Which phenomenon causes increased drag on a subsonic aircraft wing encountering clear-air turbulence?

💡 Explanation

The instability created by clear-air turbulence causes a disturbance in the airflow, resulting in boundary layer separation; this detachment increases the pressure drag because the pressure never fully recovers. Therefore, stall occurs rather than maintaining laminar flow or exceeding the critical Mach.
