Answer 22

Engine start
Cross feed
Main jet pump failure

Question 23

What indicates a loss of motive flow

Answer 23

Buy electric boost pumps cycling On and OFF in AUTO with LOW PRESS light ON

Question 24

How is fuel quantity measured

Answer 24

Quantity transmitters send signals to the master quantity indicators. This system is capacitate type system
Fuel can also be measured by magnetic dripless measuring stick
