FOR SIMULATION PURPOSES ONLY
Check the nose wheel steering and brakes for correct operation as soon as
practicable. Confirm the correct functioning of the flight instruments as the
opportunity arises on taxiing.
Full deflection of the rudder pedals will deflect the nose wheel sufficiently for
most turns; for a tighter turn also apply brake on the inside wheel but avoid
locking the wheel as this may cause tyre damage.
The aircraft is not to be operated when the wind is gusting at, or in excess of,
40 kts. on the ground.
When taxiing crosswind in high winds there may be a tendency for the into-
wind wing to lift; full aileron deflection may be required to counter this
tendency.
Testing the Engine
Test the engine in accordance with the checklists, with the nose wheel
straight and keeping the control column in the central position. Keep the
ground operation of the engine at high power to a minimum to avoid
overheating.
When exercising the propeller RPM control, ensure that the lever is operated
throughout its range and that the RPM changes by 500, but no more. This
allows maximum circulation of the oil between the engine and propeller and
prevents a build-up of sludge within the propeller pitch change mechanism.
Whilst testing the magnetos at 2000 RPM, if the ignition switch is inadvertently
selected to OFF or if the engine cuts dead, do not reselect the switch to
BOTH. Allow the engine to run down and then restart.
To set BPM before take-off, apply full power with the aircraft stationary and
adjust the mixture to the placard fuel flow appropriate to the altitude less 4
lph.
For example, at sea level set 55 lph. After setting BPM and before reducing
power, confirm that 2350 RPM minimum is indicated.
