A340 – AOC INIT / INIT REQUEST Fails, FMGC Uplink Not Working (No Data Download)

Hello, I am experiencing a major issue with the A340 FMGC / AOC systems.

For the past week, the aircraft has been unable to download any operational data through the MCDU. The following functions fail every time:

• INIT REQUEST → returns “ERROR DOWNLOADING DATA”

• AOC FLT INIT → does not populate fields automatically

• AOC RTE UPLINK → no route uplink

• VERIFY → SEND → does nothing, no uplink

• FMGC does not receive any company route or weather data

I have attached screenshots showing:

• INIT page stuck with “ERROR DOWNLOADING DATA”

• AOC FLT INIT not receiving dispatch data

• ATC MENU and AOC MENU pages functioning, but uplink actions fail

• VERIFY/SEND page not transmitting anything

I have already:

• Reinstalled the A340

• Cleared rolling cache

• Restarted MSFS 2024

• Tried multiple airports (CYOW, KPHL, KIAD)

• Tried multiple flight numbers

• Tested with and without SimBrief integration

The issue persists across all flights.

This looks like a deeper FMGC/AOC logic failure. Please advise — I have also submitted a Direct Support ticket 8 days ago but have not received a reply.

Thank you.
