I'll do another flight and record all the datas. For example over England and over the ocean I had my winds liked at 332/123kt. After disabling true wind aloft the speed dropped but the direction was still wrong as I was expecting headwind(265°).
I was using chart from https://aviationweather.gov/iffdp/fdwndc
