23. The wheels continue to rotate after liftoff from the ground and
moderate vibration of the airplane may occur if the wheels (tires)
are not balanced. If this is caused by the main wheels then apply
pressure to the toe-brakes for a short period of time to stop the
wheels rotating. This technique of course cannot be used for the
nose wheel. Braking the wheels to stop vibrations immediately after
takeoff is not recommended during winter because if the takeoff run
had been started in slush or wet snow, the early braking would stop
the centrifugal force of the tires turning. This centrifugal force will
help to clean the slush off of the wheels. If the water stays on the
wheels, it could later freeze up at low temperatures.
24. Slowly retract the flaps after you reach approximately 150 ft(50m )
of height above ground (slowly to prevent the airplane from
rocking).
25. Adjust the power by the throttle lever as needed-you can climb at
maximum Takeoff power (5800 rpm) for 5 minutes. When a fixed or
ground adjustable prop is installed you will not be able to reach this
rpm so you are not limited by that time, however observe oil and
cylinder head temperatures to make sure that they do not exceed
the limits.
26. Adjust the elevator trim as necessary.
27. Climb to desired altitude.
The best rate of climb speeds vary with altitude and may be found
in the Aircraft Operating Instructions (Flight Manual) in section 5.
Performance. For the Sportstar the best rate of climb speed is
around 62 KIAS, 115 km/h, 71 mph. After retracting the wing flaps
you are not limited by the maximum flap extended speed VFE 70
KIAS, 130 km/h, 81 mp/h thus you can climb even faster.
If an in-flight variable pitch prop is installed in your airplane (which
is not permitted in the LSA category), then with the propeller pitch
control, set the takeoff angle (minimum pitch). After setting
minimum rpm, the engine speed may reach up to 5800 rpm during
a climb. The engine must not be at 5800 rpm for longer than 5
minutes, so then the pilot can reduce the rpm to 5500 by selecting
a coarser pitch. 5500 rpm is the maximum continuous power for the
Rotax 912. At this engine rpm you may climb without restriction,
however you must monitor the oil and cylinder head temperatures.
