What is the angle of attack during post-stall gyrations phase?

• A. Below 10 degrees
• B. Around 15 degrees
• C. Above 18 degrees
• D. Consistently fluctuating

Answer: (C)

During the post-stall gyrations phase, the angle of attack typically exceeds 18 degrees. This phase occurs after a stall, where the aircraft is unable to maintain controlled flight due to excessive angle of attack. In this condition, the airflow over the wings is disrupted, leading to multiple uncontrolled rotational movements of the aircraft. As a result, the angle of attack during this phase significantly exceeds the critical angle of attack—the point at which stalls occur. When an aircraft experiences post-stall gyrations, pilots face a series of rapid changes in aerodynamic forces, and thus the angle of attack remains well above 18 degrees, contributing to the destabilized and uncontrolled flight characteristics. Understanding this phase and the corresponding angle of attack is crucial for pilots and aviation professionals in recognizing stall recovery techniques and managing aircraft performance in compromised flight conditions.
