← TechnologyWhat happens when an aircraft's wing leading-edge de-icing system fails?
A)Lift decreases due to ice accretion✓
B)Engine thrust significantly increases initially
C)Control surface effectiveness improves
D)Drag reduces minimizing stall effects
💡 Explanation
Lift is significantly impacted when ice accumulates; the system's failure activates **ice accretion**, massively distorting the airfoil shape because the boundary layer is disrupted, therefore stall speed abruptly increases, rather than being preventable by thrust or control surface adjustments.
