1.1 本规范涵盖了动力固定翼轻型运动飞机（“飞机”）设计的适航要求 1.2 本规范适用于法规规定的轻型运动飞机/飞机的设计，仅限于VFR飞行。 1.3 单位-- 本标准中给出的数值以国际单位制为单位，应视为标准。括号中给出的值是对英寸-磅（或其他）单位的数学转换，仅供参考，不被视为标准。每个系统中规定的值可能并不完全相等。在可能不清楚的地方，一些方程直接在方程后面提供结果的单位。 1.4 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。 1.5 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 airworthiness requirements for the design of powered fixed wing light sport aircraft, an “airplane.” 1.2 This specification is applicable to the design of a light sport aircraft/airplane as defined by regulations and limited to VFR flight. 1.3 Units— The values given in this standard are in SI units and are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound (or other) units that are provided for information only and are not considered standard. The values stated in each system may not be exact equivalents. Where it may not be clear, some equations provide the units of the result directly following the equation. 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 requirements 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.
