Which TDP size corresponds to 100m-sling and unknown A/C?

• A. 25m-OH58
• B. 50m-UH-60
• C. 150m-sling using long lines
• D. 100m-sling and unknown A/C

Answer: (D)

The concept being tested is choosing a sling-load configuration that stays safe and workable when you don’t know which helicopter will carry the load. In sling-load planning, the sling length and the aircraft type matter for clearance, rotor wash effects, and how the load behaves in flight. When the aircraft isn’t identified in advance, you want a configuration that is compatible with multiple platforms and doesn’t rely on a specific helicopter model. Choosing a 100-meter sling with an unknown aircraft is the best fit because it uses a standard, versatile sling length that works for a range of helicopters and doesn’t depend on the capabilities of a particular aircraft. The other options tie the sling to a specific helicopter type or to a long-line method, which isn’t guaranteed when the A/C is unknown. The 100-meter baseline provides the most flexible, broadly applicable option, making it the sensible choice when aircraft are not known ahead of time.
