4. A method of weighing and traversing an aircraft as claimed in claim 3, wherein: and seventhly, each datum comprises data of a single weighing sensor, a resultant force of the weighing traversing mechanism and the total weight of the airplane.
5. A method of weighing and traversing an aircraft as claimed in claim 4, wherein: and step seven, the gravity center calculation is further included.
6. A method of weighing and traversing an aircraft as claimed in claim 5, wherein: in the step eight, the control cabinet controls a lifting mechanism in the weighing assembly to enable the universal wheels on the base to be in contact with the ground; then pulling out the safety bolt and pulling a manual reversing valve in the hydraulic oil system to a zero position gear; operating a manual pump in the hydraulic oil system, and enabling an oil cylinder to act until an airplane wheel is in contact with the ground; and then sliding the equipment out of the airplane wheel by using the opening to finish the work of detaching the weighing and traversing mechanism from the airplane wheel.
