SIGMET is an acronym for which of the following?

• A. Significant Meteorological Information
• B. Significant Military Information
• C. Signal Meteorological Information
• D. Special Meteorology Information

Answer: (A)

SIGMET stands for Significant Meteorological Information. In aviation, this is an urgent weather advisory issued by meteorological authorities to warn pilots and air traffic controllers about significant weather phenomena that could affect flight safety. These warnings cover weather hazards that may not be related to thunderstorms (which have their own Convective SIGMET) but still pose real risks, such as severe icing, severe turbulence not associated with thunderstorms, dust or sand storms reducing visibility, and volcanic ash. The other options would not reflect the standard aviation term, since SIGMET specifically denotes meteorological information of significance to flight safety, not military, signal, or special information.
