A study of data processing and analysis in airspeed calibration using the tower flypast method

The airspeed calibration by tower flypast method is a convenient and effective method in airspeed calibration test flight. The principle and data processing process of the tower flypast method are introduced in detail. The influence factors of airspeed calibration by tower flypast method are studied and analyzed, and the influence quantity of these factors on airspeed calibration results is obtained. At the same time, the improvement measures and requirements are put forward to improve the accuracy of test flight results.
