During an auto-start sequence on the marine gas turbine control console shown in the illustration, what would be the correct order of events required to occur after the start sequence begins? Illustration GT-0016

Correct Answer: Option B — NGG reaches ignition RPM, gas temperature greater than 400 degrees F, NGG reaches idle RPM

Automated starting sequences require the gas generator (NGG) to reach ignition speed to ensure sufficient airflow. Once ignition is confirmed by a temperature rise above 400 degrees F, the controller continues the acceleration ramp until the NGG reaches stable idle RPM, ensuring safe transition to self-sustaining operation.
