Bernoulli's principle is fundamental in understanding how lift is generated by an airfoil, such as an aircraft wing. This principle states that as the speed of a fluid (in this case, air) increases, its pressure decreases. When an aircraft flies, the wings are designed to create a difference in airspeed above and below the wing. The air moves faster over the top surface of the wing, resulting in lower pressure compared to the slower-moving air beneath the wing, which has higher pressure.

As the airspeed increases, the difference in pressure between the upper and lower surfaces of the wing also increases. This heightened pressure difference leads to an increase in lift. Therefore, when an airplane accelerates and the airspeed over its wings increases, the lift generated by the wings also increases, allowing the aircraft to rise more effectively into the air or maintain altitude with less angle of attack.

This increase in lift with higher airspeed is a key principle that pilots must understand for effective aircraft control during different phases of flight, especially during takeoff and transition into climb.
