After taxiing for an extended period or at high power, run the engine
at 1000 - 1200 RPM for 2 to 3 min.
Close fuel shutoff valve.
6.7 Inflight Shut-Down and Restarting
Set throttle to idle, let engine cool down and switch off ignition.
To avoid windmilling bring propeller into feathered position. On aircraft with fixed
pitch propeller activate propeller brake or reduce speed.
Starting engine is the same as on the ground.
As long as the engine is still warm, do not activate cold start device.
If the engine is cold, perfom warm-up.
At low ambient temperatures and after prolonged soarings:
the engine oil may have cooled so much, that the engine cannot be started anymore
the capacity of the starting battery may be reduced (see section 8.22)
Make sure that you have sufficient altitude to restart the engine, especially
at low ambient temperatures and prolonged soarings.
6.8 Engine operation on hot days
The fuel pump operation may be disturbed because of vapor locks, when operating the engine on hot
days and/or in altitude conditions.
As a remedy we recommend retrofitting an additional electric fuel pump. Please consult your aircraft
manufacturer for additional information.
In general only such fuels approved by Limbach shall be used (see section 10.2)
