produce optimum power; chnaging to coarser pitch would have that enginer power converted into more pull and consequently speed our rate of climb.
It was vital they mastered this technique if they were to keep uo in a battl climb or at high altitude.

To increase the performance of the Me 109 an increase in the revs for a short time at heights over 5.5 km. will be in future be
permissable. For the DB 601 A engine the normal maximum revs are 2400.
Above full pressure height they may be for a short time be increased
from 2400 to 2600...

...the excess revs can only be obtained by
means of the thumb switch after switching off the automatic device.
In doing this the danger of an additional impermissable increase in
the revs must be watched.

Sure I concure they are maintaining engine Rpm with pitch changes...
