"Good To Know" Limitations Flashcards

1
Q

What is an important consideration regarding thrust reverser operation during takeoff and landing?

A

Take off and landing are not authorized if either thrust reverser is inoperative AND the runway is contaminated, OR braking action less than good.

Q

What is the minimum onboard fuel for ground operation of the electric hydraulic pumps?

A

1675 pounds in the respective wing tank. This is because the fuel heat exchanger for the hydraulic pumps is inside of the fuel tank.
