If the interphone fails, how should you coordinate with other crew members?

• A. Use hand signals, predefined rendezvous points, and backup signaling methods to convey instructions
• B. Speak directly to a specific crew member via a personal radio device
• C. Communicate only through written notes
• D. Wait for orders from the captain

Answer: (A)

When the interphone isn’t working, you rely on pre-established, nonverbal procedures to stay coordinated. Using hand signals lets crew convey quick, silent instructions without sound, which is crucial in a busy cabin or galley where vocal communication can be noisy or distracting. Predefined rendezvous points ensure everyone knows exactly where to meet to share information, assess the situation, and assign tasks without needing to talk over the interphone. Backup signaling methods — such as visual cues or brief, concise written notes — provide additional ways to pass essential information without relying on electronic systems.

This approach is the most reliable under interphone failure because it uses simple, universally understood signals and a clear plan for gathering and communicating. Relying on a personal radio device assumes the device is functioning and part of the same plan, which may not be guaranteed when the interphone is down. Communicating only through written notes is too slow in urgent situations, and waiting for orders from the captain can delay critical actions.
