4.10 Climb
The wing flaps should be retracted after takeoff at 150 ft (50m) of height
above ground and you should have a speed of around 62 KIAS, 115 km/h,
71 mph. This is the best rate of climb speed at which the airplane climbs at
more than 750 ft/min at 2000 ft IAS. After achieving the best rate of climb
speed, adjust the trim control force and make climbing more comfortable.
Refer to the Aircraft Operating Instructions (Airplane Flight Manual),
Section 5. Performance for the best rate of climb speeds at various
altitudes of International Standard Atmosphere (ISA).
If your airplane is fitted with an in-flight variable pitch prop, the pitch set for
takeoff is minimum. In this case the maximum allowable time at maximum
takeoff power is 5 minutes and then you must reduce the engine power by
selecting a coarser pitch or by reducing power with the throttle. Then the
maximum continuous power is 5500 rpm.
If there is a fixed pitch prop or a ground adjustable prop in your airplane,
then the engine speed even at full throttle does not exceed 5500 rpm
(maximum continuous power). In this case you are not limited by the
duration of the climb as in the case of an in-flight adjustable prop. However,
oil temperature and pressure and cylinder head temperatures should be
monitored from time to time to keep the engine operating within its limits, as
stated hereafter.
You must monitor from time to time the oil temperature and pressure and
the cylinder head temperatures, especially during a longer climb, to check
whether the engine is operating within its limits (there are color coded arcs
marked on oil temperature and CHT gauge, the green arc is for the normal
operating range, the yellow arc marks the temperature range which
requires caution - you should not operate the engine within the yellow arc
for a long period of time ). If temperatures approach the end of the yellow
arcs marked by a red radial, then you should lower the angle of climb,
reduce engine power and increase airspeed to allow better engine cooling.
The Sportstar angle of incidence is relatively high during a climb at full
power and you may be surprised by that, especially if you have flown
mainly General Aviation aircraft (e.g. Cessna etc.). Steep angles of climb
occur in this category of aircraft (Ultralight or Light Sport) equipped with a
powerful engine (e.g. Rotax 912). You may also be surprised by how fast
the airplane lifts off the ground. (appox. 7 seconds).
