How long is an AIRMET valid for?

• A. 2 hours
• B. 4 hours
• C. 6 hours
• D. 8 hours

Answer: (C)

An AIRMET, or Airmen's Meteorological Information, is a type of in-flight weather advisory that is issued to provide information about weather conditions that may be hazardous to aircraft but are less severe than conditions that would warrant a SIGMET. The correct duration of validity for an AIRMET is 6 hours from the time it is issued. This 6-hour period allows pilots to be informed about the potential weather impacts on their flight, giving them enough time to prepare and make informed decisions. After this period, the information may no longer be accurate or relevant, which is why it is crucial for pilots to check for updated AIRMETs as needed during their flight planning and execution.
