Simulated Fuel Tank
1. Make sure that aircraft is in level position for a cruise flight.
2. Select one of the predefined shapes from the list.
3. Make the tank empty – drain all fuel out.
4. Select the
Empty/Full
option and set the sensor value for the empty
tank.
5. Fill up the tank and then sent the full case.
6. Close the window.
There is also an alternative way for this. It can be used when sensor values
for empty and full are known and you are sure that they do not vary from
sensor to sensor. In this case:
1. Select a predefined shape,
2. Select the
Empty/Fuel
option.
3. Select the
Empty
and enter the min (empty) sensor value.
4. Repeat this for the
Full
and enter the sensor value.
5. Close the window.
The tank shape has now been defined and scaled to empty and full sensor
position.
Predefined shapes also support the
Edit
option, where individual points can
be adjusted. Since this alters the shape, the shape name will change to
User
automatically.

Simulated Fuel Tank
Software fuel tank simulation is used when no fuel level sensors were config-
ured. Selection of the
Tank
icon opens a simple window, which accepts the
fuel tank capacity. Figure 71 shows situation for the 80 liters fuel tank.
Using simulated fuel tank can be dangerous. The fuel remaining is calculated
from initial estimated fuel quantity and fuel consumption. Both, initial esti-
mate and fuel consumption can be wrong, which may lead to indicate more
fuel remaining that it really is.
When the simulated fuel tank is used, a high quality fuel flow meter is rec-
ommended. Do not use the simulated fuel tank with software based fuel flow.
