 The name is self-descriptive here. A input can be given to change the pitch of a propeller. That way a constant speed propeller can be controlled by a [[governor]], reversed into beta or reverse thrust or feathered. The name is self-descriptive here.

 +==== CutOut ====
 +
 +This is the fraction of the radius (or maybe the fraction of the area) that is not part of the propeller because of the propeller hub and spinner. The model used in the Aerofly FS 2 accounts for that blade-less portion by the ''CutOut'' scalar.
