Слайд 2

MENU
During the walk around, you must check several items which are

part of the fuel system.
These items are not major components but a check of their condition is very important.

Слайд 3

MENU
Fuel can be measured manually by the magnetic fuel level indicators

located in each fuel tank.
We are looking at a magnetic fuel level indicator in the right inner tank. It should be flush with the aircraft surface.

Слайд 4

MENU
We are looking at the water drain valve in the right

inner tank. Each tank has a water drain valve.
You should check that there is no water leaking from the valve.
If there is a leak call maintenance.

Слайд 5

MENU
You should check that the REFUEL panel access door is closed.
A

refuel panel is located on the fuselage side beneath the right wing.

Слайд 6

MENU
Note : Another refueling point can be installed under the left

wing as an option.

A single refueling point is installed under the right wing.
You should check that the refuel coupling door is closed.

Слайд 7

MENU
There is one surge tank connected to the outer tank in

each wing tip. These small tanks protect the system against overpressure and thermal expansion.
You cannot monitor or control surge tanks from the cockpit.
The surge tank inlet should be clear of any blockage.

Слайд 8

MENU
There is also a shroud drain mast. It drains fuel that

could leak from the system.
You should check that there is no fuel leaking from the mast.
The items related to the fuel system during the walk around are complete.

Слайд 9

MENU
We will now discuss items related to the fuel system that

you will encounter during cockpit preparation.

To better illustrate what occurs in the fuel system, select the ECAM FUEL page using the ECAM control panel.

MENU
With the pumps in the OFF position, observe the symbology on

the ECAM.
The pumps are cross-line amber.

Слайд 13

MENU
During cockpit preparation, all white ligths in the cockpit must be

extinguished.

Switch ON the left tank pump 1 and observe the ECAM indications.

Слайд 14

During cockpit preparation, all white ligths in the cockpit must be

extinguished.

No. Press the L TK PUMP 1 pb sw.

Слайд 15

extinguished.

No. Press the L TK PUMP 1 pb sw.

Слайд 16

MENU
The left tank pump 1 on the ECAM FUEL page is

in-line green, indicating that the pump is running.

Continue by switching ON the left tank pump 2.

Слайд 19

MENU
The left tank pump 2 is now also running.
Click on the

forward arrow to finish swicthing the center and right tank pumps on.

Слайд 20

MENU
All the pumps are now running.
Click on the forward arrow to

display the E/WD.

Before you continue, you observe a message on the E/WD.

Слайд 21

MENU
The message "REFUELG" displayed on the E/WD indicates that the refuel

control panel door is open.

Now let's continue the preflight by inserting the fuel weight in the MCDU.

Слайд 22

MENU
We have typed the fuel weight in the scratch pad for

you.
Note : You can insert the fuel weight in the MCDU while refueling is in progress.

Enter the Fuel weight in the MCDU .

Слайд 23

We have typed the fuel weight in the scratch pad for

you.
Note : You can insert the fuel weight in the MCDU while refueling is in progress.

No. Press the Line Select Key 2R.

you.
Note : You can insert the fuel weight in the MCDU while refueling is in progress.

No. Press the Line Select Key 2R.

Слайд 25

MENU
Click on the forward arrow to continue.

Слайд 26

MENU
A few minutes later you observe that the refueling message on

the E/WD has disappeared, indicating that refueling is complete and the refueling control panel door is closed.

Слайд 27

MENU
Now that the fuel weight has been entered, let’s verify the

FOB.
Note : the minimum fuel quantity for take-off is 1500 kg.

Слайд 28

MENU
Verify that the Fuel On Board quantity on the E/WD and

on the ECAM FUEL page corresponds to the fuel required by the computerized flight-plan.

Слайд 29

MENU
Verify also the fuel distribution in the different tanks.

Слайд 30

Слайд 31

MENU
and the fuel line dowstream from the low pressure valve is

amber indicating the APU is not running.

It’s now time to start the APU.
Before we start it, notice that :
the APU low pressure valve is closed (cross-line green),

Слайд 32

MENU
We have started the APU for you.
On the ECAM FUEL page

you can see that the APU is running because :
the APU Low Pressure valve has opened (in- line green),

and the fuel line dowstream is green.

Слайд 33

MENU
The items related to the fuel system during cockpit preparation are

complete.

We will now discuss items related to the fuel system that you will encounter during engine start.
The indications and starting procedures are the same for both engines.
In our example we will start engine 2 first.

Слайд 34

MENU
Normally, during engine start, the ECAM ENGINE page will be automatically

displayed.
For training purposes only, to better illustrate what occurs in the fuel system, the ECAM FUEL page will be presented.

Select the ECAM FUEL page on the ECAM control panel.

Слайд 35

No. Press the FUEL key.
Normally, during engine start, the ECAM ENGINE

page will be automatically displayed.
For training purposes only, to better illustrate what occurs in the fuel system, the ECAM FUEL page will be presented.

Слайд 36

MENU
The Gross Weight (GW) has now appeared . This indication is

not available until after the second engine is started.

Слайд 52

MENU
Observe the message CTR TK FEEDG has appeared on the ECAM

E/WD. This indicates that the center tank pumps are feeding the engines.

Слайд 53

MENU
The items related to the engine start are complete.
We will now

discuss items related to the fuel system that you will encounter during taxi.

Слайд 54

MENU
Extend the slats, and observe the indications.
When we extend the slats,

you will see one of the automatic functions of the center tank pumps.

Notice that the MODE SEL pb sw is set to AUTO.

Слайд 55

No. Click on the FLAPS lever.
When we extend the slats, you

will see one of the automatic functions of the center tank pumps.

Notice that the MODE SEL pb sw is set to AUTO.

Слайд 60

MENU
The items related to TAXI are complete.
We will now discuss items

related to the fuel system that you will encounter during normal climb, cruise and descent.

Слайд 62

MENU
You are in climb, the slats are now retracted.
Observe the CTR

TK FEEDG message reappears. This indicates (at slats retraction) the center tank pumps are again feeding the engines.

Select the ECAM FUEL page on the ECP.

This is another automatic function of the center tank pumps with the MODE SEL pb in AUTO .

Слайд 63

You are in climb, the slats are now retracted.
Observe the CTR

TK FEEDG message reappears. This indicates (at slats retraction) the center tank pumps are again feeding the engines.

No. Press the FUEL key.

This is another automatic function of the center tank pumps with the MODE SEL pb in AUTO .

Слайд 64

You are in climb, the slats are now retracted.
Observe the CTR

TK FEEDG message reappears. This indicates (at slats retraction) the center tank pumps are again feeding the engines.

No. Press the FUEL key.

This is another automatic function of the center tank pumps with the MODE SEL pb in AUTO .

Слайд 65

Observe the corresponding pump indications on the ECAM (in-line green).
MENU

Слайд 66

MENU
You are now in cruise.
Notice the CTR TK FEEDG message has

again disappeared indicating that the center tank pumps have automatically shut off. However the center tank is not empty and an AUTO function has again occurred.
To explain why, we must look at fuel recirculation.

Слайд 67

Слайд 68

MENU
Some fuel to the engines is diverted to cool the Integrated

Drive Generators (IDGs) then returns to the wing tanks.
If the engines are fed from the center tank and the wing tanks are full, the center tank pumps automatically shut off.
The inner tank pumps take over and feed the engines so that there is room for fuel from the IDGs.

Слайд 69

After the inner tank pumps have fed approximately 500 kg of

fuel, the center tank pumps automatically restart.

Слайд 70

You are in descent.
To better illustrate the remaining indications, we will

keep the ECAM FUEL page displayed.
The center tank pumps have automatically shut off (cross- line green) because the center tank is empty.
The inner tanks are now again feeding the engines.
Let’s see what happens when the inner tanks reach a low level.
