When choosing between external single-point and dual/multi-point sling loads, what is a key consideration?

When choosing between external single-point and dual/multi-point sling loads, what is a key consideration?

• A. Crew experience
• B. Flight duration
• C. Load distribution and stability
• D. Noise level during lift

Answer: (C)

Load distribution and stability determine how a sling load behaves once lifted. When you use a single-point sling, all the lift force concentrates at one attachment. That creates a pendulum-like effect: as the helicopter maneuvers or encounters gusts, the load tends to swing or rotate more, making control harder and increasing the risk of instability or contact with the aircraft or load itself. Using dual or multi-point attachments spreads the lift across several points. This distributes forces more evenly, reduces swinging and tilting, and helps keep the load oriented more predictably relative to the helicopter. The result is greater stability, smoother handling, and safer lift dynamics, especially with heavier or irregular-shaped cargo. Other factors like crew experience, flight duration, or noise might influence planning or comfort, but they don’t directly govern how the load behaves in flight. So, stability and how the load shares the lift are the critical considerations when choosing between single-point and multi-point sling configurations.
