第5部分讨论了电气实践和安装的一般特征，并讨论了对机场安装具有特殊意义的特征。假设本手册的读者熟悉电路和设计概念，但可能不熟悉机场设施的某些特征，这些特征在其他设施中不太常见。

Part 5 discusses the general features of electrical practices and installations and also addresses those features which are of special significance for aerodrome installations. It is assumed the readers of the manual will be familiar with electrical circuits and desin concepts, but may not be familiar with certain features of aerodrome installations which are less frequently encountered in other installations.
