Sidewash Angle in Directional Stability Formulas
Sidewash Angle is caused by the flow field distortion due to the wings and fuselage. It is analogous to the downwash angle for the horizontal tailplane. And is denoted by σ. Sidewash Angle is usually measured using the Radian for Angle. Note that the value of Sidewash Angle is always negative.
