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:
“The inability to control our children’s behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. That’s what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.”
—Elaine Heffner (20th century)
