Which type of aircraft can a size 3 TDP support?

• A. Small observation (any OH-## AC)
• B. Large utility/attack (UH-60, AH-64)
• C. Cargo (MV-22, any CH-## AC)
• D. Sling loads using long lines

Answer: (B)

A size 3 TDP is sized to accommodate medium to large rotorcraft, providing enough space for their rotor clearance, landing gear footprint, and safe approach/departure paths. That makes large utility/attack helicopters like the UH-60 Black Hawk and AH-64 Apache the best fit, since they require more room than small observation helos but don’t demand the largest cargo platforms. It wouldn’t be suitable for the biggest cargo/tiltrotor platforms, which need an even larger landing area, and sling-load operations are a capability rather than a type of aircraft. So the size 3 TDP is best matched to large utility/attack helicopters.
