Which actions help ground personnel prevent injuries from rotor downwash during loading and unloading?

• A. Rely on pilot cues and proceed with loading without a defined staging area.
• B. Stand clear of rotor arcs but do not use ground guides.
• C. Maintain safe distances, follow ground guides, use defined staging areas, brief all personnel on rotor arcs, and secure loads before movement.
• D. Only the load handler needs PPE; others are exempt.

Answer: (C)

Preventing injuries from rotor downwash in loading and unloading comes from creating a safe, controlled operating envelope around the helicopter. Keep everyone at safe distances and out of the rotor arcs, and use ground guides to direct people and vehicles so movement is predictable. Establish a defined staging area to prevent crowding and accidental entry into the rotor zone, and brief all personnel on where the rotor arcs are and what the planned movements will be. It’s also essential to secure loads before any movement so nothing shifts or becomes projectiles in the downwash.

These elements work together because downwash can push people and objects unexpectedly, and rotor arcs can sweep suddenly. A planned, communicative setup with guides and staging reduces surprises and keeps the team out of danger. Relying on pilot cues alone isn’t reliable, as cues can be missed or misinterpreted; standing clear without guides lacks controlled direction; and PPE alone doesn’t address the broader risks from downwash and moving loads.
