Which statement best describes safe approach to a helicopter when its engine is running?

• A. Approach or depart within the pilot's field of vision to avoid the tail rotor
• B. Approach from the tail rotor side
• C. Approach near the main rotor but stay clear of rotor blades
• D. Approach from above to avoid rotor wash

Answer: (A)

Staying in the pilot’s field of vision while approaching or departing a helicopter with the engine running is the safest rule. When you’re visible to the pilot, he or she can see you and coordinate movements, reducing the risk of a tail-rotor strike and ensuring you’re not stepping into an unsafe part of the rotor system. Approaching from the tail-rotor side is risky because that area is behind the aircraft’s protection zone and the pilot may not see you, making a strike more likely. Moving near the main rotor but still within reach of the blades is still dangerous—blades can move unexpectedly, and you could be pulled into the rotor disk. Approaching from above carries the hazard of rotor wash and losing footing or being hit by the rotor itself. The best practice is to stay where the pilot can clearly see you at all times.
