During a successful GPU start, what should the operational state of the GEN RESET switches be?

• A. In the off position
• B. In the NORM position
• C. In the on position
• D. In the standby position

Answer: (A)

During a successful GPU start, the operational state of the GEN RESET switches should be in the 'off' position. When the generators are in the 'off' position, this prevents any inadvertent loading of the generators during the ground power unit (GPU) start process. This is crucial because it ensures that the aircraft's electrical system is not engaged or drawing power from the generators while the GPU is providing power to the aircraft systems. Keeping the GEN RESET switches off during the initial phases of the GPU start protects the generators and the aircraft's electrical architecture, ensuring a smooth and safe startup process. Once the engines are running and the aircraft systems are stable, the generators can be reset to their normal operational state, allowing them to take over power supply from the GPU.
