Directional Stabilization and Control
"Directional (or yaw) stability is usually provided by the fin and rudder together forming a total surface", the vertical stabilizer. Directional control is obtained with the use of the rudder, a movable surface at the rear of the fin. Less commonly, the whole fin surface is pivoted for both stability and control. Yaw stability makes aircraft tend to turn into gusts, rather than being deviated by them.

Famous quotes containing the word control:
“If someone does something we disapprove of, we regard him as bad if we believe we can deter him from persisting in his conduct, but we regard him as mad if we believe we cannot. In either case, the crucial issue is our control of the other: the more we lose control over him, and the more he assumes control over himself, the more, in case of conflict, we are likely to consider him mad rather than just bad.”
—Thomas Szasz (b. 1920)
