business and finance aviation industryWhat is Sigmet and Airmet?
After all, both describe non-ideal weather conditions for flying. But there are important differences. AIRMETs focus on weather that may adversely affect aircraft safety in still-flyable weather. SIGMETs, which come in non-convective and convective types, focus on more severe weather conditions.
Similarly, what is in a Sigmet?
SIGMET, or Significant Meteorological Information AIM 7-1-6 , is a weather advisory that contains meteorological information concerning the safety of all aircraft. SIGMETs are issued as needed, and are valid up to four hours. SIGMETS for hurricanes and volcanic ash outside the CONUS are valid up to six hours.
- AIRMET Sierra: Mountain obscuration. Ceilings are less than 1000′ and 3 over a wide area.
- AIRMET Tango: Turbulence. Light to moderate turbulence or sustained surface winds of 30 knots.
- AIRMET Zulu: Icing. Moderate icing and freezing levels.
