1.1 本规范涵盖了与一般飞机性能相关的适航设计标准。该材料是通过通用航空领域国际专家的公开协商制定的。这些信息是通过关注普通类飞机而创建的。内容可能适用范围更广；申请人有责任证明更广泛的适用性作为一种特定的合规手段。本规范涵盖的主题包括:失速、起飞和着陆速度；起飞性能、距离和路径；攀登着陆性能和距离；Balked Landing。 1.2 打算将这些信息作为设计批准的合规手段的申请人必须就其可接受的用途和应用向其各自的监督机构寻求指导（例如，相关民航局（CAA）发布的指导）。 有关哪些监督机构已接受本标准（全部或部分）作为符合其监管要求的可接受手段（以下简称“规则”）的信息，请参阅ASTM委员会F44网页（www.ASTM.org/Committee/F44.htm）。 1.3 单位-- 本规范可能以国际单位制、英国工程单位制或两者兼有的形式提供信息。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且两个系统的值不得组合。 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 design standards associated with general aeroplane performance. The material was developed through open consensus of international experts in general aviation. This information was created by focusing on Normal Category aeroplanes. The content may be more broadly applicable; it is the responsibility of the Applicant to substantiate broader applicability as a specific means of compliance. The topics covered within this specification are: Stalling, Takeoff and Landing Speeds; Takeoff Performance, Distances and Path; Climb; Landing Performance and Distances; Balked Landing. 1.2 An applicant intending to propose this information as Means of Compliance for a design approval must seek guidance from their respective oversight authority (for example, published guidance from applicable civil aviation authorities (CAAs)) concerning the acceptable use and application thereof. For information on which oversight authorities have accepted this standard (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements (hereinafter “the Rules”), refer to ASTM Committee F44 webpage (www.astm.org/COMMITTEE/F44.htm). 1.3 Units— This specification may present information in either SI units, English Engineering units, or both. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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.
