XM 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 to all aircraft. SIGMET/AIRMET data covers icing, turbulence, dust,
and volcanic ash as issued by the National Weather Service. The update rate is
every 12 minutes.
When enabled, the following AIRMETs are available for display:
• Icing
• Turbulence
• IFR conditions
• Mountain obscuration
• Surface winds
