How do pilots steer a plane?
Pilots steer using moving panels. The ones on the tail tilt the nose up and down, the ones on the wings roll the plane left and right, and the one on the tail fin swings the nose from side to side.
A plane steers with moving panels on its wings and tail: elevators tilt the nose, ailerons roll the plane and the rudder swings the nose from side to side.
Three ways to move
Pitch is the nose going up or down. Roll is one wing dipping while the other rises. Yaw is the nose swinging left or right.
The panels
Elevators on the tail control pitch. Ailerons on the back of the wings move in opposite directions to control roll. The rudder on the tail fin controls yaw. Flaps on the wings are lowered for take-off and landing to give more lift at low speed.
How a turn really works
A plane turns mostly by banking: it rolls one wing down so that the lift pulls it sideways. The rudder only keeps the turn smooth.
