Out of interest Christian what are your payload and pax figures? I've had it before on a reload that the number of pax is higher than what is actually allowed, so say in the two class cabin I have 12 allowed it shown 15, obviously this would effect gw if something getting corrupt.Try emptying your plane of fuel, pax, cargo, then load as normal then try flight and see if same issue occurs?

Hi James,in my example above I did a ~2 hours flight (EDDF-LEPA) with Full PAX/Cargo and Yes it was 15 in the first class !The difference nearly 12000 lbs at the FAF seems too much.Later I´ll try another flight with the 12 allowed. Thanks !
