Which aircraft types use TDP Size 2 with a diameter of 35 meters?

The designation of TDP Size 2, which has a diameter of 35 meters, is specifically relevant to certain types of helicopters that require this size for safe and efficient landing operations. The correct answer encompasses the AH-1W/Z and UH-1N/Y helicopters, both of which are designed to operate in environments that necessitate a TDP Size 2 landing zone.

The AH-1W/Z is a twin-engine attack helicopter known for its versatility in various combat scenarios, while the UH-1N/Y, commonly referred to as the "Huey," serves as a utility helicopter with various mission capabilities ranging from troop transport to medevac support. The requirement for a 35-meter diameter allows these helicopters to maintain stability and safety during landings and takeoffs.

Understanding the specific needs of these aircraft types in terms of landing zones is crucial for mission planning and operational effectiveness. Each helicopter's size, weight, and operational characteristics determine the appropriate TDP size, ensuring that helicopter crews can execute their missions safely, especially in complex environments.
