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:
“To try to control a nine-month-old’s clinginess by forcing him away is a mistake, because it counteracts a normal part of the child’s development. To think that the child is clinging to you because he is spoiled is nonsense. Clinginess is not a discipline issue, at least not in the sense of correcting a wrongdoing.”
—Lawrence Balter (20th century)
