Hello guys!

I have been experiencing an issue with the Airbus A350's (latest 1.2.6 build) terrain display on the ND, and I'd like to ask for help.
The terrain display intermittently fails to initialize for an entire flight.

When the issue occurs, TERR can be selected normally on the ND, but no terrain is displayed and the TERR indications remain:

HIGH 0
LOW 0

The problem is intermittent. For example, the terrain system may work normally on one flight, fail completely on the next flight, and work normally again on a subsequent flight without any changes to the terrain database or aircraft configuration.

When the issue occurred, I verified the following:

• OIS → 3rd Party showed Terrain downloaded.

• Navigraph was authenticated.

• ANF was working normally.

• The iniTerrainV2.bin terrain database was present.

• Liveries are installed normally through iniManager and are not being dynamically linked through MSFS Addons Linker.

I have also found reports from other users, describing basically the same behavior.

I would be happy to provide screenshots, logs, flight details, or perform additional troubleshooting if there is specific diagnostic information that would help identify the cause.

Hi,

I’ll have to take a look at this on my end, as I don’t recall ever experiencing this issue myself. If you’re able to grab a video the next time it happens, that would be greatly appreciated and should help us investigate further.

Thanks!

Hi,

Absolutely. Should it happen anytime again, I'll make a recording for you.

Thank you!

Hi again!

One more thing! I've made a mistake by creating this topic here in the MSFS 2020 forum. In fact however, I am using MSFS 2024, not MSFS 2020. What can I do? Do you need me to repost this over there as well?

Sorry again for the inconvenience and thank you!

Thanks for the clarification! I have moved it over to 2024 for you 😊

Hello, it's me again!

I've managed to reproduce the terrain radar issue. Unfortunatelly I could not upload a video due to the file size limit here, but I've taken a few screenshots of all of the displays. I apologize if the images are a bit bright, I had HDR enabled. I hope it won't be a problem!

The steps I did to reproduce the bug:

• Launched MSFS 2024

• Went to Free Flight and selected the A350

• I switched liveries from Delta to Lufthansa

• Started the flight in Cold & Dark then powered up the aircraft

• When the IRS alignment process was completed and I tried the terrain radar, there was the issue

After I restarted the sim and went back to the same airport (JFK), did everything the same way, the terrain radar worked fine. After that I did a few more attempts, tried changing up things, switching liveries before flying or using the same, waiting before powering up the aircraft, changing up the pace of starting things etc, it's been stable ever since.

The only difference I've noticed between the attempts is that I got the A/C POSITION INVALID warning message on the MESSAGES LIST page in the FMGS. That message seemed to be a clue, but it came up in two startups, yet the terrain radar has been working regardless ever since the very first attempt.

Let me know if there is anything else I can do and if there is any update on your end.

Thanks.
