Where is the wing anti-ice system located on the Boeing 737?

• A. Around the trailing edge
• B. In the wing root
• C. On the wingtips
• D. Around the leading edge

Answer: (D)

Ice forms most where the air first meets the wing, so anti-ice systems heat that area to keep the airflow smooth and maintain lift. On the Boeing 737, the wing anti-ice heat is applied around the leading edge—via heated panels and ducts that warm the front of the wing. This location is critical because it directly prevents ice buildup on the surface that first encounters the airflow, keeping stall speeds and aerodynamic performance in check. Heating the trailing edge, wing root, or wingtips wouldn’t protect the key area where ice most affects lift, so the leading-edge region is the correct spot for the wing anti-ice system.
