During normal operation with the bus tie closed, which electrical buses are powered by the generator?

The generator is responsible for providing power to both the generator bus and the battery bus during normal operation when the bus tie is closed. This configuration allows for optimized power distribution and ensures that the electrical systems of the aircraft remain operational.

In this scenario, when the bus tie is closed, it facilitates the connection between the generator bus and the battery bus, allowing for a dual-source supply of electricity. The generator bus receives power directly from the generator, while the battery bus is also energized to maintain consistent voltage levels and capacity for starting or supporting systems if needed.

By powering both buses, the system can effectively manage the electrical load across various components in the aircraft, enhancing reliability and safety during operations. Therefore, the correct answer encompasses both the generator and battery buses, demonstrating the comprehensive role of the generator in maintaining electrical operations.
