How do pilots use METAR and TAF in flight planning to anticipate weather?

• A. TAF provides weather observations; METAR provides forecast data.
• B. METAR provides current conditions; TAF provides forecast conditions; together inform route selection and altitude planning.
• C. METAR provides only altitude data.
• D. TAF is used for ground handling only.

Answer: (B)

Pilots use METAR and TAF together to anticipate weather by combining what is happening now with what is expected to happen. METARs provide current conditions at airports—wind, visibility, present weather, cloud cover, temperature/dew point, and altimeter—so you know the actual weather at departure, destination, and other critical points. TAFs offer forecast conditions for the same areas over the next 24 to 30 hours, including expected winds, visibility, sky conditions, and potential weather changes. By comparing the current METARs with the TAF forecasts, a flight crew can decide on route choices and altitudes that avoid adverse weather, plan for possible holds or diversions, and ensure safe approaches and landings. This proactive use helps determine whether to expect worse conditions at arrival or en route and adjust plans accordingly.
