Revision as of 08:40, 19 October 2007 by Miltopia (talk | contribs) (remove broken link)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)An AIRMET, or Airmen's Meteorological Information, is a weather advisory issued by a meteorological watch office for aircraft that is potentially hazardous to low-level aircraft /aircraft with limited capability. Compared to SIGMETs, AIRMETs cover less severe weather: moderate turbulence and icing, surface winds of 30 knots, or widespread restricted visibility.
AIRMETs are broadcast on the ATIS at ATC facilities, and are referred to as Weather Advisories. AIRMETs are valid for six hours.
There are three types of AIRMET, all identified by a phonetic letter: S (Sierra), T (Tango), and Z (Zulu). Sierra describes IFR conditions or mountain obscurations. Tango describes turbulence, high winds, or nonconvective Low Level Wind Shear. Zulu deals with icing and freezing levels.
