Interphone Code 30 indicates which status?

• A. Public Address to main cabin
• B. Interphone call to FD
• C. Cabin ready to FD
• D. FWD Cabin (FA1) interphone

Answer: (C)

Interphone codes are quick signals used by cabin crew to convey the status of interphone communications with the flight deck. Code 30 specifically indicates that the cabin is ready to talk to the flight deck. It means there’s no call in progress and the crew is prepared to establish or receive a conversation with the flight deck through the interphone system. It’s not a live call to the flight deck, nor a public address to passengers, nor a signal for a specific forward cabin interphone.
