Sideslip angle

From Wikipedia, the free encyclopedia

In figure (a) an airplane flies so that the sideslip angle is zero, in figure (b) it yaws to have a positive sideslip angle. The circular arrow shows the moment needed for directional stability. Credits: NASA

This article is about aviation. For car handling, see Slip angle.

Not to be confused with Yaw angle.

Sideslip angle relates the displacement of the aircraft centerline from the relative wind. In flight dynamics it is given the shorthand notation $β$ (beta) and is positive when the relative wind is displaced to the right of the airplane centerline. The sideslip angle $β$ is essentially the directional angle of attack of the airplane and is the primary reference in lateral stability as well as directional stability considerations.^[1]
