What is one method to delay stall at the wing tip?

Creating a lower angle of incidence at the wing tip is a method to delay stall because it reduces the lift generated at that part of the wing. When the angle of incidence is decreased, the airflow over the wing tip remains attached longer, even as the overall angle of attack increases. This helps prevent the wing tip from reaching its critical angle of attack, where stall would occur.

By maintaining the airflow over the wing tip, pilots can achieve improved stall characteristics, leading to more stable and controllable flight conditions. This is particularly important in preventing stall at the tips, which can lead to asymmetric lift and potential control issues.

In contrast, increasing the wing's weight or adjusting turbulence levels does not effectively address the stall characteristics at the wing tip. Shortening the wingspan may actually create more stall issues by increasing the load on the remaining wing sections, thereby decreasing overall lift efficiency.
