What is the chain length for both sling sets?

• A. 8 ft
• B. 6 ft
• C. 9 ft
• D. 10 ft

Answer: (A)

The main idea is that sling-load rigging uses fixed, equal chain lengths to establish proper lift geometry and control during the hoist. When both sling sets use the same chain length, the load hangs level and stays balanced, which minimizes side-to-side sway and keeps the load within safe lift angles. Eight feet is the standard length because it provides the right height from the load to the helicopter to maintain adequate clearance from rotor wash and structure, while also keeping the rigging points at the correct height for stable support. If the chains were shorter, the load could ride too close to the aircraft and be harder to control; if they were longer, the load could lift higher and swing more, increasing the risk of contact with the aircraft or ground and making handling more difficult. So eight feet gives the best balance for both sling sets, promoting stable, predictable lifting.
