EUROCAE ED-73C PDF

PURPOSE AND SCOPE

These minimum operational performance specifications are designed to ensure that aircraft Mode S Secondary Surveillance Radar (SSR) transponder equipments certificated to them will be compatible with ICAO Annex 10, Volume IV, Part I up to Amendment 82 and the 1^st edition of ICAO Document 9871 (Technical Provisions for Mode S Services and Extended Squitter).

These minimum operational performance specifications do not include detailed descriptions of Mode S coding formats, protocols and interfaces; these can be found in ICAO Annex 10, Volume IV.

This document replaces the previous version ED-73B.

Chapter 1 of this document provides information necessary to understand the need for the equipment requirements 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 general design specifications.

Chapter 3 contains the minimum performance specification for the equipment, defining performance under standard operating conditions.

Chapter 4 specifies 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 details recommended test procedures for demonstrating compliance with Chapters 3 and 4.

Chapter 6 specifies the performance demanded of the installed equipment. It also includes ground and flight tests of the installed equipment which may be required when performance cannot be adequately determined through testing under standard test conditions.
