Why is it important for TAF to focus on forecasted weather conditions?

The focus of TAF on forecasted weather conditions is primarily important for aiding in flight planning and safety. TAFs provide critical information to pilots and airlines about expected weather conditions at an airport over a specific time frame, usually 24 to 30 hours. This information enables flight crews to make informed decisions regarding routing, altitude, and operational strategies, which ultimately enhances safety.

For instance, if a TAF indicates the likelihood of thunderstorms or severe turbulence, pilots can alter their flight plans to avoid these hazards. Furthermore, having accurate forecasts helps airlines manage their operations more effectively, ensuring better on-time performance and heightened safety for passengers and crew alike.

While informing passengers about delays and determining crew assignments may be related to the operational impacts of weather, these aspects are secondary to the primary function of TAFs, which is to promote safe flight operations through effective weather forecasting. Reporting the previous day's weather does not serve the purpose of TAF, as these forecasts are intended to predict future conditions rather than review past events.
