WARM-UP and FUNCTIONAL CHECK
Warm-up the engine with a fast idle of 1000 - 1200 RPM until the oil temperature
reaches 50 degrees C. During this phase, the cooling of the cylinder head is
insufficient due to reduced airflow across the cylinders. It is therefore advisable not
to shorten the warm-up time by running the engine at higher RPM. The aeroplane
should be pointed into wind to allow additional cooling air. As soon as the oil reaches
50 degrees C, it is possible to do the run-up.
