We’re happy to announce new icing and turbulence forecast layers are now available on Flightradar24.com and will soon be available in our mobile apps as well. The three new layers available today display forecasted icing, in-cloud turbulence, and clear air turbulence (CAT). Users with a business subscription will find the new layers available in weather settings.
Icing forecast
The new icing layer show areas that are forecast to generate icing conditions at various altitudes during a specified time period. Icing conditions can lead to ice build up on aircraft which can be extremely dangerous.
The icing layer forecast is valid for a 3 hour period (00:00 UTC, 03:00 UTC, etc.) for the upcoming 36 hours and the forecast is refreshed every 6 hours. Forecast icing conditions may be viewed at 4000 foot intervals from 6,000 to 30,000 feet.
In-cloud turbulence forecast
Currents and water vapor in and around clouds can cause turbulence, which aircraft want to avoid. The new in-cloud turbulence layer displays those areas which are forecast to generated in-cloud turbulence. Like the icing layer, in-cloud turbulence forecasts are valid for a 3 hour period (00:00 UTC, 03:00 UTC, etc.) for the upcoming 36 hours and the forecast is refreshed every 6 hours. In-cloud turbulence forecasts are available at Flight levels FL100 (10,000 feet), FL140, FL180, FL240, and FL300.
Clear air turbulence (CAT)
Clear-air turbulence is the turbulent movement of air without visual references, like clouds. Clear air turbulence is common in and around the jet stream and in the vicinity of thunderstorms. The new forecast layer displays those areas which are forecast to generated clear air turbulence. Like the icing and in-cloud turbulence layers, clear air turbulence forecasts are valid for a 3 hour period (00:00 UTC, 03:00 UTC, etc.) for the upcoming 36 hours and the forecast is refreshed every 6 hours. In-cloud turbulence forecasts are available at Flight levels FL240 (24,000 feet), FL270, FL300, FL340, FL390, and FL450.
All three of the new forecast layers are available now on Flightradar24.com and will be available in our mobile app for iOS and Android soon. If you’d like to take advantage of these layers, please visit our subscription page to learn more about these weather layers and all of the other great features available as part of our business subscription.
