What does the term "stall" refer to in aviation?

In aviation, the term "stall" refers specifically to a disruption of airflow over a wing, leading to a loss of lift. When an aircraft exceeds its critical angle of attack, the smooth flow of air over the wing is disrupted, resulting in a significant reduction in lift. This phenomenon occurs regardless of the aircraft's speed; when the angle of attack is too steep, even a high-speed flight can result in a stall.

Understanding this concept is crucial for pilots, as stalling can lead to a loss of control of the aircraft if not promptly managed. To recover from a stall, pilots must reduce the angle of attack, which allows airflow to reattach to the wing and regain lift. This understanding of stall dynamics is essential for safe aviation practices and contributes to the overall proficiency in aircraft handling.
