What is the purpose of the annunciation system?

An annunciation system exists to grab the crew’s attention when something abnormal or potentially problematic occurs, so quick action can be taken. It uses visual indicators and audible alarms to signal warnings and cautions, guiding pilots on what needs priority attention and what might require action now. Displaying engine temperatures is done through the cockpit instruments and displays, not the annunciation system. Recording flight data is the job of data recorders, separate from annunciations. And autopilot control is handled by the flight-control system, not by annunciation signaling.
