How many miles does a TAF extend around an airport?

The Terminal Aerodrome Forecast (TAF) extends a radius of 5 statute miles around an airport. TAFs provide forecast information necessary for flight operations, particularly in the terminal area. The 5 statute mile radius is specifically designed to cover the area where pilots need weather information that could impact their approach, departure, and situational awareness during flight operations close to the airport.

In the context of aviation operations, this range allows for sufficient lead time for pilots to be aware of weather conditions that could affect flight safety and decision-making as they prepare for landing or takeoff. Understanding the correct radius of the TAF is essential for pilots when planning their flights and assessing weather-related risks in the vicinity of their operational airports.
