- Deep stalls, also known as super stalls, are a critical aerodynamic condition that can occur in certain aircraft configurations1. This phenomenon arises when the aircraft’s angle of attack (AOA) is too high, causing the airflow over the wing to disrupt the airflow over the horizontal stabilizer1. At the critical angle of attack, the airflow separates from the upper surface of the wing, resulting in a stall2.

This phenomenon arises when the aircraft’s angle of attack (AOA) is too high, causing the airflow over the wing to disrupt the airflow over horizontal stabilizer.aviationthrust.com/super-stall-understanding-critica…As the angle of attack of any aerofoil section is increased, the lift will also increase up to a point known as the critical angle. At this angle of attack (typically 15° to 20° for most aerofoil sections) the airflow separates from the upper surface of the wing and this condition is known as a stall.skybrary.aero/articles/deep-stall - People also ask
