1.1 本规范涵盖了飞机适航和设计的系统和设备方面。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1级、2级、3级和4级普通类别飞机创建的。内容可以更广泛地适用；申请人有责任证明作为一种特定的合规手段的更广泛的适用性。本规范涵盖的主题有:基本信息、电气系统、环境要求、手动飞行控制、自动飞行控制、飞行数据和语音记录、危险缓解、液压系统、仪表、机械系统和设备、外部照明、氧气系统、气动系统、防雷和高-强度辐射场（HIRF）防护。 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向其各自的监督机构寻求指导（例如，适用的民用航空机构（CAAs）发布的关于其可接受用途和应用的指导）。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（以下简称“规则”）的可接受手段的信息，请参考ASTM委员会F44网页（www.astm.org/Committee/F44.htm）。 1.3 本文件可以用SI单位、英语工程单位或两者提供信息；每个系统中所述的值可能不完全等同。每个系统应独立使用；合并两个系统的值可能导致不符合标准。 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 the systems and equipment aspects of airworthiness and design for aircraft. The material was developed through open consensus of international experts in general aviation. This information was created by focusing on Level 1, 2, 3, and 4 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: Basic Information, Electrical Systems, Environmental Requirements, Manual Flight Controls, Automatic Flight Controls, Flight Data and Voice Recording, Hazard Mitigation, Hydraulic Systems, Instrumentation, Mechanical Systems and Equipment, Exterior Lighting, Oxygen Systems, Pneumatic Systems, Lightning Protection, and High-Intensity Radiated Field (HIRF) Protection. 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 the ASTM Committee F44 web page (www.astm.org/COMMITTEE/F44.htm). 1.3 This document may present information in either SI units, English Engineering units, or both; the values stated in each system may not be exact equivalents. Each system shall be used independently of the other; combining values from the two systems may result in nonconformance with the standard. 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.
