What is a G Airmet?

A G – AIRMET is a graphical advisory of weather that may be hazardous to aircraft, but are less severe than SIGMETs. They are only valid at specific time “snapshots”. Forecasters create graphical objects depicting the areas and attributes of AIRMET hazards, which are distributed in BUFR file format.

What does Metar stand for?

METAR is the international standard code format for hourly surface weather observations which is analogous to the SA coding currently used in the US. The acronym roughly translates from French as Aviation Routine Weather Report.

How long is an Airmet valid for?

AIRMETs are valid for six hours. NOTE: The definition has changed and no longer says “light aircraft”; AIRMETs are intended for all aircraft. AIRMET TANGO (Turbulence) moderate turbulence, sustained surface winds of 30 knots or greater, and/or non convective low−level wind shear.
