To cool the IDG oil
9
How can you check that fuel quantity (FQI) is in degraded mode?
FQ indication is dashed amber across the two last digits on the upper ECAM and ECAM fuel page must be called to check which tank is affected

How many pumps are there in each fuel tank?
Two fuel pumps in each wing tank
13
If open, when will the transfer valves close again?
Transfer valves close automatically at the next refueling operation
14
In case of single engine operation:
Cross feed valve must be kept open
15
In normal operation the cross feed valve is:
Closed for the take off
16
In normal operation, each engine is supplied by:
Two wing tank pumps and one center tank pump
17
Is the gravity feeding from center tank possible:
No
18
On the crossfeed pb, what is the meaning of the "ON" white light?
The valve opens
19
Suction valves are:
Normally closed by pumps pressure
20
The LP valves are controlled to off position by:
Engine master switches and fire pushbuttons
21
The engine low pressure (LP) valve is closed by:

1,500 kg
24
The maximum refueling pressure is:
50 psi (3.5 bars)
