4.10.10 SIGMETs and AIRMETs (SIG/AIR)

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 in the U.S. Elsewhere, updates are made as they are issued.
