1       Introduction 


This topic shows you how to view turbulence information on the map and how you can avoid turbulence when building a flight plan. 

We estimate that this will take 3 minutes to complete.


Turbulence is based on your subscription to NFP. If you don`t see the turbulence functionality described here on the map screen you don`t have the turbulence module. Contact support for more information.

The Turbulence checkbox displays turbulence information on the map. Darker lines on the map indicate higher levels of turbulence. The Flight Level drop-down list lets you specify the flight level to show the winds. Turbulence information is time-stamped on the map.

Turbulence data is only available from the Telvent weather source. You must set Win Source to TEL on FOMS 170 to use turbulence data in flight plan calculations.

View Turbulence Data on the Map

You can view turbulence data on a point on the map or for an airport. Right-click on a point on the map or an airport to view turbulence data. You must have the turbulence checkbox selected to view turbulence data on the map.

Turbulence Avoidance

Once a flight has been computed the turbulence data for the main route and all of the Altn, including reclear are shown on the flight plan.

Also, the NFP system produces a compute warning if it is unable to avoid the turbulence specified in FOMS 220.

Route Wind Profile

If the route profile chart is added in the flight package and set to “Distance Winds”, you will be able to see turbulence displayed on the chart.
