How do icing conditions influence limitations for engine and wing operations?

• A. They improve engine efficiency.
• B. They have no effect on limitations.
• C. They may require anti-ice/ice protection and can impose configuration or speed restrictions.
• D. They require disabling anti-ice systems.

Answer: (C)

Ice changes how air and fuel flow around the airplane, so engines and wings must be protected from ice buildup. In icing conditions, ice can block engine inlets and reduce lift on the wings, which can threaten safe operation. To counter this, crews activate engine and wing anti-ice/ice protection systems. Those conditions may also require sticking to particular configurations or speed ranges to keep performance and handling within safe limits. So icing conditions directly drive the use of anti-ice/ice protection and can impose configuration or speed restrictions. The other options don’t fit because icing does not improve efficiency, it does affect limits, and you generally don’t disable anti-ice in icing conditions.
