Fuel and Load always getting N - N or NEGATIVE VALUES on long haul flights

[garett_09]

Hello,

 

after entering the information from simbrief and using the correct aircraft in simbrief, when im flying a long haul flight like 14-15 hours, i am always getting this error in the FMS. I cant find anyway to fix it even by re-entering the values again, adjusting the CL, adjusting the fuel by small increments, changing the tropopause. 
 

this happens when the aircraft is fully loaded and is full of fuel. It doesnt happen on light flights like 5-8 hours. 
 

Using XBOX series X running 1.1.9 and still hasnt been fixed. 
 

plane: airbus a350-900 ULR as well as other a350 variants.

This is really getting frustrating. Im running v1.1.9

 

i can never do long haul flights with this plane.

Happened to me on the A350 and A330 also. 

mainly happens with me after adding the step climbs but when i dont add them everything works fine

Well, i guess there is one way to replicate it. I have auto import step climbs and i think that is also the reason. I will try to turn it off then add the fuel and load ad add the step climbs after then i will report back here.

used to happen even on the 330 so i dont think the auto import is the issue

The issue is on the plane itself im guessing. When im manually applying the step climbs and not placing in the FMS, it doesn’t give me a negative value or a crazy value. 
 

only happens when applying in the FMS
