This paper described the composition, principle of Jack for aircraft center of gravity measurement system, and analyzed the factor that the winding deformation of wing and fuselage during the Jack goes up;that support points' relative location changes during the process of aircraft weighing posture adjustment.The influence of lateral force on the measurement accuracy of the system, put forward to effective measures for eliminating and reducing lateral force on the measurement accuracy of the system influence.
