A transmission system for avionics application data is disclosed. In one aspect, the system is for transmitting avionics application data between data producing means and data consuming means, the application data being transmitted in the form of data transmission units, each including: at least one portion of an application message, and an additional message containing identification and control information. The additional message includes: an identification sequence including a static part making it possible to identify the application message and its source and a variable part making it possible to distinguish the message in a unique manner, and a control sequence designed to check the integrity of the application message and based on a sequence representing a cyclic redundancy control code of the concatenation of at least one portion of the application message corresponding to said unit, with the identification sequence.
