Which signal indicates Move backward?

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

Answer: (B)

In sling-load signaling, ground crew use standardized hand signals with clear meanings to guide the helicopter crew. Each signal is a distinct command, so the pilot can respond quickly and safely to reposition, lift, or detach the load.

The signal that tells the helicopter to back away is the one whose meaning is Move backward. That is exactly the action needed when you want the helicopter to reverse its motion relative to the load or position, such as pulling back to create clearance or reorient for the next move. The other options correspond to different actions: Move upward means raise the load, Release sling load means detach the load, and Move to left means shift laterally. So the Move backward signal is the one that communicates backing up.
