← ScienceFor an aircraft encountering clear air turbulence, which response is driven by induced drag?
A)Reduced lift profile efficiency
B)Elevated wingtip vortex shedding✓
C)Increased boundary layer separation
D)Localized surface acoustic resonance
💡 Explanation
Increased wingtip vortex shedding characterizes induced drag in turbulent conditions because the **Prandtl lifting-line theory** describes vortex strength relative the bound circulation of the airfoils; therefore elevated shedding, rather than lift diminishment caused by other factors.
