What is the primary function of the Annunciator Panel?

• 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: (B)

The Annunciator Panel is the visual alert center that signals status and alerts to the flight crew. It’s a bank of colored lights that light up in conjunction with the aircraft call chime system, so when a passenger or crew member presses a call button, the corresponding light illuminates and a chime may sound. The color coding helps quickly identify what type of alert it is and how urgent it is—red for urgent warnings, amber for cautions, and other colors for specific calls or system statuses. This setup lets the crew know exactly where attention is needed and respond promptly, which is essential for safety. It isn’t used for showing seat numbers, controlling weather radar, or managing passenger announcements, which are handled by other systems.
