What is the function of the jet pumps in the fuel system?

The function of jet pumps in the fuel system is primarily to transfer fuel from the wing, rear, and forward tanks to the feeder tanks. This process is crucial because it ensures that the feeder tanks, which supply fuel to the engines, are consistently maintained at the appropriate level for optimal engine operation. By using the jet pump's capabilities, the system can efficiently manage fuel distribution and ensure that the engines have uninterrupted access to fuel, even in scenarios such as turbulence or changes in aircraft attitude.

Jet pumps achieve this by using the Bernoulli principle, which allows them to create a low-pressure area that helps move fuel from one location to another without the need for additional mechanical pumps. This capability is essential for maintaining balance and performance in the aircraft’s fuel system.

Other options may address aspects of fuel management but do not specifically describe the primary role of jet pumps accurately, making them less relevant in this context.
