Which statement is true about AIRMETs?

• A. AIRMETs are short-term forecasts for high-altitude jet streams.
• B. AIRMET alerts pilots to hazardous weather for small aircraft operations, such as moderate turbulence, low-level wind shear, icing, or IFR conditions.
• C. AIRMETs provide long-term climate forecasts.
• D. AIRMETs are post-flight reports.

Answer: (C)

AIRMETs are weather advisories aimed at pilots of small aircraft, warning about hazards that can affect general aviation and VFR flight. They focus on conditions that are significant but not extreme, such as moderate turbulence, low-level wind shear, icing, or IFR conditions, and they’re issued for six-hour periods over specific regions. This makes the statement describing AIRMETs as alerts for small aircraft operations covering hazards like moderate turbulence, low-level wind shear, icing, or IFR conditions the true one. They aren’t long-term climate forecasts, they aren’t post-flight reports, and they’re not specifically about high-altitude jet streams; those roles belong to other aviation weather products like SIGMETs and Convective SIGMETs.
