When I import a flightplan from Simbrief, with the "Load PERF DATA with Flightplan" option in the EFB enabled, the correct ZFW is displayed in the FMS..
After that i go to the EFB and insert the same Data from my Flightplan to get my Vspeeds and "load" the Plane with the correct weight. But there´s the Problem. When I enter the ZFW and the Fuel into the EFB and press "SET PAYLOAD IN SIMULATOR" and "COPY PERF INIT DATA TO FMS" (twice), the FMS now gives me the wrong ZFW.
((Below this message you can see the FMS after i pressed the SET PAY
