A321neo EFB/SimBrief Fuel Not Applying to Aircraft (ECAM Tanks Stay Empty)

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.
