Which generator operates the start motor?

The correct answer is that Generator 2 operates the start motor in the Pilatus PC-12 NG. This is significant because Generator 2 is specifically dedicated to providing electrical power to essential systems, particularly during engine start.

When the aircraft is in the process of starting, it requires substantial electrical power that Generator 2 is designed to deliver effectively. It ensures that the start motor receives the necessary voltage and current required for starting the engine, thereby enhancing reliability during this critical phase of operation. Generator 1, on the other hand, supports other systems once the engine is running, but does not supply the start motor. Understanding which generator is responsible for engine start helps pilots and maintenance personnel ensure proper operation and troubleshooting of the electrical system during various phases of flight operation.
