2. Structure of an Aircraft: Thrust is generated by a propeller or jet turbines

3. Forces Acting On An Aircraft:

4. What Creates Lift?

5. *YOU CAN CONTROL LIFT BY CHANGING THE ANGLE OF THE AIRPLANE'S WING RELATIVE TO THE WIND OR BY INCREASING OR DECREASING AIRSPEED. *YOU CAN ALSO CHANGE THE SHAPE OF THE WING BY LOWERING THE FLAPS WHICH EXTEND THE AREA OF THE WING. *KEEP IN MIND THAT ANYTIME YOU DO SOMETHING TO CHANGE LIFT, DRAG IS AFFECTED. *FOR A GIVEN LIFT-TO-DRAG RATIO, IF YOU INCREASE LIFT, DRAG INCREASES. DRAG IS ALWAYS A BY-PRODUCT OF LIFT. This is known as Bernoulli’s Principle:

6. Direction Changes:

7. Changing Direction: – Airplanes change flight direction on 3 axis: – Yaw is controlled by the rudder (vertical axis) – Roll is controlled by the ailerons (longitudinal axis) – Pitch is controlled by the elevators (lateral axis)
