PLT067: Information on a Sigmet
What code PLT067 covers, why the FAA tests it, and how to study Information on a Sigmet before your checkride.
Interpret information on a SIGMET
What this means for your checkride
A SIGMET warns of weather hazardous to all aircraft: severe turbulence, severe icing, widespread dust or sand, or volcanic ash. A Convective SIGMET covers thunderstorm-related hazards. Each names an area and a valid time.
SIGMETs flag the weather most likely to hurt you, so the FAA tests what each type covers and how it differs from an AIRMET.
Pilots confuse AIRMET and SIGMET severity. SIGMETs are for severe, all-aircraft hazards; AIRMETs are for less-severe conditions significant mainly to lighter aircraft.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
