When airflow over a wing is disrupted, lift degenerates rapidly due to the loss of smooth, streamlined flow that is necessary for generating lift. Lift is primarily created when the air pressure above the wing is lower than the pressure below, which is facilitated by the shape of the wing and the speed of the air passing over it. Disrupted airflow disturbs this pressure difference, reducing the efficiency of the wing in generating upward force.

Factors that can cause airflow disruption include turbulence, stall conditions, or obstructions on the wing's surface. Once the airflow is disturbed, the wing is unable to maintain adequate lift, leading to a swift decrease in flight capability. This principle is crucial for pilots to understand, particularly when maneuvering the drone or during takeoff and landing phases, as it directly impacts the aircraft's performance and stability. Understanding the consequences of disrupted airflow helps pilots maintain safe and effective control over their drones.
