ARINC SPECIFICATION 826-1-2013 PDF

Full title and description

St ARINC SPECIFICATION 826-1-2013 — ARINC specification number 826-1 published in 2013. This specification defines requirements, interface characteristics and implementation guidance for the 826-1 family of avionics system interfaces and protocols used for onboard communication, data exchange and equipment interoperability in transport-category aircraft.

Abstract

ARINC 826-1 (2013) is a technical standard produced under the ARINC/AEEC framework that provides a structured set of requirements and recommended practices for the design, testing and integration of avionics equipment and subsystems that implement the 826-1 interface. The document addresses message formats, timing and electrical/physical interface considerations, validation and verification activities, and guidance for achieving interoperability between line-replaceable units (LRUs), sub-systems and ground tools.

Scope

This specification applies to the definition, implementation and verification of the ARINC 826-1 interface for airborne equipment. It covers interface data structures and message semantics, timing and synchronization requirements, error handling, environmental and electrical constraints where applicable, and recommended test procedures to demonstrate compliance and interoperability in aircraft installations. It is intended for use by avionics equipment manufacturers, system integrators, airlines and certification authorities when specifying or accepting LRUs and sub-systems that claim compliance with 826-1.

Key topics and requirements

• Formal definition of the 826-1 message and data formats, including required fields and optional extensions.
• Timing, sequencing and synchronization rules for reliable data exchange among LRUs and systems.
• Electrical and physical interface considerations (signal levels, connector types, grounding and isolation notes — where applicable).
• Protocol state machines and error detection/recovery behavior.
• Conformance and interoperability test procedures, including recommended test vectors and acceptance criteria.
• Guidance for software and hardware implementation to support certification and maintainability.
• Compatibility notes with related ARINC and industry standards (interface mapping, gateway behaviors).

Typical use and users

Primary users include avionics engineers, system architects, hardware and firmware developers, test engineers, aircraft manufacturers (OEMs), airlines specifying equipment, and certification/airworthiness authorities. Typical use cases are: defining the interface contract for LRUs, developing equipment firmware to meet 826-1 messaging requirements, creating test plans to demonstrate interoperability, and integrating equipment from multiple suppliers into a common aircraft communications architecture.

Related standards

ARINC 826-1 is typically used in conjunction with other avionics standards and industry guidance such as ARINC 429 (data bus), ARINC 664 / AFDX (deterministic Ethernet for avionics), ARINC 615/615A (mass memory / data loading), ARINC 818 (avionics video), and RTCA/DO standards for environmental and software assurance (for example DO-160 and DO-178 series). System integrators often cross-reference these documents when specifying complete avionics solutions.
