When must the wing anti-ice system be on?

• A. When airspeed is less than 250 KIAS
• B. During climb to altitude
• C. When in icing conditions and airspeed is less than 230 KIAS
• D. When any warning light is illuminated

Answer: (C)

The wing anti-ice system must be on when the aircraft is in icing conditions and the airspeed is less than 230 KIAS because, in such conditions, the risk of ice accumulation on the wings significantly increases. Ice buildup can adversely affect the aircraft's lift and control, leading to potentially dangerous situations. Activating the wing anti-ice system helps prevent ice from forming, ensuring safe flight operations. This requirement to activate the anti-ice system under these specific conditions is emphasized in aircraft operating procedures and safety protocols. By monitoring both the environmental icing conditions and the specific airspeed limit, pilots can take proactive steps to maintain the performance and safety of the aircraft.
