As an expert in the field of aeronautical engineering, I can provide a comprehensive explanation of how lift works on an airplane. Lift is the force that opposes the weight of an aircraft and allows it to rise into the air and stay there. It is generated by the pressure difference between the upper and lower surfaces of the wing.
The primary principle behind lift is Bernoulli's principle, which states that as the speed of a fluid increases, its pressure decreases. In the case of an airplane, the air is the fluid. The shape of an airplane's wing, known as an airfoil, is designed to take advantage of this principle.
The airfoil is typically cambered, meaning it is curved on the top and flatter on the bottom. This shape causes the air to move faster over the top surface of the wing than the bottom surface. As the air moves faster over the top, the pressure there decreases, while the pressure on the bottom of the wing remains higher. This pressure difference creates an upward force, which is lift.
However, the symmetric airfoil mentioned in the provided reference does not generate lift in the same way. A symmetric airfoil, where the upper and lower surfaces are mirror images of each other, does not have an inherent pressure difference across its surfaces. Instead, lift in such cases is generated primarily through the angle of attack, which is the angle between the wing's chord line and the relative wind direction. By increasing the angle of attack, the air is forced to move faster over the wing, creating the necessary pressure difference for lift.
This principle does not negate the ability of an airplane to fly upside down, as mentioned in the reference. When an airplane is inverted, the airflow is still able to generate lift because the shape of the wing and the angle of attack can still create a pressure difference. The lift force vector is always perpendicular to the wing's surface, and when the airplane is upside down, this vector points upward, allowing the aircraft to maintain altitude.
In addition to the angle of attack, other factors contribute to lift, such as the wing's area, the air density, and the forward speed of the aircraft. Pilots can manipulate these factors through control surfaces, such as flaps and slats, to increase lift during takeoff and landing, or to reduce lift for descent.
It's also important to note that while the lift is primarily a function of the wing's design and the airflow around it, the overall aerodynamic performance of the aircraft is influenced by other components, such as the fuselage, tail, and the interaction between all these components.
In summary, lift is a complex phenomenon that results from the interaction of the wing's shape, the airflow, and the angle of attack. It is a fundamental aspect of flight that allows airplanes to defy gravity and soar through the skies.

The symmetric airfoil in our experiment generates plenty of lift and its upper surface is the same length as the lower surface. Think of a paper airplane. ... This theory also does not explain how airplanes can fly upside-down which happens often at air shows and in air-to-air combat.Apr 5, 2018
