The Main Fuel Control module used on a marine gas turbine engine as shown in the illustration, is responsible for managing which function(s)? Illustration GT-0021

Correct Answer: Option D — all of the above

The Main Fuel Control module acts as the engine's primary governor, integrating multiple inputs to manage fuel flow. It regulates acceleration and deceleration schedules to prevent compressor surge or thermal shock, while simultaneously adjusting variable stator vane positions to optimize airflow and maintain stable combustion throughout the operating range.
