What is the primary use of the TAF in aviation?

The primary use of the Terminal Aerodrome Forecast (TAF) in aviation is weather forecasting. TAF provides detailed weather predictions for specific airports, typically covering a period of up to 24 to 30 hours. These forecasts include information on wind direction and speed, visibility, significant weather events, and cloud cover. This information is crucial for pilots and flight planners to assess current conditions and anticipate how the weather will evolve during flight operations. By utilizing TAF, aviation stakeholders can make informed decisions to ensure safety, compliance with regulations, and efficient flight operations.

While flight planning may involve various weather data, including TAF, it is more accurately an application of the weather information provided, rather than the primary purpose of TAF itself. Height measurements and aircraft performance analysis are not directly related to TAF, as they focus on different aspects of aviation that do not involve forecasting weather conditions.
