G L Marion: 2162. Basic Principles of Weight and Balance. 1993.



Knowledge of the basic principles of weight and balance will lead to better understanding of aircraft loading. This should allow for the control of the Center of Gravity (CG) within the aircraft’ s safe loading range. Controlling the CG within the safe loading range will have an effect on the pitching moment of the aircraft and thus an effect on induced drag. Effecting induced drag is relative to thrust setting and fuel burn. Shifting the CG as far aft as possible in the safe loading range could see reductions in fuel consumption ranging from ,05% to .2% for each percent mean aerodynamic chord (MAC) shift aft. Although the percentages may be small they are significant when considering total fleet fuel.
