During what flight condition is stall identified?

Stall is identified when the angle of attack exceeds critical limits. The critical angle of attack is the maximum angle at which the wings can generate sufficient lift before airflow begins to separate from the airfoil, leading to a significant loss of lift. When the angle of attack increases beyond this critical threshold, the wings cannot sustain their lift performance, resulting in a stall condition.

Understanding the dynamics of stall is crucial for pilots, as it emphasizes the importance of maintaining an appropriate angle of attack during flight. This knowledge helps in preventing situations that could lead to loss of control, particularly during maneuvers that require changes in pitch or when operating at slower airspeeds.

In other scenarios, such as high-speed maneuvers or turbulence, while the aircraft may encounter challenging flight conditions, these do not inherently signify a stall unless the angle of attack is also exceeded. Similarly, descending at a stable rate does not necessarily lead to a stall unless the flight path and angle of the wings create a situation where the critical angle is breached.
