本文件旨在提出设计建议，为运输机中令人满意且安全的电气安装提供依据。本文件并非完整的电气安装设计手册。然而，安全要求在整个电气系统中延伸得如此彻底，以至于文件中几乎没有涉及安装的区域。人们认识到，个别情况可能会改变任何设计的细节。因此，本文件不应视为强制性文件，而应作为良好电气应用和安装设计的指南。多年来，运输机电气系统的重要性迅速增加，直到现在它们被用于飞机成功运行所需的许多功能。越来越多的这些功能对飞机及其乘客的安全至关重要。电力系统可用功率的大幅增加是飞机安全的另一个因素。 这些考虑因素使得从安全性和可靠性的角度仔细考虑飞机电气设计实践至关重要。相信这份文件将有助于指出潜在的困难和解决许多问题。

It is the purpose of this document to present design recommendations that will provide a basis for satisfactory and safe electrical installations in transport aircraft. This document is not intended to be a complete electrical installation design handbook. However, the requirements for safety extend so thoroughly throughout the electric systems that few areas of the installation are untouched by the document. It is recognized that individual circumstances may alter the details of any design. It is, therefore, important that this document not be considered mandatory but be used as a guide to good electrical application and installation design. Transport aircraft electric systems have rapidly increased in importance over a number of years until they are now used for many functions necessary to the successful operation of the aircraft. An ever increasing number of these functions are critical to the safety of the aircraft and its occupants. The greatly increased power available in electric systems is another factor in aircraft safety. These considerations make it essential that aircraft electrical design practices be carefully considered from the standpoint of safety and reliability. It is believed that this document will be of value in pointing out potential difficulties and in solving many of the problems.
