Which risk increases adjacent to an aircraft wing undergoing turbulent flow?

A)Increased skin friction drag coefficient
B)Premature laminar flow re-establishment
C)Reduced adverse pressure gradient strength
D)Boundary layer separation and stall

💡 Explanation

Boundary layer separation and stall risk grows with turbulence because it introduces chaotic mixing and elevated momentum exchange. This mixing energizes the slower boundary layer, but that energy is quickly lost; therefore separation occurs because of increased momentum transfer rather than reduced pressure.
