By processing the wind tunnel virtual flight test data, the movement process of the fly-by-wire civil aircraft can be realistically simulated. This paper establishes the dynamic model of the fly-by-wire civil aircraft wind tunnel virtual flight, designs the aircraft's longitudinal and lateral heading control laws, and verifies the correctness of the test results by comparing the simulation data with the flight test data. The digital filter is used to eliminate the noise of the test data, and the data compatibility test is performed by the output error method to eliminate the constant error and the scale factor error in the flight test data. A set of virtual flight data processing methods for fly-by-wire civil aircraft in wind tunnels has been formed.
