StefanBravo 0 Posted June 6, 2020 Share Posted June 6, 2020 Hi all, I noticed on all my flights that there is a difference of about 500 kgs between the ZFW indicated by the EFB and the one indicated by the FMS. The one in the FMS corresponds with my PFPX calculations. Please login to display this image. Please login to display this image. Is this a bug or am I missing something?

Developer Hans Hartmann 3694 Posted June 7, 2020 Developer Share Posted June 7, 2020 Those two systems are actually not connected except in the very moment when you press "COPY PERF INIT DATA TO FMS". I don't know how PFPX calculates things, but apparently they don't do it like we do. There's probably a difference in the BOW they use. Link to comment Share on other sites More sharing options...
StefanBravo 0 Posted June 7, 2020 Author Share Posted June 7, 2020 Hi Hans, Thanks for your answer. As a matter of fact, I did copy the performance data to the FMS. In both screenshots, there are 50 passengers, 900 kgs of cargo and 2200 kgs of fuel. However, in the EFB this yields a ZFW of 25848 kgs, and the FMS comes up with 25386 kgs. It's only a difference of about 500 kgs, but shouldn't these two values be identical? Stefan Link to comment Share on other sites More sharing options...

Max ZFW depends on several factors and is not always the same for every aircraft/airline. ( including same models/type. ) Link to comment Share on other sites More sharing options...
