Interphone code 22 is used to contact which cabin?

• A. FWD Cabin (FA1)
• B. AFT Cabin (FA2)
• C. Public Address (PA) to main cabin
• D. Emergency call to all stations

Answer: (A)

Interphone codes map to specific cabin areas in the crew communication system. Code 22 is preassigned to contact the forward cabin, FA1. Entering 22 sends a direct call to the forward cabin FA1, so that particular station can respond quickly and privately. The Public Address to main cabin uses the PA system rather than this interphone code, so it isn’t reached by 22. An emergency call to all stations would trigger a different, system-wide alert that goes to every station, not just the forward cabin. The aft cabin would have its own distinct code, not 22.
