Which statement best describes the roles of METAR/TAF, SIGMET/AIRMET, NOTAM, radar, and satellite in weather interpretation?

• A. NOTAM informs about weather restrictions.
• B. METAR/TAF provide current and forecast conditions; SIGMET/AIRMET warn hazardous weather; NOTAM informs restrictions; radar shows precipitation; satellites depict cloud and storm development.
• C. Radar images replace the need for METAR.
• D. METAR/TAF provide weather forecasts only.

Answer: (B)

In weather interpretation for flight, each tool provides a different piece of the bigger picture, and together they give you current conditions, short-term forecasts, hazards, and the operational limits you need to plan around. METARs and TAFs are the foundation for this picture: METARs give you the actual weather at specific airports right now (wind, visibility, weather phenomena, sky condition, temperature, and altimeter), while TAFs forecast those conditions for the next 24 hours or so. This pair lets you judge what you’re likely to encounter on departure, en route, and at destination in the near term. Hazard awareness comes from SIGMETs and AIRMETs. SIGMETs warn of significant weather that could be hazardous to all aircraft, such as severe thunderstorms, severe icing, severe turbulence, widespread dust or sandstorms, or volcanic ash. AIRMETs cover less intense but still potentially hazardous conditions, like moderate turbulence or icing, mountain obscuration, or strong winds. These advisories help you decide whether to fly, reroute, or plan timing around areas of adverse weather. NOTAMs deliver notices about temporary changes to aeronautical facilities or services. They aren’t weather products themselves, but they can include weather-related restrictions (for example, runway closures or navigation aid outages). They inform you about any operational limitations that could affect your flight. Radar shows precipitation and its movement in real time, helping you see where rain or storms are occurring nearby and how they’re evolving. Satellites provide a broader view of cloud cover, storm development, and large-scale weather patterns, including infrared and visible imagery that reveals cloud tops, temperature, moisture patterns, and the growth or decay of weather systems beyond radar range. Taken together, this set of tools gives you a complete, practical picture: current and forecast conditions from METAR/TAF, hazard warnings from SIGMET/AIRMET, operational restrictions from NOTAM, real-time precipitation from radar, and larger-scale and developing weather from satellite imagery. The other options either constrain the roles too narrowly or suggest one tool can replace another, which isn’t the case.
