Technical data
When using other than introduced airscrew, especially 3blade is the real gliding range by no load
engine slightly higher / principle of bigger tension/. and with turned off engine slightly lower /
the principle of higher aerodynamic force /
5.6 Length of start
Introduced length of start is prescribed for the maximum weight 450kg, by dead calm, dry,
straight and shortly cut lawn, with the position of lifting flaps prescribed for the start. There is
prescribed the value of sticking off the launching area and for reaching the height of 15m.
Engine After sticking off Across the obstruction at the height of 15m
912 90m 270m
912S 75m 220m
5.7.Landing length
Introduced length of landing is prescribed for the maximum weight of 450 kg, by dead calm, dry
and straight and short cut lawn and with the position of lifting flaps prescribed for the landing.
There is a value for maximum effective braking / without blocking the wheels / and for the
landing without using the brakes.
The length of landing with using the brakes 100m
Length of landing without using the brakes 300m
Do not forget the landing length will expressively elongate, if you try to land with wind in the
back. If it is only possible, land always against the wind.
5.8.Flight persistency
The persistency means the time of the flight which the airplane can fly without refilling the fuel.
It is also a quotient of depleted volume of the fuel in tanks and the lowest hourly consumption.
The efficient speed is pretty low and is not introduced in this handbook in order not to lead to
flying at this speed in unquiet atmosphere. Do not replace the technical term of persistency for
the real maximum length of flight which you can usually reach.
At the airplane of factual configuration /engine+airscrew+weight / the persistency expressively
depends on the technique of the pilotage. Consider the data about the persistency of flight as
informative. For the engine Rotax 912 and 912S is the flight persistency about 5.9hours.
The economics of the flight depends expressively on the effectiveness of the work of the
airscrew. There are optimal revolutions of the airscrew and setting of the blades for each speed of
the flight, when the airscrew has the biggest effectiveness. Lower, there is a table for the airscrew
SR 2000xa.
