本文件提供了将飞机设备电磁、电气和机械鉴定标准（即DO-160、MIL-STD-461、MIL-STD-704和MIL-STD-810）应用于军用民用飞机认证和安装在民用飞机上的军用飞机设备的指南。该指南确定了设备环境鉴定标准符合民用或军用飞机认证要求的地方。相反，本指南将确定设备环境鉴定标准存在差异的地方，这些差异不符合民用或军用飞机认证要求的意图，以及这些差异基于设备关键性、安装位置和/或其他变量的重要性。

This document provides guidance for applying aircraft equipment electromagnetic, electrical, and mechanical qualification standards (i.e., DO-160, MIL-STD-461, MIL-STD-704, and MIL-STD-810) to civil aircraft certification intended for military use and for military aircraft equipment installed on civil aircraft. The guidance identifies where the equipment environmental qualification standards meet the intent of both the civil or military aircraft certification requirements. Conversely, the guidance will identify where the equipment environmental qualification standards have differences that do not meet the intent of the civil or military aircraft certification requirements and when these differences matter based on equipment criticality, installation location, and/or other variables.
