Which component is responsible for augmenting fuel flow to the engine during high demand?

• A. Free wheeling unit
• B. Fuel control unit
• C. Fuel boost pumps
• D. Engine driven fuel pump

Answer: (C)

The fuel boost pumps are critical components that enhance fuel flow to the engine during periods of high demand, such as during takeoff, heavy acceleration, or rapid throttle inputs. Their primary function is to ensure an adequate supply of fuel is delivered to the engine, particularly under conditions where the demand for fuel exceeds what can be provided by gravity feed or other systems alone. The fuel boost pumps work by increasing the pressure of the fuel, ensuring consistent flow and preventing vapor lock under extreme operating conditions. This is particularly important in maintaining engine performance and preventing potential failures or stalls caused by insufficient fuel pressure. While the engine-driven fuel pump and fuel control unit play significant roles in the overall fuel delivery system, they do not specifically augment fuel flow during high demand conditions as effectively as the fuel boost pumps do. The free wheeling unit is unrelated to fuel delivery, focusing instead on rotor function and maintaining operational efficiency in different flight regimes. Thus, the fuel boost pumps are essential for ensuring that the engine receives the fuel needed during critical moments, making them the correct answer to the question.
