What is the alphabetic designator for moderate icing?

The alphabetic designator for moderate icing is AIRMET Zulu. AIRMETs (Airmen's Meteorological Information) are designed to provide in-flight weather information for pilots, alerting them to potentially hazardous conditions.

AIRMET Zulu specifically indicates conditions of moderate icing that pilots may encounter in flight. It is essential for pilots to be aware of these conditions as they can significantly affect aircraft performance and safety.

AIRMET Tango pertains to turbulence, while AIRMET Sierra addresses IFR (Instrument Flight Rules) conditions such as visibility and ceilings. SIGMETs, like SIGMET Alpha, alert pilots to hazardous weather phenomena but often cover more severe weather events rather than moderate icing. Understanding these designators helps pilots prepare adequately for their routes and navigate safely through various weather conditions.
