What are the two primary sources of electrical power in an aircraft?

The two primary sources of electrical power in an aircraft are the generator and the battery. The generator, usually part of the aircraft's engine system, provides electrical power during flight, ensuring that vital systems remain operational. It converts mechanical energy from the aircraft's engine into electrical energy, supplying power to various systems such as navigation, lighting, and communications.

The battery serves as a secondary power source, particularly during engine start and in the event of generator failure. It stores electrical energy and is crucial for starting the aircraft's systems when the engine is off or when other power sources may be unavailable. Additionally, the battery provides backup power during critical situations, ensuring that essential functions can continue to operate.

In summary, the generator and battery work together to supply the necessary electrical power to keep an aircraft functional in various scenarios, making them the primary sources of electrical power in aviation.
