What is an "AIRMET" used for?

An AIRMET is specifically designed to provide information about weather phenomena that could potentially impact flight safety, particularly for smaller aircraft. These advisories include updates on conditions such as moderate turbulence, icing, and restricted visibility that may not be severe enough to warrant a SIGMET, which is aimed at larger aircraft.

While turbulence levels, volcanic activity, and airspace restrictions are all crucial elements in aviation safety, they fall under different reporting categories. For instance, volcanic activity would typically be highlighted in a SIGMET, while airspace restrictions are conveyed through NOTAMs (Notices to Airmen). The AIRMET’s primary focus on less severe but still significant weather conditions makes it a vital tool for pilots who are operating in potentially hazardous environments, ensuring they have the necessary information to maintain safety during their flights.
