definition of annunciator
(also annunciator panel)
a row of lights which give information about the status of how a machine is working or not working. For example on a plane, the annunciator panel gives information about the different subsystems (hydraulics, engine, fuel level etc)
Do not assume that the aircraft is at a waypoint merely because the alert annunciator so indicates. Cross-check by reading present position.
