Landing Point Size 4 is associated with which helicopters?

• A. UH-60
• B. UH-1
• C. OH-58
• D. CH-47/CA-53/H-3

Answer: (D)

Landing Point Size is the amount of space needed for a helicopter to touch down and lift off safely, accounting for rotor diameter, rotor wash, and clearance from obstacles. Heavier, larger rotorcraft require more room, so they fall into bigger size categories. Landing Point Size 4 is the designation for the larger, heavy-lift helicopters, such as the CH-47 Chinook and its equivalents (CA-53 Sea Stallion and H-3 Sea King). Their wide rotor discs and greater clearance needs demand that bigger landing area. Lighter helicopters like the UH-60, UH-1, and OH-58 need smaller sizes, which is why size 4 is associated with CH-47/CA-53/H-3.
