The relationship between lift and angle of attack is that lift is directly proportional to angle of attack, particularly within certain limits. As the angle of attack increases, the airflow over the wings changes, leading to an increase in lift up to a point known as the critical angle of attack. At this stage, the wing is able to generate more lift due to the increased pressure difference between the upper and lower surfaces of the wing. However, it is essential to note that this relationship holds true until the critical angle is reached, after which excessive angle of attack can lead to flow separation and stall, causing lift to decrease.

Understanding this relationship is fundamental in aviation as it helps pilots optimize performance and maneuverability of the aircraft during various flight conditions. By manipulating the angle of attack through control surfaces, pilots can effectively control the aircraft's lift.
