3.
Switch off 1
st
ignition circuit
maximum RPM drop 300 RPM
4.
Switch on both ignition circuits

Note: The RPM speed difference between ignition circuits running separately must not be more
than 120 RPM.
6.
Left and Right fuel tank check
during engine run, the fuel pressure must not drop below
the allowed value in either of fuel tanks in use. During the change-over of fuel tank, a short-
term pressure drop may occur, but after the fuel tank is selected, the pressure shall increase
back to appropriate values.
7. After the engine check is made, the take-off shall be performed within max. 5 min. after
reaching the operating temperature. In case of long lasting standing on spot when engine is
running, the engine is not sufficiently cooled by the airflow and so the overheating and
damage of the engine may be caused! Due to overheating of the engine, the composite
structure of the aircraft may be damaged in the area of engine compartment too.

Take-off
and Climbing
Release the brakes. Make the aircraft move by accelerating until the maximum throttle position is
reached. Control stick is in neutral position. Control the front wheel and the rudder as to keep the
aircraft within the runway axis. When reaching the speed of 45 kt, lift up the aircraft off the ground
and continue take-off up to the speed of 59 kt. Then, gently pull the control stick to start climbing by
optimum speed of 59 kt. After reaching the stable climbing speed of 59-65 kt and over 160 ft of
altitude, retract the flaps fluently. During the take-off, the engine operating limits must not be
exceeded. After reaching 1000 ft GND altitude, you can switch off the second fuel pump.
