I’m using Xbox Series X + MSFS 2024 + iniBuilds A350.

The problem occurs when starting the aircraft from a Cold & Dark state. I follow the normal startup procedure and import my SimBrief flight plan through the EFB. Flt Ops Sts and Load Sheet information both load normally.

However, when I perform FPLN Request on the FMS, it remains stuck on “Pending Request” for about 20 seconds and then automatically returns to the previous screen. The flight plan is never loaded.

I have repeatedly tried various troubleshooting methods, including re-importing the SimBrief flight plan, restarting the aircraft, reloading the flight, sending the FPLN Request again, switching through CAPT OIS/Center OIS and then importing again, as well as other related settings and procedures. I believe I have already tried pretty much all of the obvious troubleshooting steps.

I have also seen other Xbox Series X players on YouTube using this function successfully, so I’m wondering whether this could be related to corrupted A350 data, cached data, saved aircraft data, or an Xbox-specific bug.

If anyone knows how to completely reset the A350 data or fix the FPLN Request getting stuck on Pending, I would really appreciate your help.

Hi Carl,

Sorry to hear you’re experiencing issues with the A350 on Xbox. My first suggestion would be to uninstall and reinstall the aircraft through the in-game marketplace, as this can sometimes resolve issues caused by corrupted or incomplete files.

Let me know if that helps.

Thanks!

I re-downloaded and reinstalled the A350 through the in-game Marketplace, then completely restarted MSFS 2024 and tested again.

Unfortunately, the issue remains exactly the same.

I’m using Xbox Series X. In Cold & Dark, SimBrief import works normally, and Flt Ops Sts and Load Sheet load correctly. However, FMS FPLN Request stays on “Pending Request” for about 10–20 seconds and then returns without loading the flight plan.

I have also tested both SIMDEFAULT and NAVIGRAPH NAVDATA sources, with the same result.

Could you please investigate whether this is a known Xbox-specific issue?

Hi Carl,

Thanks for your help with the troubleshooting. I’ll forward this over to a team member with an Xbox and have them test it. I’ll report back once they’ve had a chance to investigate.

Thank you again for your time and help!
