What is the main reason you should avoid entering a helicopter area by going under the body or tail boom?

• A. The pilot may not see you in these areas
• B. These areas are physically blocked by the rotors
• C. The landing gear will move unexpectedly
• D. You must be within the pilots line of sight

Answer: (A)

The main concept is visibility and the cockpit’s blind spots. From the pilot’s seat, views are most complete in front and to the sides, while areas under the fuselage or behind the tail boom are hard for the pilot to see. If you enter that zone, you could be in the rotor or tail-rotor arc without the pilot realizing you’re there, risking a severe injury from moving blades. So the best safety reason is that the pilot may not see you in these areas, making it the safest to stay clear.
