When approaching a helicopter carrying a patient, who authorizes the approach and from which direction if directed?

• A. The lead EMT may approach from any side after establishing scene safety.
• B. The landing zone supervisor signals from the ground only.
• C. Approach only with pilot or crew permission, usually from the front if directed.
• D. Approach from the rear to avoid rotor wash if clearance is given.

Answer: (C)

In helicopter EMS, you must get explicit permission from the flight crew before stepping toward the aircraft. The pilot or onboard crew controls when it’s safe to approach and where you should enter.

If you’re directed to approach, do so from the front. The front position keeps you in the pilot’s line of sight, makes communication clear, and reduces the risk of hitting the tail rotor or getting caught in rotor wash from the rear. The crew can guide you along the safest path and timing.

Rotor hazards and ground crew coordination are the main reasons for this. Approaching without crew authorization can lead to dangerous encounters with spinning blades, unexpected rotor wash, or debris being blown around. The other options don’t provide the same safety control—the pilot or crew has the overall authority and visibility to manage the approach, and a rear approach increases risk due to the tail rotor and blind spots.
