Which gesture should be used to signal a helicopter for rescue?

• A. Stand with arms at sides
• B. Clap twice
• C. Spin in circles
• D. Wave one arm overhead

Answer: (D)

To be seen by a helicopter, use a simple, highly visible hand signal that aircrew can spot from above. Waving one arm overhead creates a tall, clear motion against the sky and water, making it easy for the helicopter crew to recognize you as needing assistance. It’s a standard distress signal for aerial rescues, so they can locate you quickly and respond. The other gestures aren’t effective signals from above: standing with arms at your sides is hard to notice, clapping is noisy but not visually identifiable from the air, and spinning in circles can be mistaken or missed. After signaling, stay in a safe, visible area and follow the crew’s instructions once they arrive, avoiding the rotor wash.
