Aircraft Engine Starter-Generator

Aircraft Engine Starter-Generator is a component of the Engine Electrical System in an aircraft. It falls under the supply class Engine Electrical System Components and belongs to the supply group Engine Accessories.

The Starter-Generator is a combined unit that serves two functions in an aircraft engine. Firstly, it acts as a starter motor to initiate the engine's rotation during the starting process. It provides the initial power required to start the engine and bring it up to the necessary speed for combustion.

Once the engine is running, the Starter-Generator switches to generator mode. In this mode, it generates electrical power to supply various electrical systems and components in the aircraft, such as avionics, lighting, and other electrical devices.

The Starter-Generator is an essential component of the aircraft's electrical system, ensuring the reliable starting of the engine and providing continuous power supply during flight.
