What is the primary function of the main fuel control on the LM2500 GTE?
Official USCG Answer & Rule Citation
Correct Answer: Option C — To control stator vane angle and GG speed
The main fuel control unit regulates fuel flow to the combustors based on power demand. It simultaneously modulates the Variable Stator Vane (VSV) angles to optimize compressor airflow and maintains the gas generator (GG) speed within safe operational limits to prevent surge or over-temperature conditions.
