Your favorite flight-planning website might conveniently calculate times and fuel burns at a most favorable altitude, but there are times when it’s likely to be dead wrong.
Forecast-Wind Follies
If I were crowned king, my first decree would be to abolish the official winds and temperatures aloft forecast, also known as the FBWinds. Its an outdated product thats fraught with problems. The problems get compounded when pilots unknowingly misuse the forecast.
Key Takeaways:
- The official FBWinds (winds and temperatures aloft) forecast, commonly used in flight planning, is an outdated, automated product generated without human oversight or amendment criteria.
- Its primary limitations include poor spatial resolution due to widely spaced forecast stations and limited vertical data, as well as inadequate temporal resolution where forecasts are only truly valid at specific times within their "for use" period.
- These inaccuracies can lead to significant errors in fuel, time, and safety planning (e.g., icing potential), especially during dynamic weather, prompting pilots to understand its flaws and consider more granular tools like Skew-T diagrams for better accuracy.
