Hi,

Is this occuring in flight? Or during the set-up process.

Thanks!

All the time.

Okay, do you have any discontinuities in your flight plan?

No.

Can also confirm.
Just as one reaches TOC, the prediction suddenly changes to a value that comes close to the prediction in simbrief.

Also: the initial cruising alt from simbrief (offical inibuilds A380 profile) is always 2-4k ft lower than the actual optimum altitude in the fms. Just as one reaches the end of the flightplan, the optimum cruise alt in the fms corresponds to the step alt profile from simbrief

Thanks, will log for the team!

I also have this error. It doesn't happen on every flight, but even though the fuel load is correct in the plane, the A380 shows an error message. As soon as I take off and start climbing, it begins recalculating the fuel. Right after takeoff, it gets better, but it's still not completely correct. I know I have enough fuel obviously, but I just wanted to point this out

Thanks! Will add this with my report to the team.
