本文件规定了栓系无人飞机系统（UAS）的一般要求和制造要求，包括由地面设备提供动力的重于空气的栓系无人飞行器（UA）。本规范适用于无人机，其中系绳的目的是为无人机供电并提供机械约束。未从系绳接收电力且仅受系绳约束的无人飞机（UA）被称为ISO21384-2; 然而，本文件中有一些条款适用于系绳设备（e。 g、 绞车和电缆）。 本文件适用于UAS的开发、制造、工业应用和交付。

This document specifies general and manufacturing requirements for tethered unmanned aircraft systems (tUAS), including heavier-than-air tethered unmanned aircraft (tUA), which are powered by equipment on the ground. The specifications are intended for tUAS where the purpose for the tether is to supply power to the tUA as well as to provide a mechanical restraint. Unmanned aircrafts (UAs) that are not receiving power from and only restrained by the tether are referred to ISO？21384-2; however, there are clauses in this document that apply to the tethering equipment (e.g. winches and cables). This document is applicable to the development, manufacturing, industrial applications and delivery of tUAS.
