What do initials TAF stand for in aviation weather?

The initials TAF stand for Terminal Aerodrome Forecast in aviation weather terminology. A TAF is a weather forecast specifically designed for the needs of pilots and air traffic controllers at an airport. It provides critical information related to expected weather conditions at the airport for a specified period, typically 24 or 30 hours. This includes data on wind direction and speed, visibility, precipitation, clouds, and significant weather changes, all of which are vital for flight planning and safety.

Understanding TAFs is essential for pilots because the forecast helps them make informed decisions about takeoff and landing, ensuring safety during flight operations. The specific focus on a terminal area distinguishes TAFs from other weather reports, such as METARs, which provide current weather observations at an airport.
