How is lift achieved for in an aircraft?

Lift in an aircraft is achieved primarily through the shape of its wings, known as airfoils. As the aircraft moves forward, air flows over and under the wings; the wing's design causes the air pressure on top to be lower than the pressure on the bottom, resulting in an upward force called lift. This difference in pressure is influenced by the angle of attack, which is the angle between the wing and the oncoming airflow. By maintaining sufficient speed and angle of attack, an aircraft can generate enough lift to become airborne.
