Full title and description

DO-282B — Minimum Operational Performance Standards (MOPS) for Universal Access Transceiver (UAT) Automatic Dependent Surveillance—Broadcast (ADS‑B). This document defines the performance, message formats, radio/link requirements and test procedures for airborne UAT equipment supporting ADS‑B, Flight Information Service—Broadcast (FIS‑B), Traffic Information Service—Broadcast (TIS‑B) and related UAT services.

Abstract

DO-282B (Edition B, issued December 2, 2009) provides the Minimum Operational Performance Standards for UAT-based ADS‑B systems. It specifies equipment performance requirements, message and protocol definitions, interference and coexistence considerations, and test methods. Corrigendum 1 (issued December 13, 2011) was published to correct and clarify certain technical details and is incorporated in the DO-282B distribution.

General information

• Status: Published (DO-282B, Edition B). Corrigendum 1 (Dec 2011) issued; the DO-282 family has later revisions (DO-282C published 2022) for more recent MOPS updates.
• Publication date: December 2, 2009 (DO-282B); Corrigendum 1 issued December 13, 2011.
• Publisher: RTCA, Inc. (Committee SC‑186).
• ICS / categories: Aviation / Avionics / Air traffic management / Radio communications / Aeronautical data links (ADS‑B, UAT).
• Edition / version: B (DO‑282B) with Corrigendum 1 incorporated (2011).
• Number of pages: 704 pages (full DO‑282B volume).

Scope

Defines MOPS for airborne Universal Access Transceiver (UAT) equipment to support ADS‑B and associated UAT services. The scope covers physical layer and link-layer functions, message sets and formats, performance limits, interference/coexistence criteria, equipment test procedures and verification methods required for certification/acceptance as ADS‑B/UAT capable equipment. Section 2 (Equipment Performance Requirements and Test Procedures) is a primary normative section referenced by regulatory material.

Key topics and requirements

• UAT radio physical-layer specifications (frequency, transmitter/receiver characteristics, spectral masks).
• ADS‑B message structure and encoding for UAT (message types, fields, integrity checks).
• Performance requirements: update rates, latency, position accuracy, integrity and availability targets for ADS‑B applications.
• Interoperability and coexistence with other ADS‑B link technologies (coordination with 1090ES/DO‑260 family where applicable).
• Equipment test procedures and conformance tests (laboratory and flight test methods defined in Section 2).
• Operational considerations for FIS‑B and TIS‑B delivery over UAT and capability expansion notes (e.g., future supplemental services).
• Installation and certification guidance references (used by certification authorities and TSO/TSO‑like approvals where referenced).

Typical use and users

Used by avionics manufacturers, equipment designers, test laboratories, certification applicants, system integrators, and regulators to design, verify, certify and procure UAT ADS‑B avionics. Also referenced by operators and airspace planners when assessing ADS‑B capabilities and compliance for aircraft equipping.

Related standards

Closely related to RTCA DO‑260 / DO‑260B / DO‑260C (1090 MHz ES ADS‑B MOPS) and later DO‑282C (UAT MOPS update, 2022). Referenced by FAA regulations and Technical Standard Orders (e.g., TSO C‑154 series) and incorporated by reference in applicable CFR sections governing ADS‑B equipment performance.

FAQ

Q: What is this standard?

A: DO‑282B is the RTCA Minimum Operational Performance Standard that defines the technical and test requirements for Universal Access Transceiver (UAT) implementations used for ADS‑B and related UAT services.

Q: What does it cover?

A: It covers UAT radio characteristics, message formats, equipment performance limits (accuracy, latency, availability), interoperability concerns, and detailed equipment test procedures (notably in Section 2) required for conformance and certification.

Q: Who typically uses it?

A: Avionics manufacturers, certification applicants, test laboratories, integrators, and regulatory authorities use DO‑282B when developing, testing or certifying UAT ADS‑B avionics. Operators and airspace planners consult it for capability and compliance assessments.

Q: Is it current or superseded?

A: DO‑282B (2009) with Corrigendum 1 (2011) remains an important historical MOPS document, but the DO‑282 family was later updated (DO‑282C published in 2022) to reflect newer requirements and clarifications. Users requiring the latest regulatory MOPS should confirm which revision (B vs C) is mandated by the applicable authority or TSO.

Q: Is it part of a series?

A: Yes — DO‑282 is part of the RTCA ADS‑B/aviation datalink MOPS family and is closely associated with the DO‑260 series (1090 MHz ES ADS‑B MOPS). Revisions and corrigenda are published as needed (e.g., DO‑282A, DO‑282B, Corrigendum‑1, DO‑282C).

Q: What are the key keywords?

A: ADS‑B, UAT, MOPS, RTCA, Corrigendum, FIS‑B, TIS‑B, ADS‑B Out, avionics, equipment performance.
