Once the engine start sequence is completed, what role does the starter play?

After the engine start sequence is completed, the starter's role transitions away from initiating engine operation. Instead, it changes to functioning as a 28 VDC generator, which is crucial for supplying electrical power to the aircraft's systems.

Once the engine is successfully started and running, it takes over the role of providing sufficient electrical power, and in this context, the starter is no longer needed for the engine's operation. The generator aspect of the starter ensures that the electrical systems remain powered, which is essential for the functionality of navigational aids, communication systems, and other vital avionics throughout the flight.

The other options do not accurately represent the starter's function after the engine start sequence:

• The notion of the starter acting as a backup to start the engine automatically doesn't apply, as the starter is only engaged during the starting phase and is not designed to activate again without manual intervention.

• While the starter does interface with the accessory gearbox, its role is limited solely to initiating engine operation and does not serve as the main drive once the engine is operational.

• The classification of the starter as a 28 VDC alternator is also incorrect; an alternator specifically converts mechanical energy into electrical energy while typically operating continuously during engine operation, which differs
