Hi all, Just wondering how the Transatlantic winds are calculated, because I noticed ASV is based around weather stations.Also, going westbound and eastbound, with vatsim weather or without, causes alot of cruise speed problems with the PMDG 744. There are two issues:1) Winds changing direction causing massive speed limit changes, from .86 cruise to stall speed. I have put a wind smooth in FSUIPC of 1 knt /sec but I still havent worked out a satisfactory setting.2) Speed loss. This is regardless of wind direction, happens with tailwinds or headwinds. Without a noticable change in weather conditions, sometimes the aircraft loses speed, again from .86 cruise to stall. I cannot notice any weather changes when this happens, only solution is to descend until problem dissappears.I have done 10 transatlantic flights now and everytime my engines are set to CON just to deal with these winds / stall problems.Any advice on good settings would be greatly appreciated.All the best,Armen
