1.1 本规范确立了轻型无人机系统（UAS）维护和持续适航的标准实践。 1.2 无人机系统至少被定义为由无人机和所有必需的子系统、控制站、所有必需的机组人员、指挥和控制（C2）链路以及任何必需的发射和回收设备组成的系统。 1.3 本规范的预期用途是为民航局（CAA）、自身或第三方确定无人机的持续适航性。本规范提供了轻型无人机持续适航性的核心要求，或使用基于风险的类别或两者的某些CAA操作批准。设想了其他要求，以解决本规范未解决的扩展操作和特性的要求。 1.4 本规范旨在支持根据规范开发的飞机 F2910 , F3002 , F3005 和 F3298 . 1.5 本规范旨在支持无人机操作。假设无人机的风险因作战概念、环境和其他变量而异。UAS上没有人这一事实可能会减少或消除一些危险和风险。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This specification establishes the standard practice for the maintenance and continued airworthiness of a lightweight unmanned aircraft system (UAS). 1.2 At a minimum, a UAS is defined as a system composed of the unmanned aircraft and all required subsystems, control station, all required crew members, command and control (C2) links, and any required launch and recovery equipment. 1.3 The intended use for this specification is for civil aviation authority (CAA), self-, or third-party determinations of continued airworthiness for UAS. This specification provides the core requirements for continued airworthiness of lightweight UAS or for certain CAA operational approvals using risk-based categories, or both. 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 aircraft developed in accordance with Specifications F2910 , F3002 , F3005 , and F3298 . 1.5 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. 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.
