What is the standard validity period for a TAF?

The standard validity period for a Terminal Aerodrome Forecast (TAF) is typically between 24 to 30 hours. TAFs are crucial for aviation as they provide weather forecasts for specific airports and are used by pilots and meteorologists to anticipate weather conditions during takeoff, landing, and in-flight operations. The validity period allows for the prediction of weather trends and helps in flight planning. This forecast period is longer than other routine weather reports, such as METARs, which are updated more frequently, making TAFs essential for long-term operational planning in aviation.
