The invention relates to a flight-information data-sharing switching exchanger and a processing method thereof, belonging to the technical field of civil aviation. The flight-information data-sharing switching exchanger comprises a power supply, a microprocessor, a data communication unit, a data-sharing service unit, a data exchange module, an exchange management module and an enterprise service bus (ESB), wherein the microprocessor is connected with the data communication unit, the data-sharing service unit, the data exchange module and the exchange management module by the ESB; and the data communication unit is connected with an integrated metadata and separate data server of flight information. The processing method is realized by that the flight-information data-sharing switching exchanger is connected with the integrated metadata and separate data server of the airline company, airport and air-management flight information into a whole for communicating, sharing, exchanging and maintaining data and realizing data sharing and exchange among all civil aviation parts. The invention realizes the sharing management and exchange of data sources and has the advantages that the shared service data are reliably transmitted in a plurality of directions in real time, and decision support, emergency command, and the like are provided.
