Which statement best describes how center-of-gravity control affects flight?

• A. It keeps the helicopter balanced and prevents excessive pitch or roll
• B. It increases lift without increasing load stability
• C. It makes the helicopter more prone to sway
• D. It has no practical impact on sling-load operations

Answer: (C)

Center of gravity position determines how stable the helicopter is and how it responds to disturbances, especially in flights with a suspended load. In sling-load operations, the load acts like a pendulum hanging beneath the aircraft, so any shift in the helicopter’s stability or any disturbance can transfer into the load’s motion. If the center of gravity isn’t optimized, those disturbances and control inputs can amplify the load’s swinging, making the aircraft more prone to sway. That dynamic is why this statement best describes the effect of center-of-gravity control on flight. The other ideas aren’t as accurate in this context: CG doesn’t increase lift by itself, and while maintaining proper CG helps overall stability, the practical concern in sling-load flights is how CG affects susceptibility to sway. CG certainly has a practical impact on sling-load operations.
