What is the primary purpose of a TAF?

The primary purpose of a Terminal Aerodrome Forecast (TAF) is to provide a weather forecast specifically for aircraft operations at an airport. TAFs are crucial for pilots and air traffic control as they offer essential information on expected weather conditions, such as wind direction and speed, visibility, significant weather phenomena, and cloud cover over a specified time period. This helps in decision-making for flight planning and operational safety.

While there are other types of reports and announcements that cover past weather, regulatory changes, and travel delays, these do not align with the function of TAFs. TAFs focus on forecasting future conditions to ensure safe and efficient flights, unlike reports that are historical in nature or aimed at informing travelers about disruptions.
