1. Wings 3 MAIN MOVEMENTS

2. Flaps change the curvature of a wing, • increasing lift. • Airplanes use flaps to maintain lift at lower speeds, particularly during takeoff and landing. • This allows an airplane to make a slower landing approach and a shorter landing. • Flaps also increase drag, which helps slow the airplane and allows a steeper landing approach. Importance of Flaps

3. PITCH • ROLL • YAW Three basic movements of a plane

4. Yaw – • movement on the vertical axis. • The nose of the plane turns left or right. • Roll – • movement on the longitudinal axis. • One wing dips lower than the other. • Pitch – • movement on a lateral axis. • The nose of the plane moves up and down. 3 BASIC MOVEMENTS OF A PLANE

5. The movement around each axis is controlled by a specific control surface. • The pilot can use the elevators to control the pitch of a plane, the rudder to control the yaw, and the ailerons to control the roll. movement

8. Lift: • When air flows over the top of the wing of a plane, it needs to flow in a curved shape. • To do this, the pressure of the air right above the wing needs to be at a slightly lower pressure than the air above it, so the air will get pushed to flow around the wing. LIFT

9. This basic concept of lift can be applied to a frisbee as well. • The frisbee is Shaped so that the air travels faster over the top than under the bottom. • Hence, when the frisbee moves through the air, it rises. FRISBEE
