The fuel system for the Gas Turbine Engine (GTE) receives its fuel from the ship supply and enters the boost section of which fuel pump?

• A. Engine-driven fuel pump
• B. Main fuel pump in the tank
• C. Accessory-Drive Gearbox (AGB) driven fuel pump
• D. External boost pump

Answer: (C)

The system uses a boost stage to raise the ship-supplied fuel to the pressure needed by the engine’s fuel control and injectors. That boost section is inside the pump driven by the Accessory-Drive Gearbox (AGB). The AGB drives the fuel pump so it can deliver the higher pressure required during starting and low RPM, ensuring the engine never starves for fuel. The other pumps described are not the ones that house the boost section feeding the engine; the main in-tank pump or an engine-driven pump provide different parts of the fuel supply, and an external boost pump is a separate priming device rather than the boost section used during normal operation.
