ARINC-825 Insights

What is ARINC-825?

ARINC 825 is a data bus protocol used primarily in aerospace applications. It's based on the Controller Area Network (CAN) protocol and defines how data is exchanged between different avionics systems within an aircraft. It specifies the message format, data encoding, and communication protocols used for transmitting information such as sensor readings, control signals, and status updates between components like flight management systems, engine control units, and navigation systems.

What other technologies are related to ARINC-825?

ARINC-825 Competitor Technologies

UART/RS232/RS422/RS485

These serial communication protocols are used in embedded systems but offer lower performance and reliability than ARINC-825/CAN for avionics applications. Hence they are sometimes used when CAN is not available, making them competitors.
