What is the main difference between a METAR and a TAF?

• A. METAR provides weather forecasts, while TAF provides actual observations
• B. METAR provides actual weather observations, while TAF provides weather forecasts
• C. Both provide forecasts but for different periods
• D. METAR is always updated every hour, TAF is not

Answer: (B)

The main distinction between METAR and TAF lies in their functions regarding weather information. METAR reports provide actual weather observations, reflecting current conditions at an airport or aerodrome. This includes real-time data such as temperature, visibility, wind speed and direction, and cloud cover. It is crucial for pilots and aviation professionals because it offers a snapshot of the immediate weather conditions affecting flight operations. In contrast, TAFs are specifically designed to provide weather forecasts for a specified period, generally covering a 24 or 30-hour timeframe. These forecasts give an expectation of what the weather will be like in the future, including conditions like visibility, wind, and expected significant weather phenomena. Understanding this difference is vital for interpreting aviation weather reports accurately and making informed decisions related to flight safety and planning. The other choices do not accurately convey the definitions and functions of METARs and TAFs, which is central to understanding their use in aviation.
