If the interphone system is inoperative, which communication methods can crew use to communicate with passengers?

• A. Public address system if available, visual signals, and standardized hand signals.
• B. Public address announcements only.
• C. Shouting and hand claps to attract attention.
• D. Wait until ground crew arrives to communicate.

Answer: (A)

When the interphone is inoperative, you still need clear, immediate ways to reach all passengers. Use the public address system if it’s still available to deliver concise instructions to the cabin. Pair that with visual signals to capture attention and reinforce the message, such as turning on cabin lights or making deliberate, observable gestures. Standardized hand signals are essential too, because they convey specific commands quickly and can be understood by everyone, regardless of language or hearing ability. This mix provides redundancy and clarity, ensuring passengers receive and understand safety instructions promptly. Shouting or clapping can create confusion or panic and isn’t a reliable method, and waiting for ground crew would delay critical information.
