Which weather products are used for planning according to the AIM?

• A. METARs and TAFs for current and forecast weather, winds aloft, area forecasts, pireps, NOTAMs, and other aviation weather products.
• B. METARs and TAFs only.
• C. Winds aloft only.
• D. Area forecasts only.

Answer: (A)

Planning a flight according to the AIM relies on a broad set of weather products that cover current conditions, forecast trends, and notices that can affect routing and safety. METARs give the current surface weather, while TAFs provide the forecast for the area around the airports you’ll use. Winds aloft show expected wind speeds and directions at different flight levels, which helps with altitude selection, fuel planning, and en route performance. Area forecasts summarize the weather situation over a region to give you a general sense of what to expect on a larger scale. PIREPs provide real-time, on‑the‑ground or in-flight observations from pilots along your route, adding ground-truth detail to the forecast. NOTAMs alert you to weather-related hazards or temporary changes that could impact your flight, such as runway conditions or radar outages. Other aviation weather products round out the picture, giving you a complete planning picture rather than relying on a single source.
