Organization of the transmission of signaling messages in the computer networks of the aircraft

This article considers the problem of transmitting signal text messages in the onboard computer networks of an aircraft. The article provides a brief overview of promising areas in the design of modern avionics, such as integrated modular avionics and Avionics Full Duplex Ethernet. The text of the article provides a protocol that allows you to generate the text of the signal zone on the multifunctional indicator in the cockpit, as well as to transmit the encoded text using the Arinc 664 (AFDX) protocol. The use of this protocol makes it possible to transmit to the multifunctional indicator in the cockpit the zone of signal messages completely formed in the computing unit. The advantage of this approach is the absence of information fragmentation, and therefore an increase in the frequency of updating information on the indicator screen.
