What is the recommended "no vehicle movement" restriction distance around a medical helicopter landing zone?

The recommended "no vehicle movement" restriction distance around a medical helicopter landing zone is 300 feet. This guideline is established to ensure the safety of both the helicopter operations and individuals on the ground. The 300-foot buffer allows for a safe clearance zone that minimizes the risk of accidents, ensures the helicopter can land and take off without obstructions, and helps prevent injuries to bystanders or personnel due to rotor wash or the helicopter's downwash.

Additionally, this distance helps in maintaining a controlled environment during critical moments when emergency medical personnel are transferring patients, as this area can often be congested with equipment and personnel engaged in urgent tasks. By adhering to the 300-foot restriction, responders can provide a safer area for the helicopter and the ongoing emergency response activities.
