Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… … Wikipedia

Wingtip stall patterns.
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.
