What is the pitch of a aeroplane?

The pitch of an aeroplane is the angle at which it climbs or descends. Pilots control the aircraft with a control column or a "stick". When they move the column to the rear, we say that we "pitch the nose of the aircraft up", meaning it is now climbing. Likewise, if a pilot says "pitch the nose down", it means the column must be pushed forward to achieve a descent attitude. The control column is connected to the elevator (on the tail of the aeroplane). This acts as a tab that when "pitched up" it moves down, increasing the angle of attack on the tail, and generates more lift so that the aircraft cn climb. A trim tab is attached to the elevator which can be adjusted to match the amount of pressure put on the control column. By adjusting this, the pilot can let go off th control column and th aircraft will continue to fly in the same heading and pitch as it was left.
