When you hear a sharp blast whistle you?

• A. Proceed with work
• B. Ignore the whistle
• C. Throw Chocks / Stop All Movement
• D. Wave to signal

Answer: (C)

A sharp blast on the whistle is a stop-all-movement command on the flight deck. When you hear it, you must halt any active movement and secure the aircraft by throwing chocks to prevent rolling. This signal is used to rapidly create a safe halt during high-risk deck operations, protecting crew and aircraft from collisions or unintended motion. Continuing work or ignoring the signal would be dangerous, and waving to signal isn’t an approved method to stop movement on the deck.
