EUROCAE ED-103B PDF

PURPOSE AND SCOPE

This document contains the 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 in Section 1.3 SYSTEM DESCRIPTION and Section 2.3 INTENDED FUNCTIONS.

Expected minimum performance specification for FIDS and their FUNCTIONS are provided in CHAPTER 3.

The minimum performance requirements as defined in CHAPTER 3 do 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 in CHAPTER 6.

This MOPS document is structured as follows:

CHAPTER 1

Provides information required to understand the need for the equipment characteristics and tests defined in the remaining chapters. It describes typical equipment applications and operational objectives and is the basis for the performance criteria stated in CHAPTER 2 to CHAPTER 4. Definitions essential to proper understanding of this document are also provided in CHAPTER 1.

CHAPTER 2

Contains FIDS intended functions, general design requirements and general reporting and tests requirements.

CHAPTER 3

Contains the Minimum Operational Performance Specification for the equipment, defining performance requirements under ENVIRONMENTAL INFLIGHT ICING CONDITIONS likely to be encountered in flight.

CHAPTER 4

Describes the environmental test conditions which provide a laboratory means of determining the overall performance characteristics of the equipment under conditions representative of those which may be encountered in actual operations.

CHAPTER 5

Describes recommended test procedures for demonstrating compliance with CHAPTER 3 requirements.

CHAPTER 6

Provides guidance on the installed SYSTEM. Installation effects may require FIDS performance in excess of the minimum requirements provided in this MOPS.

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 in Section 1.4 EQUIPMENT COMPONENTS. 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.
