When an aeroplane climbs (gains altitude),it has a nose-up altitude.This means that the nose of the plane is higher than the tail.Picture an airplane just after take off, as it climbs into the sky. The attitude of the plane,weather nose-up or nose down is called pitch.Pitch is controlled by the elevator,which is a horizontal surface located at the tail of an airplane.Airplanes also use ailerons to help control direction.Ailrons are located on the rear edge of each wing and can move up and down.When the airplane turns,the left and right ailrons move in opposite directions.One moves up the other moves down.Ailrons cause an aircraft to tilt to the left or right you have no doubt experinced this if you have ever been a passenger on an airplane.This left/right tilting moting is called roll.How is an airplane steared? Cars are steared by simply pointing the front wheels in the direction you wish to turn.Boats have a rudder at their stern or backend which controls their direction of movement.Like boats,airplanes also have rudders. The rudder is located at the end of the aircraft.The rudder is vertical and has a side-to-side motion that "stears" the aircraft to the left or right.This left/right steering motion is referred to as you.
