Pitch is defined as the degree of inclination or slope. ... The propeller also has an angle of attack. ... An angle of attack measures the angle between the wind created by the plane's forward motion and the angle of the airfoil. ... The angle between the chord line and the direction of the air blowing past the wing, called the relative wind, is the angle of attack. ... The blade angle changes from the hub to the tip, with the greatest angle of incidence, or highest pitch, at the hub and the smallest pitch at the tip. ...
