Which statement is a weather and visibility related limitation for sling load operations?

• A. The weight of the load is restricted to the aircraft's operating capability.
• B. Atmospheric conditions (pressure, altitude, temperature, and winds) affect the helicopter's lift capacity.
• C. Adverse weather and darkness (low visibility) may limit sling load operations.
• D. A limited number of helicopters are available for sling load missions.

Answer: (C)

Weather and visibility directly affect the safety and feasibility of sling load operations. When conditions are adverse or it’s dark, pilots can’t see the load, the drop/landing zone, or obstacles well enough to guide the load precisely, increasing the risk of swing, contact with obstacles, or misplacement. That makes operations unpredictable and often unsafe, so adverse weather and darkness may limit when sling loads can be performed. The other factors mentioned are about general aircraft performance or resource constraints (weight limits tied to aircraft capability, lift capacity under changing atmospheric conditions, or the number of helicopters available), not specifically about weather and visibility.
