Which risk increases when helicopter rotor downwash induces ground turbulence?

A)Engine flameout due to fuel starvation
B)Reduced braking effectiveness while landing
C)Increased structural fatigue crack propagation
D)Tail rotor stall due to vortex interference

💡 Explanation

Increased ground turbulence impacts a helicopter because random pressure fluctuations accelerate fatigue crack propagation, rather than causing engine failure or changing aerodynamics directly. Turbulent airflow produces stochastic loading; therefore, the primary risk becomes accelerated fatigue failures, rather than immediate control losses via stall.
