4.4.10 SIGMETs and AIRMETs
SIGMETs (SIGnificant METeorological Information) and AIRMETs
(AIRmen’s METeorological Information) are broadcast for potentially hazardous
weather considered of importance to aircraft. A Convective SIGMET is issued
for hazardous convective weather. A localized SIGMET is a significant weather
condition occurring at a localized geographical position.
When enabled, SIGMET/AIRMETs advise the pilot of potentially hazardous
weather, other than convective activity, to all aircraft. The advisory covers an
area of at least 3,000 square miles at any one time. SIGMET/AIRMET data
covers icing, turbulence, dust, and volcanic ash as issued by the National
Weather Service. The update rate is every 12 minutes.
