Flashcards in FUEL Panel Deck (18):

What is the normal in-flight fuel management scheme?

Use center tank first, then the wing tanks


How many fuel pumps are installed (A319/320)?

• 2 in each wing tank
• 2 in center tank
• 1 APU pump to provide fuel to the APU when the tank pumps are off


With full fuel, when do the center tank fuel pumps operate (A319/320)?

• For 2 minutes after BOTH engines are started (if slats are UP will continue to run)
• After slat retraction
• Continue to run for 5 minutes until the center tank is empty or slats are extended


What will cause a FUEL MODE SEL FAULT light?

• Failure of the AUTO mode
• Center tank contains more than 550 lb and either main tank has less than 11,000 lb


What is the approximate fuel capacity of each outer fuel tank (A319/320)?

1521 lbs


When do the main tank outer cells drain into the inner tanks (A319/320)?

When the inner tank quantity reaches 1,650 lbs


If only one inner tank reaches 1,650 lb, what happens to the other transfer valve (A319/320)?

All 4 transfer valves open


Once opened to transfer fuel, how are the fuel transfer valves closed?

Automatically at the next refueling operation


How is the IDG cooled?

By fuel from the HP fuel pump drawn in from the fuel manifold and then returned to it’s respective outer tank.
When full the outer tank spills over to the inner tank


If the IDG return fuel fills the wing tanks, what occurs?

The center tank pumps turn off until the wing tank quantity reduces by approximately 1,100 lb


What does an amber FAULT light in the FUEL PUMP pb indicate?

Low fuel delivery pressure


If the wing tank pumps fail, is gravity feeding possible?

Yes – only from the inner wing tank cells


Can fuel be transferred from one tank to another?

Only during ground refueling


With full wing fuel what prevents the IDG fuel from overflowing the wings?

Separate full level switches


Why are the outer wing tanks drained last?

Structural wing bending moment relief


When does the APU fuel pump run?

When the wing or center tank pumps are not on


What does the REFUEL message on the ECAM indicate?

The refueling control panel door is not closed


What does an amber boxed ECAM FOB indicate?

Some fuel is unusable
