Annunciator) Aviation Parts Catalog

From the aircraft engine providing thrust to the flight control systems allowing for change in direction, there are many very important systems that work together to provide all of an aircraft’s functionalities. The annunciator panel is a group of Lights and Indicators that provide for the status of the various systems within an aircraft, allowing a pilot to be fully aware of aircraft conditions.

Across the different systems, the annunciator part type utilizes different color coded lights to denote the condition or status of a system. Green lights on a system convey that the system is ready to be operated or is in use. White or blue lights mean that the system is in use, and serves as an advisory or indication for seatbelts, anti-ice systems, and landing lights. Amber lights alert the pilot that a system may need attention whether due to an issue of Fuel Control, or the formation of ice. Lastly, red lights are warning signs for the pilot to know that a system needs immediate attention, such as a failure or fire.
