INTERPHONE is the device used to speak to the flight deck.

• A. The public address system
• B. The device used to speak to the flight deck
• C. The cabin intercom system
• D. The onboard intercom for cabin crew only

Answer: (B)

Interphone refers to the private communication link that cabin crew use to contact the flight deck. It’s the dedicated device for talking with the pilots, separate from systems meant for passengers or for cabin-to-cabin talk. The public address system is what you use to reach passengers, not pilots. The cabin intercom and the cabin crew-only intercom describe internal crew communication within the cabin, not the specific link to the flight deck. So the description that matches exactly—“the device used to speak to the flight deck”—is Interphone.
