How does a pilot lower and raise the height of an airplane?

In general, the altitude of an airplane (how high it is above the ground) is controlled by a control surface known as the elevator.  This surface is on what is called the horizontal stabilizer (which is what most of us know as the horizontal part of the tail of the airplane).

When the pilot wants the airplane to go higher, he or she must make the elevator go up.  When the elevator goes up, the tail is pushed down and the nose up.  If the pilot also increases thrust, the airplane goes up.

To go down, the pilot must make the elevators go down.  This raises the tail and pushes the nose down.  A pilot can also descend simply by reducing thrust, which will also reduce lift.

A pilot can lower and raise the height of an airplane with the use of the control surfaces called the elevators. The elevators are horizontal panels attached to the tail section of the airplane. When the elevators are moved down, the tail of the plane moves up, its nose moves down and the airplane moves in the downwards direction. When the elevators are moved up, the reverse happens, with the tail of the airplane moving downwards and its nose moving upwards. This allows the airplane to move upwards. The elevators is this way allow the control of the airplane’s movement about the lateral axis.
