What happens when the angle of attack is increased before reaching stall?

When the angle of attack is increased before reaching the stall condition, it enhances lift up to a specific point known as the critical angle of attack. As the angle of attack increases, the airflow over the wings changes, which can lead to an increase in lift due to the greater pressure difference created between the upper and lower surfaces of the wing. This is a fundamental principle in aerodynamics that allows an aircraft to gain altitude and improve its performance while still within safe operational limits.

However, it is important to note that there is a threshold; beyond the critical angle of attack, the airflow begins to separate from the wing surfaces, resulting in a loss of lift and potentially leading to a stall. The range of effective angles of attack is crucial for pilots to understand, as it directly influences both the control and performance of the aircraft during flight.
