Abstract: A method for applying a plurality of vehicles each including an onboard server and at least two apparatuses, an onboard server and each of the apparatuses storing initial data, each onboard server being connected to the apparatuses mounted in the same vehicle with a local network. The method includes the steps of transferring modified data, through an extended radiofrequency communication network, from a server on the ground towards the onboard servers, when the modified data have been stored in memory in each onboard server, emitting via the extended network, an updating command, and transmitting modified data to at least one apparatus through the corresponding local network, the modified data replacing, in said apparatus, the initial data.
