How Does a Pilot Control an Airplane?

Moveable surfaces on an airplane's wings and tail allow a pilot to maneuver an airplane and control its attitude, or orientation. These control surfaces work on the same principle as lift on a wing. They create a difference in air pressure to produce a force on the airplane in a desired direction.

The main purpose of the tail is to provide stability. If tilted by a gust of wind, a stable airplane tends to recover, just as a ball lying at the bottom of a bowl will roll back to the center after being disturbed.
