What diameter in feet is recommended for a relatively level landing area?

• A. 50
• B. 40
• C. 60
• D. 70

Answer: (A)

Safe landing space requires enough clearance around the landing point to absorb movement and keep away from nearby hazards. A 50-foot diameter provides a practical balance: it gives ample room for a relatively level surface to be used without encroaching on surrounding areas, while remaining a feasible size to set up and maintain. If the diameter were smaller, like 40 feet, you’d have less margin for error if the landing isn’t perfectly centered or the ground isn’t perfectly level. Larger diameters such as 60 or 70 feet offer more cushion, but they can be unnecessarily large and harder to secure in many environments, making 50 feet the sensible default.
