the REFUEL VALVES switches set to NORM
-
the MODE SELECT switch set to REFUEL.
Where the preselected quantity is greater than the maximum capacity of both the wing tanks fuel will automatically be added to the center tank.
The END annunciator, on the preselector 5QT, will come on when the refuel procedure is complete. That is when the ACTUAL value is the same as the PRESELECTED value +/- 100kg (220lb). If the refuel procedure stops before the ACTUAL value and the PRESELECTED value are the same, the END annunciator will flash to show a fault.
To control pressure refuel manually, the MODE SELECT switch on panel (800VU) is set to REFUEL and the REFUEL VALVES switch(es) are set to OPEN. The quantities of fuel that go into the tanks are then monitored at the indicator (6QT). When the tank(s) have the required amounts, the REFUEL VALVE switch(es) are set to SHUT.
