1.1 本规范阐述了飞机电力推进系统设计和安装的适航性要求。除非另有明确说明，否则混合动力电力推进系统是含蓄的。本规范的编写重点是具有常规系统布局、推进特性和操作的电力推进系统。内容可能更广泛适用；申请人有责任证明更广泛的适用性，作为一种具体的合规手段。 1.2 打算将此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使用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）。 有关监督机构接受本标准（全部或部分）作为符合其监管要求（以下简称“规则”）的可接受合规手段的信息，请参阅ASTM委员会F44网页（www.ASTM.org/Committee/F44.htm）。 附录A1 将本规范中描述的合规方法映射到EASA CS-23修订版5或更高版本以及FAA 14 成本加运费 第23部分，修正案64或更高版本。 1.3 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。 1.4 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 addresses airworthiness requirements for the design and installation of electric propulsion systems for aeroplanes. Hybrid-electric propulsion systems are addressed implicitly unless explicitly stated otherwise. This specification was written with the focus on electric propulsion systems with conventional system layout, propulsion characteristics, and operation. The content may be more broadly applicable; it is the responsibility of the applicant to substantiate broader applicability as a specific means of compliance. 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 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 the ASTM Committee F44 web page (www.astm.org/COMMITTEE/F44.htm). Annex A1 maps the Means of Compliance described in this specification to EASA CS-23, amendment 5, or later, and FAA 14 CFR Part 23, amendment 64, or later. 1.3 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. 1.4 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.
