What roles do call buttons and interphones play in emergencies?

• A. They enable rapid coordination between passengers, cabin crew, and cockpit.
• B. They are used only for requesting meal service.
• C. They are decorative and have no function.
• D. They can only be used by flight attendants.

Answer: (C)

In emergencies, fast, clear communication across everyone on board is essential. Call buttons and the interphone provide direct, priority channels that connect passengers, cabin crew, and the flight deck, allowing someone to summon help, relay vital information, and coordinate actions quickly. This enables timely medical assistance, alerts to the pilots about developing issues, and organized evacuations or safety procedures. They are not just for meal service, not decorative, and not restricted to flight attendants; any passenger or crew member can use these systems to convey urgent information, which is why rapid coordination between passengers, crew, and cockpit is how their role is best understood.
