some 2500 RPM as this will provide some airflow from the propeller to the
radiators and the temperatures will not rise so quickly. Should you see en-
gine temperatures exceed safe operational values, shut o the engine, point
the aircraft’s nose into the wind and wait for the temperatures to reduce.
9.4 TAKE OFF AND INITIAL CLIMB
Having checked and set all engine and aircraft parameters, you should be
ready for take o by now. Reverify fuel valve is open. Trim lever should be
in the middle.
Start the take-o roll gradually. Keep adding throttle smoothly and slowly
to full power. There are two reasons for this. First, you change flight stage
from zero movement to acceleration slowly; this provides you with time to
react to conditions. Second, especially if taking-o from a gravel runway, this
method of adding full throttle will prevent the little stones on the runway to
damage the propeller. Extremely short runways are an exception. There you
should line up the aircraft, set flaps to 2nd stage, step on the brakes, apply
full power and release the brakes. As you start to move, pull the stick 1/3 of
elevator’s deflection backwards to ease the pressure on the nose wheel and
lift it o the runway slightly. Do not use full back deflection as this will cause
the aircraft’s tail to touch the ground.
When the nose wheel has lifted o the ground, there is nothing else but to
hold the same pitch attitude and the aircraft will become airborne. Cross-
wind take-os, depending on wind strength, require a little bit of aileron de-
flection into the wind. Remember, wings must stay level throughout ground-
roll, rotation and initial climb!
Having lifted o the ground, gently push the stick forward just a bit to accel-
erate. At some 110 km/h (60 kts) set flaps to 1st stage, at 130 km/h (70 kts) set
them to neutral.
9.5 CLIMB
A comfortable setting for climb is flaps in zero/neutral position, speed of
76 kts (140 km/h) at or slightly below 5500 RPM. In summer time or when
outside temperature exceeds 85° F (30°C) you should consider climbing at
some 85 kts (160 km/h) to provide more airflow to the engine radiators. Trim
the aircraft for comfortable stick forces.
