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

The term "stall" in aviation specifically refers to a condition where airflow over the wings is disrupted, leading to a loss of lift. This phenomenon typically occurs when the angle of attack exceeds a critical limit, causing the smooth airflow over the wings to separate and resulting in a significant reduction in lift. When an aircraft stalls, it can no longer maintain the altitude or flight path, which may require immediate corrective actions from the pilots to recover control and regain lift.

Understanding a stall is crucial for pilots, as handling this situation effectively is vital for flight safety. Pilots are trained to recognize the signs of an imminent stall, such as changes in aircraft behavior and handling, and to perform stall recovery techniques when necessary. The other options do not accurately represent the definition of a stall and instead describe different aviation concepts or maneuvers.
