1.1 本规范规定了飞机在飞行、地面和水中操纵特性的适航性要求。 1.2 该材料是通过通用航空领域国际专家的公开共识开发的。这些信息是通过关注普通类飞机而创建的；然而，内容可能更广泛地适用，不应受到不适当的限制。本规范涵盖的主题包括:飞行特性、可控性、配平、稳定性、地面和水处理特性以及振动、冲击和高速特性。 1.3 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，适用的CAA发布的指导）。有关监督机构已接受本规范（全部或部分）作为符合其监管要求（以下简称“规则”）的可接受手段的信息，请参阅ASTM委员会F44网页（www。 astm.org/COMMITTEE/F44.htm）。 附件A1 将ASTM标准的符合方式映射到EASA CS-23，第5次修订或更高版本，以及FAA 14 CFR第23部分，第64次修订或更新版本的规则。 1.4 单位-- 本规范可能以国际单位制、英语工程单位制或两者兼有的形式提供信息；每个系统中所述的值不一定是精确等效的；因此，为了确保符合标准，每个系统应独立使用，并且不得将两个系统的值组合使用。 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，并确定监管限制的适用性。 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 addresses the airworthiness requirements for aeroplane handling characteristics in flight and on ground and water. 1.2 The material was developed through open consensus of international experts in general aviation. This information was created by focusing on Normal Category aeroplanes; however, the content may be more broadly applicable, and should not be unduly limited. The topics covered within this specification are: Flight Characteristics, Controllability, Trim, Stability, Ground and Water Handling Characteristics, and Vibration, Buffet, and High-speed Characteristics. 1.3 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 CAAs) concerning the acceptable use and application thereof. For information on which oversight authorities have accepted this specification (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements (hereinafter “the Rules”), refer to the ASTM Committee F44 web page (www.astm.org/COMMITTEE/F44.htm). Annex A1 maps the Means of Compliance of the ASTM standards to EASA CS-23, amendment 5, or later, and FAA 14 CFR Part 23, amendment 64, or later, rules. 1.4 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. 1.5 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 limitations 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.
