Which statement correctly describes the wing anti-icing switch location and system?

• A. The wing anti-icing switch is located on the overhead switch panel and uses bleed air
• B. The wing anti-icing switch is located on the center console and uses electrical power
• C. The wing anti-icing switch is located on the instrument panel and uses hydraulic pressure
• D. The wing anti-icing switch is located on the cabin panel and uses engine oil

Answer: (A)

Wing anti-icing on this airplane uses bleed air to heat the wing leading edges and prevent ice buildup. The control switch for this system is located on the overhead switch panel for quick access in icing conditions, and when selected, engine bleed air is routed through anti-ice valves to the wing leading edges. This pneumatic heating arrangement is why the system is described as bleed-air, not electrical, hydraulic, or oil-based. The other locations and media wouldn’t apply to how the wing anti-ice is implemented on the Beechjet 400A.
