Introduction

This document contains Minimum Operational Performance Standards (MOPS) for airborne equipment for Automatic Dependent Surveillance-Broadcast (ADS-B) and Traffic Information Service - Broadcast (TIS-B) utilizing 1090 MHz Mode-S Extended Squitter (1090ES). The supporting hardware can be incorporated within other on-board equipment, or alternatively, the ADS-B equipment may be a separate avionics unit.

Note: Definitions of acronyms (e.g., MOPS, ADS-B, 1090ES) and of many other terms (e.g., "Extended Squitter") can be found in Appendix B of these MOPS. Throughout this document, the term "TIS-B" refers to the Fundamental TIS-B Service as defined in the TIS-B MASPS, RTCA/DO-286B, §1.4.1. The acronym "ADS-R" refers to the ADS-B Rebroadcast Service as defined in the TIS-B MASPS, RTCA/DO-286B, §1.4.1. The Fundamental TIS-B Service provides traffic information that is derived from ground surveillance (e.g., radar) systems. The ADS-B Rebroadcast Service provides the Rebroadcast on 1090 MHz of an ADS-B Message from an alternate data link using the same TYPE Codes and Message Formats as are defined for Downlink Format (DF) = 17 ADS-B Messages, with the exception of bits modified as identified in §2.2.18.

Compliance with these standards by manufacturers, installers and users is recommended as one means of assuring that the equipment will satisfactorily perform its intended functions under conditions encountered in routine aeronautical operations. The regulatory application of these standards is the responsibility of appropriate government agencies. For example, in the United States, the Federal Aviation Administration (FAA) publishes and maintains a Technical Standard Order (TSO C166) for 1090ES ADS-B equipment to reference the requirements and bench test procedures in Section 2 of this document. In the European Union, the European Aviation Safety Agency (EASA) publishes and maintains a Eurpoean Technical Standard Order (ETSO C166) for 1090ES ADS-B equipment to reference the requirements and bench test procedures in Section 2 of this document.

Since the equipment implementation includes a computer software package, the most recent version of the Software Considerations in Airborne Systems and Equipment Certification, (RTCA DO-178B/EUROCAE ED-12B) is applicable. When determining the level of software requirements, as defined in RTCA DO-178B/EUROCAE ED-12B, or subsequent versions, the equipment manufacturer should consider the criticality appropriate for the installation certification, equipment failure analysis, and the fault monitoring being accomplished.

In addition, since the measured values of equipment performance characteristics may be a function of the measurement method, standard test conditions and methods of test are recommended in this document.

Section 1 of this document provides information and assumptions needed to understand the rationale for equipment characteristics and requirements stated in the remaining sections. It describes typical equipment applications and operational goals and, along with RTCA DO-242A, Minimum Aviation System Performance Standards for ADS-B, forms the basis for the standards stated in Sections 2 and 3.

Section 2 contains the minimum operational performance standards for the equipment. These standards define required performance under standard operating conditions and stressed physical environmental conditions. Also included are recommended bench test
