← TechnologyWhich risk increases when a pilot over-controls cyclic input during helicopter autorotation?
A)Blade stall and loss lift✓
B)Engine overspeed and fuel cutoff
C)Transmission seizure and power loss
D)Tail rotor reversal thrust increase
💡 Explanation
Blade stall risk increases, due to the dissymmetry that occurs during autorotation because cyclic input aggressively changes blade pitch. This induces a retreating blade stall, rather than maintaining balanced lift, therefore resulting in altitude or control loss within the effective rotor disk.
