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.
