← TechnologyWhich undesired effect occurs when a helicopter's cyclic control aggressively commands forward flight?
A)Dynamic roll-over✓
B)Compressibility stall
C)Ground resonance emerges
D)Engine over-torquing occurs
💡 Explanation
Dynamic roll-over is a risk because the differential lift causes sideways thrust while landing gear friction prevents lateral movement, therefore the helicopter rolls, rather than translating as intended; compressibility stall affects high speed flight.
