Ok! Now I can understand...

Thank you

No, the GS is the output of a calculation which involves the wind effect and (before that) the conversion from IAS to TAS. With nil wind, your GS will still be different to IAS.

I Know that, but in the printable Pilot log there is only the IAS and it seems that with wind calculation the GS is derived from IAS, subtracting or adding the wind component.
So... if you want to show the there are no calculation cause you set up 000/00 the IAS and GS (in the printable Pilot Log) should be the same.

mmm... I tried again... I can see 000/00 but... why is there a GS calculated? it should be same as IAS

I can confirm that setting 0/0 for all legs gives 0/0 in the PLOG and therefore nil wind calculations. This was tested on the latest release of SkyDemon Plan for PC.

Any suggstions?

mmm... I set up 0/0 for all legs, but when I go to the print center I've all the same wind caluculations.

Thank you!

Select "Weather" then "Enroute Conditions". In the box labelled "Route Legs" Ensure that all legs are highlighted then under "Conditions" enter "0/0".
