Fuel Management
The return line directs fuel to the left fuel tank only. The left tank must be used for all takeoffs, initial flight and
landings. Use the left tank until 1/2 of its capacity is consumed before changing to the right tank. This procedure
makes enough space in the left tank for returning fuel.
For maximum fuel utilization, when LH reserve warning lights illuminates, switch to the right tank and consume all
available fuel. In horizontal flight it is possible to consume almost all the fuel in the tank. After the right fuel tank is
empty, switch to the left tank.
CAUTION
Unconsumed fuel is returned to the left fuel tank only. Monitor
the fuel levels in the tanks during flight to avoid venting it
overboard!
CAUTION
The left fuel tank must be used for all takeoffs and landings as the
electric fuel pump operates on the left fuel tank only!
Fuel Measurement System
There is a fuel float type of fuel level sensor in the both left and right fuel tank. Fuel level sensor is installed in the root
rib of fuselage fuel tanks.
Fuel quantity is displayed by Dynon SkyView SV-D1000. Due to the fuel tank geometry and position of fuel level
sensor, it is possible to indicate the fuel quantity only in the range 0
– 45 l. If the fuel quantity in the tank is above 45 l,
Dynon SkyView SV-D100 0 displays “45+” . Determining of fuel quantity in the tank above 45 l is possible only on the
ground by using a dipstick (Fig. 7-26).
The fuel
level sensors are calibrated in the aircraft’s level position to indicate the correct fuel quantity during
horizontal flight. The dipstick is calibrated in the aircraft’s parking position on a level surface to indi cate the correct
fuel quantity in the RH tank above 45 l during refueling.
LH/RH fuel reserve warning light illuminates when the fuel quantity goes below 16 liters / 4.23 U. S. gal in each tank
(aircraft in level flight). The fuel in each tank is sufficient for half-hour flight at maximum continuous power.
