This paper starts with the commonly used wheel method of aircraft center of gravity measurement, and analyzes the more convenient horizontal attitude measurement method derived from the wheel method in the practice of gravity measurement of a certain type of general aircraft. Then through practical application and data analysis, it is determined that the factor that has the greatest influence on the measurement accuracy in this method is the measurement error of the front and the main wheel track. Finally, a special tooling measurement method for accurate measurement of the wheelbase is proposed for this factor, which makes the measurement accuracy of the center of gravity of the aircraft effectively guaranteed.
