What space is required for a helicopter to land safely?

• A. 50 feet with no restrictions
• B. 100 feet of clear area with nothing over 12 inches high
• C. 200 feet with any obstacle under 6 feet
• D. 500 feet of open space

Answer: (B)

Landing a rotorcraft safely requires a clearly defined, unobstructed area large enough to accommodate the rotor diameter, allow for a stable approach and touchdown, and provide room for rotor wash and maneuvering. A circle about 100 feet in diameter gives a comfortable safety buffer around the helicopter, so the rotor arcs and tail rotor won’t come close to obstacles in any direction and there’s space to correct any drift during landing or takeoff. Keeping all objects within this zone at no more than 12 inches tall helps ensure debris or protrusions won’t interfere with the rotor system or be kicked up into the aircraft. The other options either underestimate the needed space or don’t specify a practical, safe clearance height, making them less reliable for protecting people and equipment.
