Which of the following are contained in hazardous inflight weather advisories?

• A. Thunderstorms, AIRMETS, and SIGMETS
• B. AIRMETS, SIGMETS, and Convective SIGMETS
• C. Tornadoes, Convective SIGMETs, and hurricanes
• D. Icing, turbulence, and Center Weather Advisories ( CWA )

Answer: (B)

Hazardous inflight weather advisories come from three main products: AIRMETs, SIGMETs, and Convective SIGMETs. AIRMETs warn about weather that is significant to safety but less intense, such as moderate icing, moderate turbulence, or instrument meteorological conditions over a broad area. SIGMETs alert to more significant weather that could affect safety for all aircraft, including severe icing, severe or extreme turbulence, dust or sand storms, and volcanic ash. Convective SIGMETs address active convective weather, specifically severe thunderstorms with hazards like strong winds, large hail, and tornadoes.

This combination is the most accurate reflection of the hazardous inflight advisories because it lists the official advisory types used to convey these weather hazards to pilots en route. Center Weather Advisories exist as short-term updates, but they’re different from the three primary hazardous inflight advisory categories, and spelling out thunderstorms or other hazards without the proper convective advisory category doesn’t align with how these advisories are issued.
