ARINC 825 is a standard for Controller Area Network bus protocol for airborne use. ARINC 826 is a protocol for avionic data loading over a Controller Area Network bus. ARINC 827 specifies a crate format for electronic distribution of software parts for aircraft.
The ARINC 429 unit of transmission is a fixed-length 32-bit frame, which the standard refers to as a 'word'. The bits within an ARINC 429 word are serially identified from Bit Number 1 to Bit Number 32 [4] or simply Bit 1 to Bit 32. The fields and data structures of the ARINC 429 word are defined in terms of this numbering.
AFDX adopted concepts such as the token bucket from the telecom standards, Asynchronous Transfer Mode (ATM), to fix the shortcomings of IEEE 802.3 Ethernet. By adding key elements from ATM to those already found in Ethernet, and constraining the specification of various options, a highly reliable full-duplex deterministic network is created providing guaranteed bandwidth and quality of service ...
The Bosch CAN specification itself allows messages being transmitted both periodically and aperiodically but does not cover issues like data representation, node addressing or connection-oriented protocols.
SCADE Solutions for ARINC 661 allow creating both ARINC 661-compliant CDS and UA. For CDS developers, the toolchain features a complete customizable ARINC 661 compliant model-based widgets library and the automated generation of a portable ARINC 661 server, compliant with the DO-178B/DO-178C safety objectives up to level A. For UA developers ...

ARINC 826 is a protocol for avionic data loading [1] over the Controller Area Network as internationally standardized in ISO 11898-1. It allows Loadable Software Aircraft Parts to be loaded in a verifiable and secure manner to avionics Line Replaceable Units (LRUs) and Line Replaceable Modules (LRMs) using CAN.
The cable is used for signal transmission and at the same time for power supply (30 V). The communication electronics and participants with low power requirements, like light beams, can be powered directly. Consumers with a higher energy requirement, such as valve terminals, can use a separate, usually black flat cable for power supply (30 V).
