Which statement best describes AIRMET?

Which statement best describes AIRMET?

• A. Provides advisories for less severe weather over broad areas
• B. Warnings of significant weather hazards
• C. Observations only for major airports
• D. Not relevant for ATC

Answer: (A)

AIRMETs are advisory messages about weather phenomena that are not as severe as those in SIGMETs but can still affect flight safety. They cover broad geographic areas to help pilots and air traffic controllers plan for moderate conditions, especially for smaller aircraft that may be more impacted by lighter but widespread weather issues. This is why the best description is that they provide advisories for less severe weather over broad areas. They aren’t warnings of significant hazards (that’s the role of SIGMETs), they aren’t observations limited to major airports (AIRMETs apply over large regions, not just at specific airports), and they are indeed relevant for ATC and flight operations.
