1.1 本规范涵盖轻型无人驾驶飞机系统设计的适航性要求。本规范定义了无人驾驶飞机系统（UAS）的基线验证要求。 1.2 至少，无人机是指由无人驾驶飞机和所有所需的机载子系统、有效载荷、控制站、其他所需的机外子系统、任何所需的发射和回收设备、所有所需机组人员以及UA和控制站之间的指挥和控制（C2）链路组成的系统。 1.3 其目的是制定CAA的本实践标准，即无人机适航性的自行或第三方确定。本规范提供了使用基于风险类别的某些CAA运营批准的轻型（UAS）适航认证的核心要求。设想了额外的要求，以解决本规范未涉及的扩展操作和特性的要求。 1.4 本规范旨在支持无人机操作。据推测，无人机的风险将根据作战概念、环境和其他变量而变化。 无人机上没有人这一事实可能会减少或消除一些危险和风险。然而，根据民航局的决定，本规范可适用于其他无人机操作。 1.5 单位-- 以英制单位表示的数值应视为标准。SI中的值仅供参考。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers the airworthiness requirements for the design of light unmanned aircraft systems. This specification defines the baseline verification requirements for an unmanned aircraft system (UAS). 1.2 As a minimum, a UAS is defined as a system composed of the unmanned aircraft and all required on-board subsystems, payload, control station, other required off-board subsystems, any required launch and recovery equipment, all required crew members, and command and control (C2) links between UA and the control station. 1.3 The intent is for this standard of practice for CAA, self- or third-party determinations of airworthiness for UAS. This specification provides the core requirements for airworthiness certification of lightweight (UAS) for certain CAA operational approvals using risk-based categories. Additional requirements are envisioned to address the requirements for expanded operations and characteristics not addressed by this specification. 1.4 This specification is intended to support UAS operations. It is assumed that the risk of UAS will vary based on concept of operations, environment, and other variables. The fact that there are no human beings onboard the UAS may reduce or eliminate some hazards and risks. However, at the discretion of the CAA, this specification may be applied to other UAS operations. 1.5 Units— The values in Imperial units are to be regarded as the standard. The values in SI are for information only. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
