Default RE: Stall Question

Textbook:

A certain amount of air turbulence occurs on the surface of most aircraft wings, regardless of the shape and sizeof the wing. As air moves across an airfoil, it is changed by the frictional force between it and the airfoil's surface from a laminar (smooth) flow at the forward area to a more turbulent flow toward the trailing edge. The 'perfect" wing would demonstrate laminar airflow across the entire surface of the wing, with no sign of turbulence. This turbulence affects flying performance by increasing aerodynamic drag and fuel consumption.

Just because the flow is not laminar does not mean that the wing stalls. That was my point.
