What is the appropriate response when the captain calls with four high/low chimes?

• A. Acknowledge with your name only
• B. Speak to the captain and ignore the instruction
• C. Reply with 'Roger' and proceed
• D. Identify yourself, location, TNT, and repeat what the captain tells you for clarification

Answer: (D)

Clear bridge-to-bridge communication hinges on identification and verification. When the captain signals with four chimes, you must respond in a way that makes exactly who you are, where you are, and what was said unmistakable, so there’s no misinterpretation under noise or stress. The best response is to identify yourself, give your location, state the vessel’s call sign (TNT), and then repeat the captain’s instruction for clarification. This creates a precise record in both parties’ minds of what will be done and avoids half-understood commands or assumptions. Acknowledging with just your name lacks location and mission context. Saying “Roger” confirms receipt but not understanding or intent, which can be risky if the instruction is misheard. Simply engaging with the captain or ignoring the directive can lead to unsafe actions. Repeating the captain’s instruction ensures you heard it correctly and signals you are ready to act as directed. This approach keeps everyone on the same page and supports safe, orderly operations.
