Which signal is shown by placing arms by side, palms forward, with arms swept forward and upward repeatedly to shoulder height?

• A. Release sling load
• B. Takeoff
• C. Move backward
• D. Move to left

Answer: (C)

In sling load signaling, the motion described uses a neutral start with arms by the sides and palms facing forward, then repeatedly sweeping the arms forward and upward to shoulder height. That specific pattern is the standard sign for moving the load backward. The repeated forward-and-up sweep communicates to the operator to back the load away from you, creating clearance or repositioning space.

This signal is distinct from other gestures that indicate left or right movement, takeoff, or releasing the load, which use different directions or motions. So the described arm sequence best matches the backward movement signal.
