← TechnologyWhich outcome results to a twin-engine aircraft when asymmetrical thrust occurs upon landing approach?
A)Increased yaw and roll moment✓
B)Elevated stall speed threshold
C)Reduced control surface effectiveness
D)Propeller blade icing rapidly expands
💡 Explanation
Increased yaw and roll results because pilot-induced oscillation increases via adverse yaw from asymmetrical thrust at low speeds; Dutch roll, rather than benign correction actions, is activated therefore; stall margins or control effectiveness will not inherently degrade but aircraft handling does.
