Within what altitude range is wind not forecast according to FD codes?

• A. 2500 feet
• B. 1000 feet
• C. 1500 feet
• D. 2000 feet

Answer: (C)

Wind is not forecast below the altitude of 1,500 feet according to FAA Terminal Aerodrome Forecast (TAF) codes. This standard is in place because winds at lower altitudes can be too variable and influenced by factors like terrain and temperature changes, making them more difficult to reliably predict. The 1,500-foot threshold is significant because it delineates the transitional area between surface conditions and upper atmospheric winds, which are generally more stable and consistent. Therefore, while surface winds may be observed, forecasts provide more reliable information about wind patterns starting from greater heights, where more systematic and predictable behaviors can be ascertained from meteorological data. Being familiar with this altitude limit is essential for pilots and meteorologists, as it directly impacts flight operations, including takeoff and landing procedures, where understanding wind conditions can influence safety and performance.
