How is lift achieved in an aircraft?

Lift in an aircraft is achieved primarily through the shape of the wings, known as airfoils. As the aircraft moves forward, air flows over and under the wings, creating a pressure difference: lower pressure on the top and higher pressure on the bottom. This difference generates an upward force, known as lift, which counteracts the weight of the aircraft and allows it to ascend. The angle of attack, or the angle between the wing and the oncoming airflow, also plays a crucial role in optimizing lift.
