CAUTION
The starter should be activated for a maximum of 10 sec., followed by a 2 min.
pause for starter motor cooling.
After starting the engine, adjust the throttle for smooth running between 2500-
2750 rpm. Check the oil pressure, which should increase within 10 sec.
Increase the engine speed after the oil pressure has reached 2 bars (
29 psi
)
and is steady.
To avoid shock loading, start the engine with the throttle set for idle or a
maximum of 10 % opened, then wait 3 sec to reach constant engine speed
before opening the throttle further.
4.4.4 Engine Warm-up and Check
Chock the main wheels before engine check. Initially warm up the engine at 2000
rpm for two minutes then continue to 2500-2750 rpm until the oil temperature
reaches 50°C (
122 °F
). The warm up period depends on ambient air temperature.
Check both ignition circuits at 4000 rpm. The engine speed drop with either
magneto switched off should not exceed 300 rpm. The maximum engine speed
drop difference between circuits A and B should be 120 rpm.
Set max. power to check max. speed with given propeller; check engine
temperatures and pressures.
Check pick up (acceleration) from idle to max. power. If necessary, cool the
engine at 3000 rpm before shutdown.
CAUTION
The engine check should be performed with the aircraft heading upwind and
not on loose terrain (the propeller may draw in debris which can damage the
leading edges of the blades).
4.4.5 Taxiing
The recommended taxiing speed is 9 mph. The aeroplane can be steered either
by the steerable nose wheel or by its brakes, or a combination of both. Hydraulic
disc brakes are controlled by toe levers on the top of the rudder pedals.
