Which rear link count is specified for a three-fuel blivet?

• A. 30 Links
• B. 45 Links
• C. 55 Links
• D. 60 Links

Answer: (C)

In sling-load rigging, the rear link count sets how long the rear portion of the sling is to place the load in the correct geometry for a stable lift. A three-fuel blivet is a larger, heavier configuration, so the sling must be extended enough to keep the center of gravity under the helicopter’s hook and to maintain proper line angles that minimize pendulum motion. Fifty-five links give the right balance for this load, aligning the load’s lift points with the helicopter’s lift line and keeping the load from riding nose-up or tail-down during the hoist. Too few links would shorten the sling and distort the angles, making the load unstable or harder to control; too many links would make the sling too long, increasing swing and risking contact with the rotor or ground. So, fifty-five links is the appropriate rear link count for a three-fuel blivet.
