Wind speed / direction FMS vs. Map Mode in the MD11

[Guest TSE]

Folks,Anybody else having the issue that the wind direction and speed displayed in the FMS differs from what is displayed in the cockpit while in Map Mode ?My direction offset is up to 30 degrees between the FMS and Map Mode with the FMS displaying the more accurate data.Using wind smoothing in FSUIPC plus ASV 6.5ThanksJoerg

Just a guess, the MCDU PROG page displays a moving average?

The MCDU PROGRESS page displays TRUE bearingThe ND displays MAG bearing

Thanks a lot MichaelYour answer just provided the solution to the riddle why I always see a wind direction variation compared to what AsV is reporting.Plus it is clear now why the variation is bigger on the North Atlantic and over Canada than currently over the Pacific...I can stop trying to tweak FSUIPC and AsV now :-)ThanksJoerg
