Exploration of weight and center of gravity control for civil aircraft with auxiliary fuel tank installation

The weight and CG calculation is a necessary procedure before an aircraft takes off to ensure the CG of the aircraft is within its CG envelope. The CG within its CG envelope is safe for an aircraft in theory. When the Civil Aircraft adds an Auxiliary Fuel Tank System, the weight and CG of the aircraft will change, so the fuel consumption curve is different. Therefore, we must control it, ensuring that the weight and CG satisfy the operation request. The target of the aircraft loading and trimming sheet is to offer a tool that can be used to judge the CG simply and conveniently.
