1.1 本指南旨在介绍无人驾驶飞机系统专业人员的基本主题知识、任务绩效、任务知识活动和功能，以获得无人驾驶飞机技术人员的称号。 1.2 技术人员资格包括: 1.2.1 特定系统或系统系列的类型评级可根据需要从本指南中获得适用于特定型号的适当技术内容； 1.2.2 在1级无人机上执行维护的最低知识、技能和能力； 1.2.3 在2级无人机上执行维护的最低知识、技能和能力；和 1.2.4 在3级无人机上执行维护的最低知识、技能和能力。 1.3 单位- 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.4 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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本指南旨在评估希望通过认证计划获得UAS技术员认证的合格人员的能力。 4.2 本指南旨在与认证提供商的管理、考试交付和考生准备的结构和材料配合使用。 4.3 本指南旨在与任何民航局（CAA）的指南或法规一起使用。 4.4 在本指南中，使用了基于整个UAS装备的分类系统。该分类系统的目的是根据整个系统的设备，培训技术人员维护UAS所需的知识。 UAS技术人员通常不仅负责维护无人驾驶飞机本身，还负责维护控制站、数据链路和外围设备（机外设备）。随着复杂程度的增加，UAS技术人员的知识范围也必须增加。该分类系统在 表1 . 4.5 完整的系统分类取决于系统各个组件的最高分类。 4.6 该分类模型被用作UAS典型系统的指南，而不是最终列表。 4.7 对于维护一个以上UAS模型的技术人员，建议进行等级认证( 表2- 4. ).

1.1 The purpose of this guide is to address the fundamental subject knowledge, task performance, and task knowledge activities and functions for unmanned aircraft system professionals to be titled unmanned aircraft system technician. 1.2 Technician qualifications include: 1.2.1 Type ratings on specific systems or families of systems can draw appropriate technical content from this guide, as needed, to be applicable to specific models; 1.2.2 The minimum knowledge, skills, and abilities to perform maintenance on Class 1 UAS; 1.2.3 The minimum knowledge, skills, and abilities to perform maintenance on Class 2 UAS; and 1.2.4 The minimum knowledge, skills, and abilities to perform maintenance on Class 3 UAS. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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. ====== Significance And Use ====== 4.1 This guide is intended to be used to assess competencies of qualified individuals who wish to become certified as a UAS Technician through a certification program. 4.2 This guide is intended to be used in concert with a certification provider’s structure and materials for management, exam delivery, and candidate preparation. 4.3 This guide is intended to be used in conjunction with any civil aviation authority’s (CAA’s) guidance or regulations. 4.4 In this guide, a classification system is used based on the equipage of the entire UAS. The purpose of this classification system is to train technicians on the knowledge necessary to maintain the UAS based on the equipage of the entire system. UAS Technicians are commonly responsible for maintaining not just the unmanned aircraft itself, but the control station, data links, and peripheral equipment (off-aircraft equipment) as well. As the level of complexity increases, so must the UAS Technician’s scope of knowledge. This classification system is presented in Table 1 . 4.5 Full system classification relies on the highest classification of the individual components of the system. 4.6 This classification model is used as a guide for typical systems of a UAS, not a definitive list. 4.7 For technicians who maintain more than a single model of UAS, a class qualification is recommended ( Tables 2- 4 ).
