What is the recommended area size for a helicopter landing zone (LZ)?

The recommended area size for a helicopter landing zone (LZ) is 100x100 feet on firm and level ground. This size is optimal for ensuring the safety of both the helicopter and the personnel involved in landing and takeoff operations. A space of this dimension provides sufficient clearance for the rotor wash and the aircraft itself while allowing enough room for emergency personnel to maneuver safely during landing and loading procedures.

Choosing firm and level ground is critical, as it enhances stability during landing and takeoff, which is essential for the safety of the helicopter and its occupants. Inadequate space can lead to dangerous situations, especially in emergency scenarios where precision and the ability to react quickly are paramount. This standard ensures that emergency medical services can operate efficiently while maintaining the highest safety protocols.
