The guidelines such as approaching in view of the pilot, not approaching with items tall enough to contact rotor blades, never approaching a single-rotor helicopter from the rear, and not moving from one side to the other by going around the tail are applicable when which scenario arises?

The guidelines such as approaching in view of the pilot, not approaching with items tall enough to contact rotor blades, never approaching a single-rotor helicopter from the rear, and not moving from one side to the other by going around the tail are applicable when which scenario arises?

• A. When approaching a running helicopter
• B. When performing maintenance on a parked bus
• C. When fueling an airplane on the ramp
• D. When walking near a stationary wind turbine

Answer: (A)

Approaching a helicopter when its rotor is turning requires careful attention to rotor hazards and pilot visibility. When the rotor is moving, the danger zone around the blades is large and can reach well beyond the rotor hub, so you should always present yourself to the pilot in their line of sight. This helps the pilot see you and communicate any instructions or warnings. Keep any personnel or equipment well clear of the rotor arc, and avoid carrying items tall enough to contact a blade. The tail rotor is especially dangerous because it can be obscured from view; never approach a single-rotor helicopter from the rear where you could be hit by the tail rotor, and do not cross from one side to the other by going around the tail, which would place you directly in the tail-rotor plane. These precautions are specific to helicopters in operation. Other scenarios involving buses, airplanes on the ramp, or wind turbines do not involve the same rotor hazards or the need to stay in the pilot’s line of sight.
