If you get a standard briefing through Lockheed Martin Flight Service or via DUATS, you will be provided the official winds and temperatures aloft forecast also known as the FBWinds. Additionally, many of the most popular online flight planners also utilize this official forecast in their flight planning calculations and briefings. What most pilots don’t appreciate is that the official FBWinds has a rather coarse temporal and spatial resolution which can lead to significant errors in the temperature and/or wind forecast provided. In this workshop, we will look at how the passage of a strong cold front can greatly impact the accuracy of the FBWinds temperature forecast leading the pilot to believe the freezing level will be several thousand feet higher than what will actually occur.
