FOR SIMULATION PURPOSES ONLY
As the engine warms up, the RPM will creep up, this is normal and
acceptable; use the throttle to maintain a maximum of 1200 RPM. Confirm
that the oil pressure has reached a minimum of 25 PSI within 30 seconds.
If the oil pressure does not reach the minimum required, shut down the
engine and do not attempt to restart.
If the engine does not start after 10 seconds of cranking, release the starter
button. Check all the engine settings and, after allowing the starter motor to
cool for 30 seconds, attempt a further start.
If the STARTER caption does not go out, or it is suspected that the starter
motor is still engaged, turn off the GEN and BAT switches, and then shut down
the engine to prevent a fire.
Do not exceed 1500 RPM until ready for the engine test checks. RPM values
greater than this will cause excessive wear to a cold engine.
After Starting
Carry out the After Starting Checks. The ignition check is achieved by moving
the ignition switch from BOTH to R, back to BOTH, from BOTH to L and finally
back to BOTH.
The RPM should drop slightly on R or L alone but the engine should not stop. If
the engine cuts out then a dead magneto exists. If the RPM does not reduce
when selecting R and L, then a live magneto exists. In either case, shut down
the engine and have the fault rectified.
To check the correct operation of the flaps, select the flaps from UP to FULL
and then to UP whilst visually checking the flap movement on both wings and
the flap indication.
Taxiing
Do not wait for the engine to warm up but taxi as soon as possible. Set 1200
RPM, which is sufficient to start moving at max all up weight (AUW), then
reduce power to control the speed, using wheel brake if power alone is
insufficient to maintain a safe taxi speed.
Avoid using brake against power but caution should be exercised when
taxiing with a cold engine or tailwind, as RPM may drop below 800 with the
throttle closed.
