PURPOSE AND SCOPE

This Minimum Operational Performance Specification (MOPS) is designed to ensure that Light Aviation Secondary Surveillance Radar (SSR) Transponder equipments (LAST) in compliance with the MOPS, will be compatible with ICAO Annex 10, Volume IV, as to Amendment 77.

NOTE 1: This MOPS also includes requirements and tests for a dedicated LAST power source (e.g. battery), a dedicated alticoder and antenna subsystem which may also be part of the LAST.

NOTE 2: A National Civil Aviation Authority may approve the use of a low RF power LAST for operation in its own country ensuring that reliable performance of collision avoidance and ground systems can be demonstrated. This LAST would not be ICAO compliant. With the exception of the lower transmitter power and adapted receiver sensitivity (see paragraph 1.4.2.4 and paragraph 3.2), it shall otherwise be in general accordance with this MOPS. In order to prevent the use of the equipment for flights in the airspace of other states, it should be clearly labelled as nationally approved only.

This Minimum Operational Performance Specification does not include detailed descriptions of Mode S coding formats, protocols and interfaces; these can be found in ICAO Annex 10, Volume IV.

Chapter 1 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 to provide a laboratory means of determining the overall performance characteristics of the equipment under conditions representative of those that 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 requirements of the installed equipment. It also includes ground and flight tests of the installed equipment that may be required when performance cannot be adequately determined through testing under standard test conditions.
