In the implementation of the artificial ice flight test, artificial ice shapes must be installed to the test aircraft, which reduces the aerodynamic performance of the aircraft and leads to a high risk. In order to reduce the risk of artificial ice flight test, starting from the flight test requirements, this paper proposes a real-time comparative monitoring scheme of the design lift coefficient and the actual lift coefficient of the test aircraft, and develops a comparison model of aerodynamic coefficients accordingly. Verified by the flight test data, the model can figure out reasonable design lift coefficient and actual lift coefficient, which lays a foundation for the subsequent application in the artificial ice flight test.
