← ScienceWhich 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.
