Thanks!
If you have a an FMS/GPS, one of your screens will tell actual winds aloft.
In order to calculate GS in advance for flight planning, use the winds aloft forecast.
If you need to get a GS in flight, set a fixed TAS then use a timer between two nav waypoints (VORs). Plug distance and time into the E6B.
Or ask ATC...their radar shows your GS.
