Aviation Weather

Aviation weather is one of the most heavily tested areas on the FAA knowledge test — and one of the most important for pilot safety. This topic covers weather theory (how weather systems form and move), practical weather products (METARs, TAFs, AIRMETs, SIGMETs), and the specific hazards that weather poses to flight: thunderstorms, icing, turbulence, fog, and wind shear.
