2024年11月20日 · A664 has effectively replaced A629 as the high bandwidth bus.) In the real world of an aircraft "network" it is common to use use two or more network types and have data move across them all. An aircraft has many sensors that provide everything from a small data stream of a few hundred bits/sec to video streams of MBits/sec.

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.

2016年10月17日 · I want to know the difference between CAN and ARINC, I'm confused about their usage. For example, the communication between the cockpit and the controllers is done using ARINC protocols.

2017年11月6日 · 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. But we can look at its functions to see which domain would apply if they were implemented on an A664 network. The A664P5 descriptions are:

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.

2020年1月30日 · So the big change with the 787 was moving from the Honeywell AIMS and A629 based network to the Collins/GE A651 and A653 based Common Core System and A664 based network. The result of that platform change is why the flight decks look so different and that's what you see in the videos.
