民用飞机机载设备的环境鉴定试验研究

民用飞机机载设备的环境鉴定试验是表明设备符合适用的环境标准，进而满足其适用的技术标准规定（TSO）的重要工作内容，对机载设备的适航审定具有重要意义。目前，国内民用飞机机载设备的环境鉴定试验工作还在持续完善阶段。本文以某机载设备的环境鉴定试验为例，介绍了一套机载设备环境鉴定试验的工作流程，包括环境鉴定试验计划制定、环境试验规程开发、环境试验执行3个阶段，并结合设备适用的最低操作性能标准（MOPS）和DO-160标准（机载设备环境条件和试验程序），详细描述了各阶段的工作内容和重点，以及适航联络的规划和工作建议。该设备已成功取得TSO证，表明该流程能够有效应用于机载设备的环境鉴定试验工作开展并支持设备适航审定，可为后续机载设备的环境鉴定试验工作提供参考。

Research on Civil Airborne Equipment Environmental Qualification Test

The Environmental Qualification Test of civil aircraft airborne equipment is to demonstrate that the equipment meets the applicable environmental standards, and further meets the Technical Standards Order applicable to it, which is of great significance to the airworthiness certification of airborne equipment. At present, the Environmental Qualification Test of civil aircraft airborne equipment in domestic is still in the continuous improvement stage. This paper takes the environmental qualification test of certain airborne equipment as an example, introduces a set of workflow for the Environmental Qualification Test, including three stages: Environmental Qualification Test plan development, environmental test procedure development, and qualification testing. Then combined with the Minimum Operational Performance Standard (MOPS) applicable to the equipment and the DO-160 standard (Environmental Conditions and Test Procedures for Airborne Equipment), it describes in detail about the work content and focus of each stage in the workflow, as well as the planning of airworthiness liaison and suggestions. This equipment has got the TSO approval, indicating that this workflow can be effectively applied to the Environmental Qualification Test of airborne equipment and support for the airworthiness certification, and can also provide reference for the Environmental Qualification Test of subsequent airborne equipment.
