What is the primary purpose of a TAF (Aerodrome Forecast)?

The primary purpose of a TAF, or Terminal Aerodrome Forecast, is to provide specific weather forecasts for an aerodrome over a designated period, typically 24 to 30 hours. TAFs are crucial for flight operations, as they offer pilots and air traffic controllers detailed information about expected weather conditions at the aerodrome, helping them make informed decisions regarding flight safety and operations.

A TAF typically includes predictions on elements such as wind direction and speed, visibility, significant weather phenomena, and cloud cover. This information is vital for takeoff and landing phases of flight, which are heavily influenced by local weather conditions. By focusing specifically on the airport or aerodrome, TAFs serve the aviation community effectively, ensuring that users have access to tailored weather forecasts that directly impact flight operations. This makes option B the correct answer.
