What size and condition should the landing zone have for a helicopter medevac?

• A. About 50 by 50 feet.
• B. About 80 by 80 feet.
• C. About 100 by 100 feet, and free of debris.
• D. About 150 by 150 feet.

Answer: (C)

The main idea is that a medevac landing zone must be large enough and clean enough to provide safe clearance for the helicopter’s rotors and for the crew to touch down, maneuver, and depart without obstacles. About 100 by 100 feet gives a generous, standard-sized square that accommodates the rotor sweep and tail rotor clearance while leaving room for a stable touchdown and roll-out. Being free of debris is essential because loose objects can become dangerous projectiles in rotor wash and can damage the rotor, engine intakes, or wheels, as well as injure crew or bystanders. A zone this size and condition also helps ensure you have room for approach and departure paths, reduces the risk of collisions with nearby obstacles, and supports safer operations in varied lighting and weather. Smaller zones leave less margin for error and increase the chance of strikes or tip-overs, while a significantly larger zone is usually not necessary for typical EMS helicopters and could be impractical in many scenes.
