What is the TDP size for a Type 6 aircraft?

The TDP (Touchdown Point) size for a Type 6 aircraft is 125 meters. This dimension is significant because it ensures that the helicopter has a sufficient area to safely land and take off, accommodating the rotor wash and the size requirements necessary for that type of aircraft.

When determining the TDP size, factors such as the aircraft's weight, rotor diameter, and the environmental conditions of the landing zone are taken into account. A Type 6 helicopter generally falls into a category that supports operations in more confined or constrained environments, which is why a TDP size of 125 meters is appropriate. It provides adequate space for both the helicopter's landing footprint and the necessary safety margins around the touchdown point.
