This procedure is applicable for Jabiru Aircraft equipped with wing tanks and electronic fuel gauge
senders.
This procedure must be carried out during initial assembly of a new aircraft or when a new gauge
sender is fitted.
The accuracy of the fuel indication system of the aircraft depends on careful and accurate completion
of this process.
For this procedure the fuel tanks need to be filled from empty. Therefore, they must be emptied now.
Apply fuel line clamps to close the fuel lines between the wing tanks and the header tank.
Before starting the fuel gauge calibration the aircraft needs to be laterally (left/right) level. See the
aircraft flight manual for the levelling datum details.
Add 1.5L of fuel to each tank, this is the unusable fuel. Check the indication of the fuel gauge. The
fuel gauge needle must be pointing at the E or below. If it is not then the gauge unit will need to be
removed and adjusted. See Figure 27
– with the tank containing the unusable fuel amount the
needle must indicate a position between the two extremes shown.
Accurately add 20L into the tank (on top of the unusable fuel). Then take the fuel gauge calibration
decal (see Figure 28) and align inner fuel gauge dial representation with the 20L mark in the location
indicated by the pointer in the fuel gauge. Repeat for the second tank. Make sure the decals are
marked to indicate which tank they are matched with. In Figure 29 (left) a typical sender indication
with 20L added is shown. Note how the needle is just slightly above 1/4. In Figure 29 (right) a decal
assembly to match this indication is shown. The 20L arrow, on the outer, indicates just above the ¼
mark on the inner.
CAUTION
There is often a degree of friction within the gauge sender. Tap gently with a finger after adding
fuel to maximise accuracy of reading.
WARNING
Before removing clamps on the fuel line make sure all fuel lines are connected.
On removal of clamps check that the fuel lines are not damaged and return to their original shape
