How does a dispatcher use METAR and TAF in planning a flight?

• A. METAR provides current weather observations; TAF provides forecast weather. Dispatch uses METAR/TAF to assess current conditions and plan route, fuel, and alternatives.
• B. METAR provides aircraft performance data; TAF provides crew duty hours.
• C. METAR is used for NOTAMs; TAF for route restrictions.
• D. METAR and TAF determine aircraft maintenance schedule.

Answer: (A)

METAR and TAF provide weather information that is essential for flight planning. METAR gives current weather observations for an airport—wind at the surface, visibility, current weather phenomena, and cloud cover—so you know the actual conditions at departure and what you might encounter during the initial phase of the flight. TAF offers forecast weather for the same airports over the next 24 hours, including expected winds, visibility, cloud layers, and any significant weather events, with indicators for changes such as TEMPO or PROB, which signal temporary or uncertain conditions. A dispatcher uses METAR to understand the present environment and compare it to the planned departure time, and uses the TAF to anticipate how conditions may evolve along the route and at the destination. This information directly influences routing choices to avoid areas of adverse weather, the selection of alternates if forecast conditions deteriorate, and fuel planning to account for wind effects, potential holds, or delays. In short, METAR gives the current picture, and TAF provides the forecast, and together they drive route, fuel, and alternate planning.
