Which AIRMET code is associated with icing conditions?

The AIRMET code associated with icing conditions is "Zulu." This designation indicates moderate icing, which is important information for pilots who need to be aware of the potential for ice accumulation on their aircraft. Icing can significantly affect an aircraft's performance and safety, making it critical for pilots to receive timely updates about these conditions.

The other AIRMET codes serve different purposes: "Sierra" relates to IFR conditions and visibility; "Tango" pertains to turbulence; and "Echo" addresses effects from volcanic ash. Each code provides crucial information, but Zulu is specifically focused on the risks posed by icing conditions, making it the correct choice in this context.
