Which of the following is false about the sling-leg arrangement?

• A. Forward outside, rear inside
• B. Rear outside, forward inside
• C. Both outside
• D. All sling legs are inside

Answer: (D)

The idea behind sling-leg arrangement is to place the lifting straps so the load stays balanced and clear of the helicopter and rotor wash. You’ll often see legs positioned in combinations of forward/back and inside/outside relative to the aircraft to create stability and control the load’s swing.

Saying that all sling legs are inside is not correct because having every leg toward the centerline reduces lateral stability and can bring the sling lines too close to the helicopter or to each other, increasing the risk of interference and improper load behavior in flight. In practice, you’ll have at least one leg outside or a mix of outside and inside positions to maintain proper clearance and balance. The other described configurations—forward outside with rear inside, or rear outside with forward inside, and even both outside—are consistent with how sling loads are arranged to achieve stable flight.
