What happens to the pressure below the wing as the angle of attack increases?

As the angle of attack increases, the pressure below the wing typically decreases. This is due to the principles of aerodynamics associated with lift generation. When the angle of attack rises, the airflow over the wing becomes more inclined. This increases the velocity of the airflow over the wing's upper surface, which, according to Bernoulli's principle, results in lower pressure on top of the wing.

At the same time, the airflow below the wing does not accelerate as much, leading to relatively higher pressure than that above the wing. Hence, the pressure difference between the top and bottom surfaces increases, contributing to lift. The correct answer indicating that pressure below the wing decreases aligns with the simulation of airflow patterns as the wing's angle of attack is adjusted. Understanding this relationship helps in grasping the fundamental principles behind lift and the performance of an aircraft during various phases of flight.
