Handling of the wingtank:
To fill or empty the tank, the respective fuel
valve (19) must be open and the pump must
be switched to the
”up“
or “down” position.
Filling of the wintank has to be done on
ground with at least 20 liter of fuel in the main
tank. The wingtank is full as soon as fuel is
flowing via the overflow / vent (23) into the
vent system (8) of the main tank. Now the
pump has to be switched off and the valve
must be closed.
During flight, the fuel can be pumped out of
the wingtank as soon there is space of at least
20 liter in the main tank.

Brakes
Brakes are controlled by a handle at the center console. Brakes are applied
to both main wheels at the same time.
By closing a valve at the center console when pressure has been applied,
the hydraulic brake can be function as a park brake.
CAUTION (only models manufactured before November 2005): if the valve is
closed (park brake set), the brake handle is without function. In case the
aircraft starts to move with park brake set, the valve must be opened and the
brake handle pulled. Thereafter the valve can be closed again.

Electrical System
A detailed schematic of the electrical system is available under
, section
”manuals“
.
A 12V engine-driven alternator delivers the required electricity.
If the red generator control light lights up above 1800 RPM, (or SmartMIP
gives a warning) shut off all electrical equipment not required for flight as the
battery is discharged.
With Smart engine installed, land immediately as the engine ignition is
powered by battery. The engine will stop as soon as the battery charge is
exhausted.
Depending on the rating and charge status of the built-in battery as well as
engine RPM, the engine can be expected to work for the indicated periods
following a power generator fault (assuming that the battery is fully charged):
