What length in meters is required for a size 2 TDP?

• A. 50 m
• B. 25 m
• C. 80 m
• D. 35 m

Answer: (D)

In LZ/PZ planning, the space allocated for a Tactical Drop Point scales with aircraft size to provide safe approach, touchdown, and rotor and ground-crew clearance. For a mid-size, size 2 TDP, the standard length is 35 meters. That length gives enough room for the helicopter to align and settle, while still leaving a margin for rotor wash and safe exit/entry operations. Longer lengths (50 or 80 meters) are used for larger configurations or additional safety margins, and shorter lengths (25 meters) wouldn’t provide adequate space for a proper touchdown in a typical mid-size helicopter operation. So, 35 meters is the appropriate length.
