本文件包含主动机载结冰探测系统（FIDS）的最低运行性能规范（MOPS）。本MOPS规定了氢火焰离子化检测器的运行性能，该性能是满足最低标准的设备设计和制造监管要求以及安装在飞机上时可接受的合规性指南所必需的最低性能。本文件不考虑在地面操作期间检测飞机上的积冰。 本MOPS是为在1.3和2.3中定义的飞机上使用FID而编写的。FID及其功能的预期最低性能规范见第3节。第3节中定义的最低性能要求不考虑安装在飞机上的系统性能。为了满足监管或操作要求，安装在飞机上的系统可能需要超过最低性能的性能。本主题被视为第6节。 本MOPS文件的结构如下:功能或组件的操作性能规范指的是超过规定最低要求的设备能力，被确定为可选特性。本文件中使用的“设备”一词包括系统正确执行其预期功能所需的所有组件和单元。例如，设备可以包括1.4中列出的所有组件。不应推断每个FIDS设计必然包括该节中列出的所有组件或装置。 这将取决于FIDS制造商选择的具体设计。

This document contains minimum operational performance specification (MOPS) of active on-board INFLIGHT ICING DETECTION SYSTEMS (FIDS).This MOPS specifies FIDS operational performance which is the minimum necessary to satisfy regulatory requirements for the design and manufacture of the equipment to a minimum standard and guidance towards acceptable means of compliance when installed on an AIRCRAFT.Detection of ICE accreted on the AIRCRAFT during ground operations is not considered in this document. This MOPS was written for the use of FIDS on AIRCRAFT as defined in1.3and2.3.Expected minimum performance specifications for FIDS and their functions are provided inSection 3.The minimum performance requirements as defined inSection 3do not consider SYSTEM performance as installed on the AIRCRAFT. Performance in excess of the minimum performance may be required by the SYSTEM installed on an AIRCRAFT in order to meet regulatory or operational requirements. This topic is considered inSection 6.This MOPS document is structured as follows:Operational performance specifications for functions or COMPONENTS that refer to equipment capabilities that exceed the stated minimum requirements are identified as optional features.The word ¿¿¿equipment¿¿¿ as used in this document includes all COMPONENTS and units necessary for the SYSTEM to properly perform its intended function(s). For example, the ¿¿¿equipment¿¿¿ may include all of the COMPONENTS listed in1.4. It should not be inferred that each FIDS design will necessarily include all of the COMPONENTS or units listed in that Section. This will depend on the specific design chosen by the FIDS manufacturer.
