How is lift generated on a wing?

Lift is generated on a wing primarily due to the difference in air pressure above and below the wing. This phenomenon is explained by Bernoulli's principle, which states that as the speed of airflow increases over the curved upper surface of the wing, the pressure decreases. Conversely, the pressure below the wing remains relatively higher due to slower airflow. This pressure difference creates an upward lifting force that allows the aircraft to rise and stay airborne.

The wing's airfoil shape is integral to this process, as it is designed to enhance the airflow characteristics and maximize lift while minimizing drag. The angle of attack, which is the angle between the chord line of the wing and the oncoming airflow, also plays a critical role in increasing lift up to a certain point before flow separation occurs and stall may happen.

In contrast, thrust generated by the engines, the shape of the aircraft fuselage, or the weight of the aircraft, while having important roles in flight dynamics, do not directly create lift. Thrust propels the aircraft forward, while the fuselage shape affects drag and overall aerodynamic efficiency. Weight is a force that acts downward and must be overcome by lift for the aircraft to ascend. Thus, the lift generated by pressure differences is the fundamental mechanism that allows
