How do stall strips function?

• A. By increasing airflow at the trailing edge
• B. By creating turbulent airflow at the leading edge
• C. By reducing lift coefficient during approach
• D. By promoting clean stall characteristics

Answer: (B)

Stall strips function by creating turbulent airflow at the leading edge of the wing. This turbulence helps to maintain attached airflow over the wing at higher angles of attack, which is critical for delaying the stall. By introducing turbulence, stall strips can also contribute to smoother airflow over the wing surface, enhancing the control and predictability of the stall characteristics. In doing so, they ensure that the wing reaches its critical angle of attack in a more controlled manner, providing pilots with better handling and warnings related to imminent stalls. This can significantly improve safety during flight, particularly during critical phases such as takeoff and landing. The design and placement of stall strips are therefore essential in aircraft aerodynamic performance, making option B the correct answer.
