What does the "MAX" forecast period of a SIGMET typically cover?

• A. 1 hour
• B. 2 hours
• C. 4 hours
• D. 12 hours

Answer: (C)

The "MAX" forecast period of a SIGMET typically covers a duration of 4 hours. SIGMETs, or Significant Meteorological Information reports, are used to provide information about significant weather phenomena that may affect the safety of aircraft operations. This maximum forecast period is important for pilots as it gives them a clear indication of how long they can anticipate the conditions described in the SIGMET to persist. Any forecast period longer than 4 hours could lead to outdated information, as dynamic weather patterns can evolve rapidly, impacting the accuracy of forecasts beyond this duration. The establishment of a 4-hour maximum helps ensure that pilots use timely and relevant information when planning their flights, as it aligns with the rapidly changing nature of weather conditions in aviation.
