Directional static stability
Webdescribes the aircraft’s directional static stability. The main contribution to Nv is usually from the fin and its value is proportional to fin area. Hence, if the aircraft has a large fin, Nv may fall out with the range given above. This will lead to unstable spiral mode, hence making the aircraft dynamically unstable. s, 1... .. .. . WebJust as a horizontal tailplane gives longitudinal static stability to an aircraft, so a vertical tail fin provides directional static stability, and it is the component of the aircraft which provides the principal stabilizing effect in this mode. If a vertical tail fin on an aircraft which is sideslipping to the left, i.e., yawed to the right.
