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.
