The ARINC 825 Standard

Print E-mail
  • Current commercial air transport aircraft system architectures have incorporated CAN as an ancillary subsystem bus to ARINC Specification 664, Part 7 (AFDX), networked Integrated Modular Avionics (IMA) architectures. For these aircraft, CAN has been used to link sensors, actuators and other types of avionics devices that typically require low to medium data transmission volumes during operation. In this role, CAN complements higher capacity networks that support systems controlling the flight deck information flow and presentation. In contrary, General Aviation system architectures employ CAN as one of the major avionics buses or even as the avionics backbone network. In this role CAN may have to fulfill all requirements of a flight safety critical network. The ARINC Specification 825 enhances CAN to create a network that embraces both philosophies and has been developed by the Network Infrastructure and Security Committee of ARINC.
  • The ARINC825 standard (General Standardization of Controller Area Network Bus Protocol for Airborne Use) was driven by Airbus and Boeing and defines a communication standard for airborne systems using Controller Area Network (CAN), which has been identified by both leading airframers as an important baseline network for their future transport aircraft.
  • ARINC825 was developed by the CAN technical working group of the Airlines Electronic Engineering Committee (AEEC) Aircraft Network Infrastructure and Security Subcommittee that included members from Airbus, Boeing, Rockwell Collins, GE Aerospace and Stock Flight Systems.
  • ARINC825 will be the CAN standard for all future Airbus and Boeing aircraft. Offering a high degree of compatibility with the widely accepted CANaerospace standard, ARINC825 is applicable to General Aviation aircraft as well.
  • ARINC825 is the framework for all future ARINC standards based on CAN like the ARINC specification 826 (software dataload) and the ARINC specification 812 (Galley Insert Communication).
  • ARINC825 is doumented on Wikipedia  in English and German.
  • Innovative Control Systems, Inc. , Stock Flight Systems and Wetzel Technology  have turned the original hardware/software system which was used to ensure the consistency and integrity of the ARINC specification 825 during the standardization process, into a set of products suitable for ARINC825 system designers, equipment vendors, aircraft OEMs and airlines.
