Prop Pitch
As we already have a very interesdting thread here, would it be possible to sort the prop pitch out here?

In theoretics i would say the prop pitch is similar to a gear in a car.
But i still dint find an effective way to use it properly in a Bf109.
So could someone explain when should i why set the prop pitch to what position.
I read the manualö and the few line about the prop pitch ,nevertheless i am sure this can´t be all.
