Hi Ini team,

I would like to report a bug affecting the iniBuilds A321neo on Xbox Series X after Sim Update 5, including the current SU5 beta/hotfix.

When importing payload/fuel through the iniBuilds EFB using SimBrief data, the values appear correctly inside the MCDU: BLOCK fuel, FOB predictions, ZFW/ZFWCG, etc.

However, the aircraft itself does not actually receive the fuel.

On the ECAM FUEL page:

• all tanks remain at 0

• FOB stays at 0 KG

• fuel flow remains at 0

• fuel warnings appear as if the aircraft is empty

At the same time, the MCDU clearly shows the imported fuel values and calculations correctly.

Important details:

• this happens only with the iniBuilds A321neo

• the iniBuilds A320neo works correctly

• the iniBuilds A330 works correctly

• if fuel is set manually through the default MSFS tablet/interface, it applies correctly to the aircraft

• the issue seems specifically related to the EFB → SimBrief → aircraft fuel synchronization process after SU5

Platform:

• Xbox Series X

Version:

• Sim Update 5

• current SU5 beta/hotfix

I attached screenshots showing:

1. EFB payload/fuel correctly loaded

2. MCDU fuel predictions correctly calculated

3. ECAM fuel page still showing 0 fuel everywhere

Thank you very much for your work and support.

Thanks! Also other simmers are facing the same issue: https://forums.flightsimulator.com/t/a321lr-fuel-load-in-efb-does-not-equal-fob/749981/8 ! Some had this problem even before SU5. I personally started encountering it after SU5, even on beta. A20N & A330 are fine.

The other thing to add is that if you set the fuel up using the A321 configuration screen (the only way to control it at present), it fills the aux tanks and centre tanks first. This makes no sense. I was able to switch centre fuel tank to MANUAL which pumped the fuel into the wings but the aux tanks remained unusable.

Edit: As my wing tanks got very low, ECAM low fuel cautions on, fuel started to come out of the FWD aux tank. Surely that aux fuel would be used first in cruise.
