Practice question

What causes an aerodynamic stall on an aircraft wing?

  1. The angle of attack becomes too steep, causing the airflow to separate from the upper surface of the wing and destroy lift
  2. The aircraft's engines stop running due to fuel starvation
  3. The aircraft exceeds its maximum structural speed limit (Vne)
  4. The boundary layer air turns from turbulent to laminar flow

Answer: A — The angle of attack becomes too steep, causing the airflow to separate from the upper surface of the wing and destroy lift
