1.7.5. External fuel transfer switch
The two-position switch located under the fuel quantity selection knob is used to invert the way the
external tanks feed into the internal wing tanks. Obviously it is used only when both external wing and
centreline tanks are carried.
Normally the centreline tank empties first into both the internal wing tanks. It is therefore the first tank
that is emptied. This is what happens when the switch is the NORM position.
But in some cases the mission may dictate that the wing tanks are emptied first so they can be
jettisoned (think CAT I). In this case the switch would be placed to the WING FIRST position so the
external wing tanks empty first into the internal wing tanks and can be jettisoned. The centreline tank
would then start to empty into the internal wing tanks.
1.7.6. Fuel checks
Keeping a close eye on your fuel system is paramount to mission success. Flight Leads will often
request fuel state or an Ops check to ensure that no one in their flight runs out of fuel or has an
imbalance problem. But you are the pilot and your fuel is your responsibility, so
don’t wait for your
Flight Lead to check it for you. Check it as often as possible and not only the fuel gauge, but also the
fuel remaining at different steerpoints on your route particularly at home plate.
There are three types of check your lead can request from you:
1. Fuel state
2. Ops check
3. FOS (Fuel Onboard at Station)
Fuel state is simply the total fuel remaining on board. You find that one on the fuel quantity gauge, at
the bottom of the instrument on the digital readout.
•
Mamba flight, fuel state, Lead is 9.6
•
Two is 9.4
Ops checks are much more complete.
First the call has to be acknowledged:
•
Mamba flight, Ops check
•
Two
•
One is 28-32 10.4 feeding
•
Two is 28-32 10.2 feeding
The format is:
Call sign (Number in the flight), A/L needle value, F/R needle value, Total Fuel, Feeding if external
tanks are carried and feeding the internal wing tanks and Dry if the external tanks are empty.
Once Dry has been said once it does not have to be repeated.
An imbalance condition is illustrated on the fuel quantity gauge when the red portion of the needles is
visible, so each pilot can check it visually at a glance. Lead on the other hand has to ensure that the
difference between the A/L and the F/R needle values do not exceed 600 Pounds each way.
The FOS check is a request to check fuel reaching a specific waypoint (usually home) and it is
answered by giving the fuel state in the CRUS HOME page, ensuring that the correct steerpoint is
selected.
