Answer 5

3-5 minutes

Question 6

The secondary or backup method for refueling the T-6A is called __________ refueling.

Answer 6

over the wing gravity

Question 7

The engine-driven high-pressure fuel pump is fed from the

Answer 7

engine-driven low pressure fuel pump

Question 8

The motive flow line routes fuel to which of the following pumps?

Answer 8

primary jet pump and transfer jet pump

Question 9

The collector tank is equipped with two fuel pumps for engine feed operations. Which one is used after
engine start?

Answer 9

primary jet pump

Question 10

During negative-G flight, the flip-flop valve activates, providing the engine access to fuel located in the

Answer 10

collector tank
