If Ice Detection System annunciates ICE, what action is required for wing anti-ice during flight?

• A. Wing anti-ice ON
• B. Wing anti-ice OFF
• C. Do nothing
• D. Check with maintenance

Answer: (A)

ICE means icing conditions are present and the wing leading edges need protection. Turning the wing anti-ice ON uses heat to prevent ice from forming on the wing, preserving lift and maintaining safe stall margins during flight. Leaving it OFF or doing nothing can allow ice to build up, degrading performance and controllability. Checking with maintenance isn’t the immediate action for this annunciation; the correct step is to activate wing anti-ice and continue monitoring the icing conditions.
