1.1 本规范涵盖了动力或非动力固定翼轻型运动飞机“滑翔机”设计的适航性要求 1.2 本规范适用于法规规定的轻型运动飞机滑翔机的设计，仅限于白天的VFR飞行。 1.3 在本规范中，滑翔机被定义为一种重于空气的飞机，通过固定机翼的空气动态反应保持在空中，并且在自由飞行中保持高空的能力不取决于动力装置的推进。动力滑翔机在本规范中定义为配备动力装置的滑翔机，其飞行特性与动力装置未运行时的滑翔器相同。 1.4 以国际单位表示的数值视为标准值。括号中给出的值仅供参考。 1.5 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，并确定监管要求的适用性。 1.6 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 covers airworthiness requirements for the design of a powered or non-powered fixed wing light sport aircraft, a “glider.” 1.2 This specification is applicable to the design of a light sport aircraft glider as defined by regulations and limited to day VFR flight. 1.3 A glider for the purposes of this specification is defined as a heavier than air aircraft that remains airborne through the dynamic reaction of the air with a fixed wing and in which the ability to remain aloft in free flight does not depend on the propulsion from a power plant. A powered glider is defined for the purposes of this specification as a glider equipped with a power plant in which the flight characteristics are those of a glider when the power plant is not in operation. 1.4 The values stated in SI units are to be regarded as standard. The values given in parenthesis are for information only. 1.5 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 requirements prior to use. 1.6 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.
