What is the primary function of the TH-73A fuel transfer pump?

• A. To move fuel from No.1 Cell to No.2 Cell
• B. To circulate fuel within the same cell
• C. To move fuel between portions of different cells
• D. To filter fuel before engine entry

Answer: (C)

The primary function of the TH-73A fuel transfer pump is to move fuel between portions of different cells. This capability is essential in maintaining balanced fuel loads among the fuel cells. By transferring fuel, the pump ensures that the aircraft can maintain its center of gravity and optimize performance throughout the flight. Each fuel cell has a specific capacity, and during the operation of the aircraft, it's crucial to manage the fuel levels to prevent any imbalances that could affect stability and control. The transfer pump helps redistribute fuel as necessary, ensuring that each cell is adequately utilized and that the fuel system operates efficiently. This function is distinct from simply moving fuel from one cell to another or circulating it within the same cell, which may not actively manage fuel distribution or balance. Additionally, filtering fuel before it enters the engine is a different function that is typically handled by fuel filters, not the transfer pump itself.
