3 Pressure refuelling system description and common component locations.

General

Fuel is contained in three integral fuel tanks, one in each wing and one in the fuselage centre section. Arefuel/defuel station, situated in the underside of the right wing leading edge, consists of a standard fuelcoupling, an off-load valve for defuelling and transfer between tanks, and a refuel control panel.

Aircraft fuel tank capacities

Imp gal US gal litre lb kg

Wing left 1015 1219 4614 8120 3683

Centre 550 661 2500 4400 1996

Wingright 1015 1219 4614 8120 3683

Total 2580 3099 11,728 20,640 9362

These quantities refer to an aircraft fuelled to override cut-off. When gravity filled, the quantity in each wing tank reduces to 1005Imp gal. (1207 US gal., 4569 litre, 8040 lb., 3647 kg.) but the centre tank quantity remains the same.

The automatic refuel preselect will only refuel TNT Aircraft to a to tal of 8800kg. (3500 kg / 1800 kg / 3500 kg)If a higher fuel load is required then the refuel must be continued after shutdown of the automatic system by selecting the refuelvalve switches to override

WARNING: If a “ Full tanks” refuel is started with the refuel switches set directly to override there isa high risk of a fuel spillage from the NACA ducts at the wing tips due to venting.

Refuelling – Overview

1 Pressure refuelling is governed from the control panel; automatically by using theload preselect, or manually by use of the tank refuelling valve override switches.

2 In the event of refuel cut-off failure the system is vented to atmosphere

via a NACA duct located in each wing tip.

3 Over wing gravity refuelling

In the event of the pressure refuel system failing it is possible to refuel the aircraft using the over wing gravityrefuelling points.

Over wing gravity refuelling points are provided for each tank for refuelling when the pressure system fails.

Performing Pressure refuelling

1 Pre refuel system test

2 Perform a water test before fuel is uploaded to the aircraft

3 Perform the pressure refuel

15 of 25



1 Perform a pre-refuel system test

1 At refuel control panel, make certain off-load valve is shut (lever horizontal), and MASTERswitch is set to OFF, left, centre and right refuel VALVE position indicators show cross-hatch.

2 Turn LOAD PRESELECT clockwise to maximum.

3 Set MASTER switch to ON. Make certain refuel VALVE position indicators go to SHUT, and fuelquantity indicators show correct existing fuel state.

4 Set LEFT, CENTRE and RIGHT refuel valve switches to PRE-SELECT and make certain allthree refuel VALVE position indicators go to OPEN.

5 Turn LOAD PRESELECT ANTI-clockwise to zero and make certain all three refuel VALVEposition indicators go to SHUT.

NOTE: If the tank contents are at or below unusable fuel level (the level at which the gaugesand preselect are set at zero) then the valves will not shut.

6 Set all refuel valve switches to OVERRIDE and make certain all three refuel VALVE positionindicators go to OPEN.

7 Set switches to SHUT and make certain refuel VALVE indicators go to SHUT.

2 Perform a water test on a sample of fuel taken from thevehicle test point before any fuel is uplifted to the aircraft.

A sample of fuel is to be taken from the vehicle water test point and a standard industrytest is to be performed to ensure the fuel is free from water.

The test sample should be retained for inspection by flight crew / TNT representative ifrequested.

The test sample may be disposed of after departure of the aircraft

2 Position tanker hose coupling and bond hose to aircraft. Remove blanking cap fromaircraft fuel coupling and connect tanker hose.

3 Set all three refuel valve switches to PRE-SELECT and adjust LOAD PRESELECT torequired load.

a) - Switches to preselect

Down SHUTMid PRESELECTUp OVERRIDE

b) - Then adjust load preselect

4 Make certain refuel VALVE position indicators show OPEN for all tanks due to receivefuel.

NOTE: If load selected does not require fuel in the centre tank, the CENTRE indicator will showSHUT.

21 of 25



5 Start refuelling. Flow will stop automatically at preselected load.

6 For absolute maximum fuel load, set refuel valve switches to PRE-SELECT and adjustLOAD PRESELECT to its maximum,

a. Continue refuelling to preselect cut-off.

b. Then set refuel valve switches to override, make certain refuel valve indicators showOPEN, continue refuelling until high level tank switches operate and fuel flow stops.Make certain tank FULL indicators come on.

NOTE: The automatic refuel preselect wil l only refuel TNT Aircraft to a total of 8800kg.(3500 / 1800 / 3500)

If a higher fuel load is require then the refuel must be continued after shutdownof the automatic system by selecting the refuel valve switches to override

WARNINGIf a “ full tanks” refuel is started with the refuel switches selected directly to theoverride position there is a high risk of a fuel spillage from the NACA ducts atthe wing tips due to venting.

22 of 25



7 Make certain all refuel VALVE indicators show SHUT, and fuel quantity indicators showrequired fuel load.

8 On refuel panel make certain fuel quantity indicators show correct fuel load.

9 At refuel control panel, set refuel valve switches to SHUT, and MASTER switch to OFF.

10 Disconnect tanker hose bonding and uncouple hose from aircraft.

11 Install blanking cap to aircraft fuel coupling.

12 Close and secure refuel/defuel station access panel

(If the panel is not locked securely by all 3 latches the aircraft battery candischarge)

13 Disconnect tanker bonding from aircraft.
