What is the primary function of the transfer pump in the helicopter?

• A. To expel fuel from the tanks
• B. To move fuel from forward #2 tank to aft #1 tank
• C. To measure fuel pressure
• D. To activate the fuel sensors

Answer: (B)

The primary function of the transfer pump in the helicopter is to move fuel from the forward #2 tank to the aft #1 tank. This operation is crucial for maintaining balanced fuel loads and ensuring optimal weight distribution during flight. By transferring fuel as needed, the helicopter can manage its center of gravity and enhance performance, stability, and handling characteristics.

The other options do not accurately describe the primary role of the transfer pump. Expelling fuel from the tanks pertains to a different system, as does measuring fuel pressure and activating fuel sensors, which are functions related to fuel management and monitoring but do not involve the transfer of fuel between tanks. The transfer pump specifically focuses on the relocation of fuel to maintain balance and operational efficiency within the helicopter's fuel system.
