1.1 本规范涵盖了具有内燃机发电的飞机的适航性和设计的电气系统、电气设备和电力分配方面。该材料是通过通用航空国际专家的公开共识开发的。该信息是通过关注普通类别的飞机而创建的。内容可以更广泛地适用；申请人有责任证明作为特定合规手段的更广泛适用性。 1.2 打算将该信息作为设计批准的合规手段的申请人应向其各自的监督机构寻求关于其可接受使用和应用的指导（例如，适用的民用航空当局（CAAs）发布的指导）。有关哪些监管机构已接受本规范（全部或部分）作为遵守其监管要求（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 将本规范中描述的符合性手段映射到EASA CS-23，修正案5或更高版本，以及FAA 14 CFR Part 23，修正案64或更高版本。 1.3 单位- 本标准可以用SI单位、英语工程单位或两者来呈现信息；每个系统中陈述的值不一定完全等同；因此，为确保符合标准，每个系统应独立使用，两个系统的数值不得合并使用。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（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》中确立的国际公认的标准化原则制定的。

1.1 This specification covers electrical systems, electrical equipment, and electrical power distribution aspects of airworthiness and design for aeroplanes with combustion engine generation of electrical power. 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. 1.2 An applicant intending to propose this information as Means of Compliance for a design approval shall 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 specification (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements (hereinafter “the Rules”), refer to 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 Units— This standard 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.
