ARINC 664:Enhancing communication and Safety in the B787 Dreamliner

ARINC 664, also known as Avionics Full-Duplex Switched Ethernet (AFDX), is a networking system used in the Boeing 787 (B787) aircraft. This system provides a high-speed, deterministic, and reliable communication network between various avionics subsystems on the aircraft. The introduction of ARINC 664 in the B787 brings several advantages. Firstly, it simplifies the wiring and interconnection complexity by utilizing a single Ethernet network for multiple subsystems. This reduces weight, complexity, and maintenance requirements. Secondly, ARINC 664 ensures reliable and real-time communication by implementing Quality of Service mechanisms. Critical data, such as flight control commands, receives higher priority and is delivered within specific timing constraints. This guarantees the safety and efficiency of the aircraft's operations. Lastly, the ARINC 664 system in the B787 provides redundancy and fault tolerance through dual-redundant Ethernet switches and multiple network paths. This enhances system reliability and fault recoverability, ensuring continuous operation even in the event of component failures. Overall, the introduction of ARINC 664 in the B787 aircraft offers simplified wiring, real-time communication, and enhanced reliability. These benefits contribute to the overall safety, efficiency, and performance of the B787 during flight operations.
