Which TDP size corresponds to 125m sling using long lines?

• A. 25m-OH58
• B. 100m-sling and unknown A/C
• C. 150m-sling using long lines
• D. 125m-sling using long lines

Answer: (D)

In sling-load planning, the TDP size is matched to the actual sling length and whether long lines are used. When the configuration specifies a 125-meter sling with long lines, the corresponding TDP is the 125m-sling using long lines. This alignment ensures the rigging, load geometry, and flight characteristics (like clearance and stability) are consistent with what the aircraft and line configuration can safely handle. The other options describe different sling lengths or aircraft scenarios that don’t match the given setup, so they wouldn’t reflect the correct rigging parameters for a 125-meter long-line sling.
