusses the desired characteristics of night vision goggle (NVG) filters that can be used with incandescent, electroluminescent (EL) and light emitting diode (LED) light sources to achieve NVG compatible lighting of aerospace crew stations. This document also discusses the parameters that need to be considered when selecting a night vision goggle/daylight viewing (NVG/DV) filter for proper contrast enhancement to achieve readability in daylight.The recommendations set forth in this document are to aid in the design of NVG compatible lighting that will meet the requirements of MIL-L-85762A.

Product Code:SAE ARP4043
Title:Flight Line Grounding and Bonding of Aircraft
Issuing Committee:Ae-4 Electromagnetic Environmental Effects (E3) Committee
Scope: Grounding is the process of connecting one or more metallic objects and ground conductors to ground electrodes. Bonding is the process of connecting two or more metallic objects together by means of a conductor. Bonding is done to equalize electrostatic potential between two or more conductive objects. The generation of static electricity cannot be prevented entirely. Its generation is not in itself a hazard provided it can be dissipated safely. The hazard is encountered when changes accumulate to the extent that a spark discharge occurs to some other object in the presence of hazardous atmospheres, dusts, etc. Elimination of such potential hazards, therefore, requires proper grounding or neutralization of the charges to avoid dangerous accumulations.
