What is the primary function of a TAF?

The primary function of a Terminal Aerodrome Forecast (TAF) is to forecast future weather conditions, particularly for aviation purposes. TAFs are designed to provide a detailed weather forecast for a specific aerodrome or airport over specific periods, typically covering a 24 or 30-hour timeframe, with updates made every six hours. They include critical information such as expected wind speeds and directions, visibility, significant weather phenomena (like precipitation), and cloud cover.

This focus on forecasting is essential for pilots and air traffic controllers as it aids in planning flights, making decisions on flight paths, and ensuring safety. By providing predictive information tailored for airport operations, TAFs enable effective risk management in aviation by allowing for proactive adjustments to flight plans based on anticipated weather conditions.
