Stall (flight)

In aerodynamics, a stall is a condition in which an excessive angle of attack causes loss of lift due to disruption of airflow.

An aircraft in flight is usually not pointed directly into the oncoming airflow. The angle (when viewed from the side of the aircraft) between the airflow and the wing is called the angle of attack (not to be confused with the pitch angle). If a pilot allows the angle of attack to become too large, the airflow will be unable to remain attached to the wing and it will begin to separate from the wing, creating a dramatic loss of lift. This condition is known as a stall.

Stall recovery usually involves reducing the angle of attack to "break" the stall, and adding power to begin a climb.
