PURPOSE AND SCOPE

This minimum operational performance specification is for aircraft Air Data Modules (ADM) that measure static or total pressure.

It is designed to ensure that compliant equipment for static pressure measurement will meet the performance standard required to support Reduced Vertical Separation Minima (RVSM) operation throughout the operational life of the system.

Chapter 1 of this document 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 general design requirements.

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

Chapter 4 describes the environmental test conditions, which provide a laboratory means of determining the overall performance characteristics of the equipment that may be encountered in actual operations.

Chapter 5 describes recommended test procedures for demonstrating compliance with Chapters 3 and 4.

Chapter 6 specifies the minimum acceptable level of performance, and test procedures for verifying equipment performance when installed in an aircraft.
