Why might you adjust ballast or fuel when carrying external cargo or passengers in a UH-60?

• A. To adjust for loop stability during flight.
• B. To reduce cabin noise.
• C. To ensure weight distribution and CG stay within limits.
• D. To increase cargo capacity.

Answer: (C)

Weight distribution and center of gravity management is what this question is about. In a UH-60, how the weight sits relative to the rotor systems determines stability, control feel, and safety. When you add external cargo or passengers, you change the aircraft’s weight and where that weight is located. If the weight shifts too far forward, aft, left, or right, the center of gravity can move outside the approved limits, making the helicopter harder to control or affecting rotor/tail rotor authority. Using ballast or adjusting fuel helps move the weight back into the allowed CG envelope. Ballast places additional weight at specific locations to shift the CG as needed; fuel distribution can also shift the CG since tanks are in known positions and fuel can be allocated (or reduced) to move the CG forward or aft. The goal is to keep the CG within the published limits to maintain predictable handling, stability in hover and maneuvers, and overall flight safety. Other options don’t address weight distribution. Adjusting ballast or fuel specifically targets keeping the CG in bounds rather than changing noise levels, increasing cargo capacity, or other unrelated effects.
