@Kostas: As far as I understood you correctly, ASN is using forecasted wind data within ASN's internal flight planner. This is a very important point for me, as I'm not using this planner. My question is now whether ASN also exports this forecasted data to PFPX, because this is doing my wind and fuel predictions. If I use PFPX' own wind data, I'm having a small slider to change the time for those wind arrows, with ASN data in PFPX this slider is greyed out:
PFPX
ASN
