Data link system between an aircraft and the ground and procedure for recovering from a failure

摘要

The present invention relates to a data link system between an aircraft and at least one ground station comprising an on-board assembly, a ground-air assembly, a land-based assembly, the last two assemblies being composed of sub-networks interconnected by routers and acting as the medium for distributed applications, the on-board assembly comprising a first (10) and a second (11) application computer. These two computers (10, 11) are distinct and interchangeable and receive both the same data supplied by the on-board user interface (12) and the same data supplied by an interface (13) with the ground-air sub-network access processor or processors (14) on the ground user side.
