Which statement describes the effect of insufficient tension on sling load rigging?

Which statement describes the effect of insufficient tension on sling load rigging?

• A. The load remains perfectly still, increasing precision.
• B. The load can shift, causing instability during flight.
• C. The aircraft becomes more stable.
• D. No effect on flight.

Answer: (B)

In sling load operations, tension in the rigging lines acts to constrain the load and dampen its movement. If that tension is insufficient, the lines become slack, and the load behaves like a pendulum. Any gust, rotor wash, or maneuver can cause the load to swing fore‑aft or side‑to‑side, shifting the coupled center of gravity and altering how the helicopter responds. This leads to instability during flight rather than a steady, predictable lift. So the statement that the load can shift, causing instability during flight is the best description. The other options imply the load stays motionless, improves stability, or has no effect, which isn’t accurate when lines are slack.
