When a TAF is issued, where does it apply?

A Terminal Aerodrome Forecast (TAF) provides weather information that is specifically intended for the area around an airport. The forecast typically covers a 5 statute mile radius from the center of the airport and extends upwards to various altitudes as needed for aviation operations. This radius is significant because it ensures that pilots and airline operations can anticipate and prepare for weather conditions that could impact takeoff, landing, and other critical phases of flight around that airport.

The TAF is specifically designed to give detailed weather forecasts that are pertinent to a specific airport rather than broader airspace or flight routes. Therefore, the focus on a 5 statute mile area makes it an essential tool for pilots in managing their operations safely and effectively while considering the vicinity of the airport's operational environment.
