In flight, which component provides electrical power?

• A. Generator
• B. Battery
• C. Alternator
• D. Power inverter

Answer: (A)

Electrical power in flight is supplied by the generator, driven by the engine. As the engine turns the generator, it converts mechanical energy into electrical energy to power the aircraft’s electrical system, keeping instruments, avionics, and lights running continuously while airborne. The battery sits on board to help start the engine and to provide limited backup power if the generator isn’t supplying power, but it isn’t meant to run the entire system for extended flight. The inverter’s role is to change DC power to AC for specific equipment when needed, not to be the primary source of power. In many aircraft, the same device may be referred to as a generator or an alternator, but the essential concept is that it’s the engine-driven source that provides electrical power during flight.
