2016年10月17日 · ARINC 629: Used on the 777, it increased speed over 429 (2 Mbps) and increase the receiver count to 120. It works on half duplex, allowing single interface to send and receive data. ARINC 664 / AFDX: Developed by Airbus, Avionics Full-Duplex Switched Ethernet is used on newer aircraft like A380. Can use commercial off the shelf hardware.

2020年8月18日 · I haven't worked with ARINC 664/ADFX specifically, but my understanding is that aircraft use specific ADFX switches. From Wikipedia : Since AFDX utilizes the Ethernet protocol at the MAC layer, it is possible to use high performance COTS switches with Layer 2 routing as AFDX switches for testing purposes as a cost-cutting measure.

2024年11月20日 · Wondering if ARINC-664 (and ARINC-629) have backwards combability with ARINC-429. I realize -664 uses Ethernet while -429 is implemented using a two-wire data bus. However, wanted to see if any of the 32-bit ARINC-429 are "ported" upwards.

2017年7月11日 · The primary reason for moving away from ARINC-429 is that it is a single transmitter/multiple receiver architecture. This results in a large amount of physical wire. That adds weight and requires maintenance. A bus such as ARINC-664, which is based on Ethernet, can significantly reduce wire.

2019年6月14日 · For instance all fly by wires computers on Airbus 320, 330, 340 use arinc 429 protocol. Nowadays other protocols do exist too such as arinc 629 protocol or fiber optic protocols etc. As a summary all aircraft systems that need to transmit and receive binary data may use 429 protocol, but other digital protocols are possible.

2017年11月28日 · There are some resources. This source shows how AFDX is used as the backbone of the IMA (Integrated Modular Avionics) and lists subsystems such as the air data inertial reference units (ADIRU), Engine Electronic Controllers (EEC) and Electrical Load Management (ELM) Systems as 'members' of the network.

2018年6月10日 · ARINC 664 is a switched Ethernet type of bus with each A664 end system connected directly to a network switch, so there is no contention for media access at the end system. All network access control is controlled within the switches. Beyond the IMA switches, the network typically has 4 or 6 remote switches spread along the aircraft.

2024年4月16日 · Wondering if ARINC-664 (and ARINC-629) have backwards combability with ARINC-429. I realize -664 uses Ethernet while -429 is implemented using a two-wire data bus. However, wanted to see if any of the ...

2017年7月24日 · And in a similar vein, the B787 IMA contains "GPMs" or General Processing Modules. It also contains two ARINC 664 network switches (network I/O for the cabinet). There are no direct legacy connections to the GPMs. Legacy (ARINC 429, CAN, discrete, analog) buses are connected to the external ARINC 664 network using Remote Data Concentrators (RDC).

2017年11月6日 · As @Bluephoenix mentioned, the security domains are defined in ARINC 664 Part 5. These domains specifically apply to ARINC 664 networks, though the concepts can be applied to other networks. You also reference a Cabin Intercommunication Data System (CIDS) which is an Airbus specific system in the A320 series -- which does not have an A664 network.
