2.4.1.Fuel tank capacity
Total volume of tanks 68litres
Unexhaustible supply 3litres
Minimum amount of fuel when taking off 8 litres
Unexhaustible amount of fuel is such amount of fuel in the tank in which can occur first
symptoms of the lack of the fuel at normal conditions.
2.4.2.Consuption of fuel
The consumption of fuel expressively depends on the type of used airscrew, engine, for factual
airscrew and engine then on the technique of pilotage, total weight of the airplane, height of
the flight, flight regime and the consumption is expressively influenced by the meteorological
conditions / the consumption is increasing with higher temperature /. In general, flight with
heavier airplane requires higher engine output because for reaching needed rising force it
needs to be progressed with bigger angle of incidence, so the aerodynamic resistance is higher.
Aerodynamic resistance is also increasing with second power of the speed of the flight and
that´s why the consumption of the fuel is increasing with higher speed. The consumption-
output of engine curve is enclosed in the instruction for maintenance for the engine. Also used
airscrew expressively influences the consumption. Positioning the angle of incidence of the
airscrew blades can be a compromise among many various flight regimes at stationary or
adjustable airscrews. Using adjustable airscrew can the consumption decrease by 10-15%.
The average consumption for steady running flight with the speed of 170km/per using the
engine Rotax 912 or 914 and using the on land adjustable 3blade airscrew at the weight of the
airplane 450kg.
With using the fuel computer, which also evaluates the immediate hour consumption of the
fuel, you can, for factual conditions, optimize flight regime and achieve that way another
reduction of the consumption.
Remark: In this context it is much more interesting for traveling the consumption of fuel per
hour, the consumption of fuel to indicated 100km of flight, so the portion of the fuel in litters
and indicated aerial speed in hundreds of kilometers.
Whilst consumption of the fuel for and hour of flight enables us to find out how long you can
keep in the air, the consumption of the fuel for 100kilometres tells us what indicated aerial
distance the airplane can fly. The flight at minimum consumption for 100km represents the
most valuable way of flight for actual trace. You will find out later, that the consumption of
17litres for 1 hour at the speed of 195km/h is more valuable than seemingly low consumption
of 12 litters per hour at the speed of 120km/h.
