What is 'tensioning' in sling load operations?

• A. Releasing all tension to allow movement.
• B. Applying controlled tightness to rigging to remove slack and stabilize the load.
• C. Attaching the load to the helicopter.
• D. Checking the weather conditions before lift.

Answer: (B)

In sling load operations, tensioning means applying controlled tightness to the rigging to remove slack and stabilize the load. By tightening the lines in a careful, progressive way, you eliminate loose slack that would let the load swing or shift during flight. This helps the load track straight and reduces pendulum-like motion, making the lift safer and easier for the pilot to manage. The goal is to achieve even tension across all suspension points and correct line angles before flight, so the load behaves predictably under lift and during maneuvers. Releasing all tension would create slack and instability, attaching the load to the helicopter is a separate setup step, and checking weather conditions is about planning, not tightening and stabilizing the load.
