Which is a common effect of improper rigging on a sling-load?

• A. Load imbalance with excessive swing and potential failure of rigging components
• B. Faster flight with less drag
• C. Improved stability
• D. Reduced need for ground guides

Answer: (A)

When a sling-load isn’t rigged evenly, the load’s center of gravity becomes misaligned with the aircraft. This creates an imbalance that acts like a pendulum as the helicopter maneuvers, causing excessive swing. The swinging generates uneven, dynamic loads on the rigging components—snaps, links, slings, and straps—raising the risk of hardware failure or load loss. That’s why the other ideas aren’t correct: improper rigging doesn’t make the flight faster or reduce drag; it typically makes handling harder and can increase drag due to erratic movement. It also doesn’t improve stability; it degrades stability and control. And it doesn’t lessen the need for ground guides; in fact, it makes ground handling more risky, so guides are more important to safely attach and offload the load.
