What does the Winds and Temperature Aloft Forecast (FB) provide?

• A. A weekly forecast for surface weather.
• B. A twice daily forecast for wind and temperature aloft over specified locations.
• C. An hourly forecast for visibility.
• D. A forecast of precipitation only.

Answer: (B)

The Winds and Temperature Aloft Forecast gives forecasted wind direction and speed and the air temperature at specific flight levels for chosen locations, and it’s issued twice daily. This information is used for planning how fast you’ll actually travel over the ground, what heading to fly to compensate for winds, and how temperature at altitude will affect air density and performance. It covers aloft layers (like 3,000 ft, 6,000 ft, etc.) rather than surface conditions.

Why this is the best choice: it accurately describes that the forecast focuses on winds and temperatures at various altitude levels for specific locations and is provided twice daily for planning purposes.

It isn’t a weekly surface weather forecast, so it doesn’t cover surface conditions. It isn’t an hourly visibility forecast, and it doesn’t focus on precipitation only.
