Which is NOT a TDP size listed?

• A. 40m-UH-1
• B. 25m-OH58
• C. 50m-UH-60
• D. 125m-sling using long lines

Answer: (A)

TDP sizes are standard distances used for planning sling-load transfers with specific helicopter configurations. In the training material, the listed pairings show 25 meters for the OH-58, 50 meters for the UH-60, and 125 meters when using long-line/sling configurations. A 40-meter distance paired with UH-1 is not part of the listed standards, so it isn’t a valid TDP size in the given options. That’s why the 40m-UH-1 is the correct pick for “not listed.”
