Which weather product provides a forecast of weather conditions for a specific airport over a 24 to 30-hour period?

• A. METAR
• B. SIGMET
• C. TAF
• D. AIRMET

Answer: (C)

Think about the purpose and the time horizon of aviation weather products. The forecast you want is for a specific airport and covers roughly a day into the future, describing expected winds, visibility, weather phenomena, sky condition, and how these elements may change over time. That is exactly what a Terminal Aerodrome Forecast provides: an airport-specific forecast for about 24 to 30 hours, including changes such as tempo or becoming groups that indicate temporary fluctuations and upcoming conditions. METAR, by contrast, is a current weather observation for an airport, updated regularly but not a forecast. SIGMET and AIRMET are advisory bulletins about significant weather hazards, either en route or region-wide, not the detailed airport-specific forecast for the next day. Hence, the forecast product that matches the requirement is the Terminal Aerodrome Forecast.
