What does load stability mean in sling-load operations?

• A. The load remains centered and balanced, showing minimal sway or oscillation during lift
• B. The load is perfectly still at all times
• C. The load must always have some sway to verify action
• D. The load must not swing but can rotate

Answer: (A)

Load stability in sling-load operations means the load remains centered and balanced under the sling, showing minimal sway or oscillation during lift. When the rigging is proper and the load’s center of gravity aligns with the helicopter’s centerline, the pendulum effect is minimized, making control easier and reducing stress on the rigging and flight path. Some slight motion is normal due to wind and rotor wash, but the goal is a small, predictable swing rather than erratic movement. It’s not about being perfectly still at all times, nor about requiring constant sway or allowing uncontrolled rotation. The safer, more controllable condition is a balanced load that stays in a stable, centered position with minimal sway.
