tip stall

tip stall

tip stall
Wingtip stall patterns.
tip stall
When the aircraft stalls, the nose tends to drop and decrease the angle of attack. If the tips of the wing stall before the inboard section, however, one tip will invariably start to drop before the other, and as it drops, its effective angle will increase. The stall depends on the tip, and it continues to fall. The aircraft starts rolling as the opposite wing tip rises.
The stalling of the tip of an airfoil in which the remaining portion of the airfoil remains unstalled. It is an undesirable characteristic and can lead to phenomena such as pitch-up, etc.

To help reduce the likelihood of wing tip stall and adverse yaw, engineers developed differential ailerons.
Decreasing the downward aileron deflection and at the same time increasing the upward aileron deflection helps to minimize wing tip stall while at high AoA.
