What is an effect of ongoing increased angle of attack leading to airflow disruption?

Ongoing increased angle of attack leads to airflow disruption primarily resulting in a wing stall. As the angle of attack is raised beyond a certain critical point, the airflow begins to separate from the wing's upper surface, leading to a significant loss of lift. This stall condition can cause the aircraft to lose altitude and control if not promptly addressed. The airflow disruption means that the smooth, laminar flow over the wing is interrupted, which is essential for maintaining lift.

In contrast, enhanced fuel efficiency and improved lift generation are not effects of a stall; in fact, they are associated with optimal flight conditions. Decreased drag is also an inaccurate outcome, as stall is typically accompanied by increased drag due to turbulent airflow. Therefore, understanding the relationship between angle of attack and stall is crucial for maintaining safe and efficient flight operations.
