Engine Gas Turbines (Supplementary) USCG Question #103 (Set 4)

What is the purpose of the LM2500 GTE enclosure heater?

Official USCG Answer & Rule Citation

Correct Answer: Option C — To ensure fuel viscosity is maintained while the GTE is secured

The LM2500 enclosure heater maintains the ambient temperature within the module during standby periods. This prevents fuel from cooling below its cloud point, ensuring that fuel viscosity remains within the manufacturer's specifications for immediate restart and preventing wax formation that could clog fuel filters or injectors during cold starts.
