Yaw Turn!
By Trista L. Pollard
  

1     When you ride in your parents' car, you may notice the car making specific motions- forward, reverse, left turn, right turn, and stop. Well, airplanes make three basic movements while flying called pitch, roll, and yaw.
 
2     The pilot of an airplane helps to balance the four forces of flight- gravity, lift, thrust, and drag. A plane is balanced when its center of gravity is at the same point as its center of lift. The center of gravity is the point where the mass of an airplane is concentrated. That is the point where the majority of the plane's weight is located. The center of lift is the point where the airplane's total lift is concentrated. That is the point where the highest amount of upward force on the plane is located. When both are at the same point, the plane is balanced or in level flight.
