JeeHell FMGS

I will have a look when I can on that. Thanks for the heads up and fix.

1) correct though there saw some 3rd party addon that enabled some compatibility, not from so I won't be able to elaborate
2) when ready it will maybe use default aircraft 3d model, but everything else will be independent

There is some work on it obviously but this take stile and I am very limited on time at the moment.

Fuel used and fuel computation for actual tank consumption are in different places, and use different time delta it seems. If the FF varies a lot, then one is more averaged than the other. I need to do more tests. My tests were very simple, no turbulence etc so N1 did not change at all and i didn’t ...

And also, how much CPU is used on your PC? is it "tight"?

do you use a simulation rate different than 1x to speed up your flights?
For my tests I did a long flight, I burned 12500 kg and FOB + FUSED was accurate to the nearest 10kg...
Do you turn APU OFF?

I made inflight tests, and there were no issues here.
Do you have P3D and FMGS server on different PCs?
Does your P3D start situation have engines running or not?
Do you have another addon opened at the same time that could be changing fuel?

And does anybody else have the problem??

Check the CPU usage with task manager.
When you say freeze, you mean they stop once and for all, or they are actually stuttering?
Make sure your antivirus is not blocking as well.

sure, give me a name/email to contact at mobiflight.

I did a first test on the ground only for now, and there is no issue. Did you have the problem on the ground as well?
