【 摘 要 】

This paper analyses CAN bus utilisation, complying with the CANaerospace protocol, in on-board aircraft electronic systems. The article briefly compares buses used on aircraft board, explains CAN bus applications and selection methods for different bus communications. Then it describes the mathematical analysis of bus capacity and bus utilisation, proposes a time schedule for transmitting and receiving messages and analyses the proposed time schedule. The main focus of the article is on testing the communication behaviour quality of the proposed aviation system with specific conditions for transmitting individual messages, carrying flight and aircraft parameters, complying with the CANaerospace specification. It is a modular system, where each module represents an intelligent aircraft device. Testing is focused on verification of correct entry of individual messages into the communication system.
