Arinc 664 Introduction

Introduction to ARINC-664 part 7 (Tutorial video)



ARINC-664 p7, commonly referred to as AFDX (Avionics Full-Duplex Switched Ethernet) is an avionics communications bus that has been mandated by both Boeing and Airbus for use in new civilian avionics designs. . It is based on Ethernet technology but modified to provide deterministic, high-speed data transmission for aviation applications.

Arinc 664 (AFDX) implements a dual-redundant network architecture and uses Virtual Links to manage network traffic, ensuring guaranteed bandwidth and maximum latency for critical avionics messages. The protocol supports different levels of message priority and allows precise control over bandwidth allocation.

Arinc 664 switched network topology helps contain faults and prevents them from propagating throughout the entire system. It promotes standardization across different aircraft systems and manufacturers, facilitating easier integration and maintenance.

The protocol is scalable, supporting a large number of network nodes and high data rates, making it suitable for complex avionics architectures.

Arinc 664 is designed to meet stringent aviation safety standards and can be certified for use in safety-critical applications. Its adoption has contributed to the advancement of avionics systems, enabling more sophisticated and integrated aircraft designs while maintaining high levels of safety and reliability.
