Which risk increases when a subsonic aircraft exceeds its critical Reynolds number?

💡 Explanation

When the Reynolds number is exceeded, laminar flow transitions due to boundary layer instability; therefore, the risk of turbulence increases substantially because increased energy dissipation occurs, rather than the other factors happening primarily in supersonic conditions.
