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.
Fuel Control and Monitoring System (FCMS) reports fuel remaining on board in a similar manner, but, by controlling pumps & valves, also manages fuel transfers around various tanks. Refuelling control to upload to a certain total mass of fuel and distribute it automatically. Transfers during flight to the tanks that feed the engines.
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 708 uses a data transfer method using transformer-coupled Manchester encoded signal, like the MIL-STD-1553 protocol. Termination of the bus is essential for good signal quality. Furthermore, the bitstream is continuous, requiring good re-synchronization to the bit stream.
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.
ARINC 828 specifies connectors, interwiring and signal types using MIL-DTL-38999 connectors which can be used to connect EFBs of all hardware classes with aircraft. ARINC 828 combines classical aircraft interfaces like discretes, ARINC 429 or ARINC 717 buses with PC technology like USB , DVI , LVDS , and Ethernet .
The ARINC 629 computer bus was introduced in May 1995 and is used on aircraft such as the Boeing 777, Airbus A330 and Airbus A340 [1] [2] as well as the Airbus A320 series. [ 3 ] The ARINC 629 bus operates as a multiple-source, multiple-sink system; each terminal can transmit data to, and receive data from, every other terminal on the data bus.
