Flight simulation data processing method and device

The embodiment of the invention provides a flight simulation data processing method and device which are applied to a server of a flight simulation system. The method comprises the following steps: counting the data volume of trajectory data generated by server simulation, and, according to the counted data volume, determining whether track data generated by server simulation is subjected to sampling processing or not, so when the data volume is large, the data volume of the trajectory data sent to the client is reduced, the data volume refreshed by the client is further reduced, the situationthat the refreshing performance of the client occupies too much and gets stuck is reduced, and due to the fact that the data volume needing to be rendered is reduced, the rendering speed is increased, and it is guaranteed that the rendering speed can follow the refreshing speed. Furthermore, track monitoring is matched with curve monitoring, table monitoring and/or virtual flight attitude instrument monitoring for use, s
