How often are TAFs typically issued?

TAFs, or Terminal Aerodrome Forecasts, are typically issued every 6 hours. This frequency allows for timely updates reflecting changing weather conditions that can affect aviation safety and operations at specific airports. Each TAF covers a specific period, usually 24 or 30 hours, providing forecasts on expected weather phenomena such as wind, visibility, and precipitation.

Issuing TAFs every 6 hours ensures that pilots and airlines have the most current weather information available, which is crucial for flight planning, departures, and arrivals. This frequency balances the need for up-to-date data while also considering the resource requirements of meteorological services. Therefore, the option that states TAFs are issued every 6 hours accurately reflects the standard practice in the aviation industry.
