Which effect increases when exceeding the Reynolds number threshold in aircraft wing design?

A)Increase of lift coefficient instability
B)Increase of laminar boundary layer
C)Decrease in parasite drag profile
D)Increased damping from airflow attachment

💡 Explanation

Exceeding the Reynolds number leads to a shift to turbulent flow, causing increased lift coefficient instability because of boundary layer separation due to increased momentum transfer; therefore A rather than laminar flow, with smoother airflow conditions.
