What is the primary function of the main fuel control on the LM2500 GTE?

Correct Answer: Option B — To control stator vane angle and GG speed

The main fuel control regulates the fuel flow to the combustors while simultaneously modulating the variable stator vane angles and gas generator speed. This integrated control logic ensures optimal engine performance, preventing compressor stalls and maintaining stable operation across the entire power range of the LM2500 engine.
