What part of the wing can be heated by the Wing Anti-ice?

• A. Three most outboard slats.
• B. All slats
• C. Wing tips
• D. Leading edge of entire wing

Answer: (A)

Wing anti-ice heats the wing’s leading-edge sections to prevent ice buildup, but on the A320 the heating circuit is limited to the leading edges of the three outer slats. This targets the area most exposed to icing when the wing is operating with extended slats, helping to maintain lift and stall characteristics without wasting bleed-air or risking heat damage to other wing parts. The entire leading edge and the innermost slats aren’t heated by this system, and the wing tips aren’t heated by wing anti-ice.
