Crosswind & prevailing wind color depiction on Meteogram view

There’s no doubt that wind is the leading cause of weather-related aircraft accidents.  Even so, strong crosswinds can make for a challenging landing even for the most seasoned pilot. So to help alert you to nasty wind conditions expected at an airport over the next three days, WeatherSpork version 4.3.5 has enhanced the wind Meteogram by adding “traffic light” colors (red, yellow and green) to the time-series wind graph depicted on the Meteogram view.

For an airport, the observed or expected prevailing wind (shown above) is plotted as a continuous line and color coded by wind speed using the following colors:

  • Green – 0 to 10 knots.
  • Yellow – 11 to 20 knots.
  • Red – greater than 21 knots.

The crosswind component is depicted as a color-filled graph overlaid on the same time-series depiction. Crosswinds are evaluated by determining the best opportunity runway based on the observed or forecast winds at the surface using the following colors:

  • Green – 0 to 10 knots.
  • Yellow – 11 to 15 knots.
  • Red – greater than 16 knots.

So the next time you go flying be sure to check the WeatherSpork Meteogram to determine if a challenging takeoff or landing are in your future.
