Question 17

Fuel system?

Answer 17

Outers 678kg
Inners 5 396kg
Centre 6 474kg
Total 18 623kg

-Fuel supplied fuel from inner tanks to engines- 4 pumps.
-2 electrical transfer valves permit transfer from outer to inner.
- suction valves allow gravity feeding if inner tank pumps fail (closed by pump pressure in normal operation).

Question 19

Fuel feed sequence?

Answer 19

Tanks empty in the following sequence :
1. ACT2 transfers into center.
2. ACT1 transfers into center.
3. Center transfers into inners.
4. Each inner empties down to 750 kg.
5. Outer transfers into inners.

Question 20

When does centre tank transfer valve open?

Answer 20

500kg of inner used.

MODE SEL in MAN position- Inner tank overflow must be prevented by selecting the CTR TK XFR pb-sw OFF when the inner tanks are
full. They must also be selected OFF when the center tank is empty.

Question 21

When does fuel transfer from outer to inner tanks?

Answer 21

When inner reaches 750 kg.
Valves are then latched open- automatically close at next refueling.

Question 22

Warmup?

Answer 22

After start to avoid thermal shock, operate ENG
at IDLE for 3min
