FLIGHT MANUAL
Determination of fuel contents (continued)
b) Wing tank(s) (option)
The fuel content of the wing tank(s) is not measured. Therefore the amount of
fuel filled into the wing tank(s) has to be determined during refuelling.
Entering total amount of fuel filled into all tanks
It is possible to consider the amount of fuel filled into the wing tank(s) at the
amount of fuel displayed on the engine control unit MCU II.
To do so, scroll through the display of the engine control unit MCU II with the
Menu-button until “FUEL” is displayed while the power plant is retracted.
Release the Menu-button shortly and then press the button again for 5 s as
done for the calibration of the fuselage tank to select this menu item.
Subsequently the total amount of fuel in the wing tank(s) and the fuselage tank
can be entered by further pressing the menu-button. If the menu-button isn’t
pressed for at least 5 s, the entered amount of fuel will be adopted and
displayed on the engine control unit MCU II.
The fuel consumption of the power plant is measured with a flow rate meter
while the engine is running. The indicated total fuel content of wing and
fuselage tank(s) on the MCU II considers the amount of fuel consumed while
the engine is running.
If the fuel content of the fuselage tank drops below 6 l, only the fuel content of
the fuselage tank will be displayed on the engine control unit. If the fuel
content in the fuselage tank will climb again over 6 l (because of bleeding fuel
out of the wing tank(s) into the fuselage tank), the total amount of fuel in all
tanks will be displayed again.
