Which statement is true regarding helicopter weight and balance?

• A. Regardless of internal or external loading, lateral axis CG control is ordinarily not a factor in maintaining helicopter weight and balance
• B. The moment of tail-mounted components is subject to constant change
• C. Weight and balance procedures for airplanes generally also apply to helicopters
• D. Helicopters require completely different weight and balance procedures

Answer: (C)

Center of gravity location is the key factor determining stability and controllability, and the overall approach to weight and balance hinges on that idea. In helicopters, as in airplanes, you determine total weight, calculate moments by multiplying each item’s weight by its arm, find the overall center of gravity, and ensure that both weight and CG lie within the published limits for safe flight. The same basic calculations and checks are used: track empty weight, add fuel and payload, compute the total weight and CG, and verify they fit the allowable envelope and maximum takeoff weight. Although rotorcraft have unique dynamic considerations due to the rotor systems, the fundamental concept and the general procedures for weighing and balancing carry over from airplanes, so airplane weight and balance practices generally apply to helicopters.
