Annunciator Panel is described as?

• A. Panel showing seat numbers
• B. Bank of colored lights that work in conjunction with the aircraft call chime system
• C. Panel for weather radar
• D. Panel controlling passenger announcements

Answer: (A)

The main idea is that an annunciator panel is a bank of indicator lights that work with the aircraft’s call chime system to provide visual alerts for calls and other cabin status. When a passenger presses a call button, or a lavatory or crew call is activated, the corresponding light on this panel illuminates to show where attention is needed. This gives flight attendants immediate, location-specific awareness without needing to hear or read a separate message. It isn’t a display of seat numbers, it isn’t the weather radar panel, and it isn’t the panel used to control passenger announcements. The lights together with the call chime system are what define an annunciator panel.
