Hi anybody using vrout for calculation of fuel pmdg 747 400 ? I normaly use fsbuild very realiable ,but I also use vrout for pmdg js 41 ,pmdg 738 and calculations are very close ,but 747 400 is very low ,actually is way too low. Example would be OMDB - YSSY I get nearly 60 000 pounds les then fsbuild,topcat and my own calculation which would be very simple just flight time . With vrout I woudnt even made it over water .
has anybody any tip why that could be ? thanks Petr
