Outer tanks, fuel transfers to inner.

Question 9

The fuel transfer valves open when the inner tank fuel quantity reaches —-kg

Answer 9

750kg, thus allowing the fuel to drain from the outer to the inner tanks. The valves remain latched open and will automatically close at the next refuelling.

Question 10

The ——— controls the fuel return valve

Answer 10

FADEC

Question 11

The fuel return valve directs the returning fuel (post IDG cooling) into the:

Answer 11

Outer tank. If the outer tank is already full the fuel overflows to the inner tank via a spill pipe. If centre tank is feeding the system the wing tank will tend to over fill and the system automatically selects the centre tank pump off when the inner tank is full. The wing tank pumps will feed until the level drops by 500kg

Question 12

The Low Level ECAM Warning will be generated when the wing tank quantity goes below ____kg. This warning is generated independently from the fuel quantity indication of the tank.

Answer 12

750

Answer 13

5 minutes

Question 14

Two dashes appear across the last 2 digits if the fuel quantity indicator when:

Answer 14

The FQI is inaccurate

Question 15

The FOB quantity indicator is boxed amber when either:

Answer 15

Answer 16

250kg

Question 17

Maximum A320 contingency fuel is:

Answer 17

20 minutes of trip fuel

Question 18

Answer 19

Low level (750 kg)

Question 20
