Aircraft ... in general, ... are not certified to fly with any contamination [(e.g. possible contaminants: frost, squashed bugs, anti-icing fluids, etc.)] on the lift and control surfaces. However, ... small amounts of surface contamination usually result in roughness. This causes local changes in the pressure gradient in the boundary layer and can cause turbulence in a laminar flow boundary layer or complete flow separation from the surface. 3, record 1, English, - laminar%20boundary%20layer
Record number: 1, Textual support number: 2 CONT
Above a surface, a laminar layer will develop and fluid velocity will increase with distance from the surface, but not indefinitely. At some point, flow will become turbulent, with the laminar sublayer separating the turbulent layer from the surface. In the real world, most laminar boundary layers are extremely thin (order of 1 mm), but can be of biological importance, for example, next to plant leaves or as invertebrate refuges in streams. 5, record 1, English, - laminar%20boundary%20layer
