coarse pitch

coarse pitch
Making a large angle between the blade chord and the plane of the propeller disc, thus producing a high forward speed for a given rotational speed. Unlike at takeoff and landing, when forward air speeds are low and the propeller pitch is fine, the blade angle needs to be increased as the speed increases, or coarsened, for the angle of attack to remain optimum. The change of pitch may be done automatically by a constant speed unit or manually in a variable pitch propeller.
