What is the purpose of a loading graph?

The purpose of a loading graph centers around its ability to help visualize the effects of different loading scenarios on the center of gravity (CG) location. By representing various weight configurations of an aircraft, the loading graph allows pilots and ground crews to see how the distribution of weight, whether it's passengers, cargo, or fuel, influences the CG.

Understanding CG is critical for safe aircraft operation because it affects stability and control during flight. If the CG is outside the acceptable limits, it can lead to challenges in handling the aircraft, potentially leading to adverse flying conditions. Therefore, the loading graph serves as a vital tool that enhances situational awareness regarding aircraft balance, thereby ensuring compliance with safety parameters.

Other choices do not pertain to the primary function of a loading graph; they represent separate aspects of flight and operational considerations that are important but distinct from weight and balance calculations related to CG.
