The invention relates to a method and a device for managing communication channels for data exchange from an aircraft (105) comprising means (115) for establishing at least one connection path between the aircraft and at least one ground entity (120) with a plurality of communication channels of at least two different types. After detecting an event such as the modification of a communication channel condition or a modification of the aircraft position, a communication configuration enabling the aircraft to receive or transmit data from or to the ground entity via at least one of said communication channels is determined. The means for establishing at least one connection path are then adapted based on the communication configuration. Advantageously, the transmission of at least one datum comprises determining the priority level of said datum and determining the type of communication channel of the connection path, the datum being transmitted if the determined type of communication channel is compatible with the priority level.

L'invention concerne un procédé et un dispositif de gestion de canaux de communication pour des échanges de données à partir d'un aéronef (105) comprenant des moyens (115) adaptés à établir au moins un chemin de connexion entre l'aéronef et au moins une entité au sol (120) selon une pluralité de canaux de communication d'au moins deux types différents. Après avoir détecté un événement tel que la modification de l'état d'un canal de communication ou la modification de la position de l'aéronef, une configuration de communication permettant à l'aéronef de recevoir ou de transmettre des données à l'entité au sol par l'intermédiaire d'au moins l'un des canaux de communication est déterminée. Les moyens adaptés à établir au moins un chemin de connexion sont alors adaptés selon la configuration de communication. Avantageusement, la transmission d'au moins une donnée comprend la détermination d'un niveau de priorité de cette donnée et la détermination du type de canal de communication du chemin de connexion, la donnée étant transmise si le type de canal de communication déterminé est compatible avec le niveau de priorité.
