5.1.5. Option 1: Fuselage Tanks
The two fuel tanks are mounted behind the pilots seats. The fuel valve (ROTAX only) is located at the center console
with positions ON and OFF. The version with SMART engine has no manual fuel valve because its electrical fuel pump
closes the fuel line as soon as the ignition is switched off. One fuel drain valve is located at the lower fuselage forward o f
the main landing gear.
Fuel quantity is indicated by a gauge at the tank. After refueling, this indication is accurate after both tanks have leveled.
This can take up to 5 minutes.
Although the fuel cap has a water drain, it is recommended to secure the cap from water entering during strong rain by
putting an extra cover on top of the cap when the aircraft is parked.
