Question 13

During single engine operations, how would the pilot correct a fuel imbalance situation?

Answer 13

crossfeed to the low side

Answer 16

When tanks are within 100lbs

Question 17

If the engines burn fuel evenly, what is the most likely way of getting into a fuel imbalance condition?

Answer 17

Running the APU

Question 18

Why do we use the term crossfeed and not crossflow?

Answer 18

Theres no direct crossflow lines. We feed the engines directly from the other tank

Question 19

Is it possible to get the FUEL 1(2) LO LEVEL warning message and not be in a low fuel condition?

Answer 19

Yes.

High pitch angles, scavenger pump failures

Question 20
