Which hand and arm signal is demonstrated by left arm extended forward horizontally, fist clenched, right hand making a horizontal slicing movement below the left fist, palm downward?

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

Answer: (B)

In sling-load signaling, the left arm position serves as a reference point, while the right hand performs a motion that communicates the specific action. The described posture—left arm extended forward with a clenched fist and the right hand making a horizontal slicing movement below the left fist with the palm facing downward—matches the standard signal for releasing the sling load. The horizontal slice acts as a clear “cut” moment, and the palm-down orientation reinforces letting go downward, which is exactly what the crew needs to do when instructed to release the load.

The other options don’t fit this motion pattern. Signals for moving backward, taking off, or moving upward use different arm positions or motions, not the horizontal slicing gesture described here.
