Doors
The doors can be opened and locked from inside with a handle. The pilots
(left) door can also be opened / closed and locked from the outside. Both
doors have a small perspex vent. Doors can be removed completely.
Without doors, the airspeed must be limited to 100 km/h.

Engine
The engine is a ROTAX 912 UL / 912 ULS four-cylinder, or a three cylinder
M160 (smart) engine with turbocharger. The ROTAX has a combined cooling
by liquid and air, the smart engine is fully liquid cooled. To shutdown the
ROTAX it is recommended, to switch off one ignition circuit by using the
ignition test switch before shutting down the engine completely.
The control levers for choke (ROTAX only), carburetor heat (if installed) and
throttle are located below the instrument panel.
The engine cowling can easily be removed for maintenance and checks. Oil
and coolant can be checked by opening a small cap on the right upper part
of the cowling.

Fuel System
The FK 9 ELA is equipped either with fuselage (Option 1) or with wing tanks
(Option 2). There is one engine mounted mechanical fuel pump normally
providing fuel to the ROTAX engine.
Additionally there is an AUX electrical
fuel pump which should be ON during takeoff and landing.
The smart motor is fuel injected and has its own electric fuel pump and filter.
Fuel low Pressure Warning:
One (optional) fuel pressure warning light, the MID or the MIP indicate fuel
pressure below minimum. In this case with the ROTAX motor, switch on the
AUX electrical fuel pump.and select the fullest tank.
Fuel Quantity Indication:
Beside the gauges at the respective tanks (see option 1+2), there is an
optional fuel quantity indication at the MID / MIP. This indication derives the
information from two different sources, depending on the system installed:
a) the pilots inserts the fuel quantity before takeoff and the MID / MIP
computes the remaining fuel using the fuel flow sensor
b) fuel level sensors are installed in the tank and transmit fuel quantity to
the MID / MIP
The fuel quantity indication on the MID / MIP offers a rough estimate of the
current fuel on bord. The accuracy of the system is not sufficient for flight
planning purposes.
