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:
“I candidly confess that I have ever looked on Cuba as the most interesting addition which could ever be made to our system of States. The control which, with Florida, this island would give us over the Gulf of Mexico, and the countries and isthmus bordering on it, as well as all those whose waters flow into it, would fill up the measure of our political well-being.”
—Thomas Jefferson (1743–1826)
