How frequently is the TAF updated?

• A. Every 4 hours
• B. Every 3 hours
• C. Once a day
• D. Every hour

Answer: (A)

The Terminal Aerodrome Forecast (TAF) is a critical component for flight planning and operational decision-making, particularly under IFR conditions. It is updated every 4 hours, which allows for the provision of relatively recent weather information that is essential to pilots and air traffic controllers. The 4-hour cycle typically provides a forecast that covers a 24-hour period, with sometimes a 30-hour forecast for specific airports. This regular interval ensures that pilots have access to the most pertinent and timely weather information for the airports they are operating in or near, which is essential for safety and effective flight planning. The 4-hour updates are necessary to capture significant changes in weather conditions that could impact flight operations.
