本文件中的航空航天推荐规程适用于运输类涡轮动力飞机上使用的氮基可燃性降低装置（FRM）。因此，本文推荐的做法仅适用于运输类飞机，并特别关注当代惰化系统设备。此类系统在本文件中称为油箱惰化系统（FTIS）。本文件不包括以下内容:军用飞机应用；除中空纤维膜（HFM）和变压吸附（PSA）以外的空气分离技术；常规未加热机翼油箱或飞机干舱的惰化；预期未来惰性气体产生的技术解决方案。本文件中的建议旨在为飞机制造商提供有关当代飞机油箱惰化系统关键问题的指导，以补充FAA咨询通告AC 25中的指导。 981-2. 本文件还为系统和部件设计师和制造商提供建议，说明在设计运输飞机油箱易燃性降低装置的安全、低风险解决方案时，必须评估和解决哪些方面。因此，本文中的信息旨在作为一些系统设计方面的指南，但主要确定在设计燃油箱可燃性降低惰化系统时必须解决的问题。

The Aerospace Recommended Practices of this document are intended for nitrogen-based Flammability Reduction Means (FRM) implemented on transport category, turbine powered airplanes. The recommended practices herein, therefore, relate only to the transport category aircraft, and focus specifically on contemporary inerting systems equipment. Such systems are referred to a Fuel Tank Inerting Systems (FTIS) in this document. This document does not cover the following: Military aircraft applications; Air separation technologies other than hollow fiber membrane (HFM) and pressure swing adsorption (PSA); Inerting of conventional unheated wing tanks or aircraft dry bays; Expected future technology solutions for the generation of inert gas.The advice contained in this document is aimed towards providing aircraft manufacturers with guidance on the key issues associated with contemporary aircraft fuel tank inerting systems to supplement the guidance in FAA Advisory Circular AC 25.981-2. This document also provides system and component designers and manufacturers with advice on what aspects must be evaluated and addressed when designing a safe, low risk solution for transport aircraft fuel tank Flammability Reduction Means. As such, the information herein is intended as a guide for some system design aspects, but primarily identifies the issues which must be addressed in designing an inerting system for fuel tank flammability reduction.
