What is the function of a generator in aircraft electrical power?

• A. To store energy.
• B. To regulate voltage only.
• C. To convert electrical energy into mechanical energy.
• D. To convert mechanical energy into electrical energy to power systems and charge the battery.

Answer: (D)

An aircraft generator converts mechanical energy from the engine into electrical energy to power the aircraft’s electrical systems and to charge the battery when the engine is running. It’s driven by the engine (via the accessory drive) and provides the source of electrical power for avionics, lights, actuators, and other loads. It does not store energy—that’s the battery’s role. Regulation is a separate function that keeps the voltage within safe limits, while the generator’s primary job is generation.
