How to - Download Terrain Data via the EFB

[richboy2307]

 

The Navigation Display (ND) on the iniBuilds A340 Airliner can display terrain and obstacles information when the TERR ON ND pushbutton is pressed. This function relies on a Terrain Database which is downloadable via the Electronic Flight Bag (EFB) - 3RD PARTY SETTINGS page.

Why is this required?

• This process helps ensure terrain data integrity by minimizing risk of corruption whilst streaming the package.
• This process reduces overall bandwidth usage whilst streaming the package.

When is this required?

• This process only needs to be done once when you first launch he A340 Airliner after your purchase.
• The process does not need to be repeated for each variant, as the database is shared between EIS1 and EIS2.
• The process does not need to be repeated when updating the aircraft - unless stated specifically in the changelog.
• The process is only required again IF you manually delete your Terrain database (.bin) file which is located within the WASM/Work folder.

Note: Clearing your WASM/work folder will also delete the Terrain database file. You will need to repeat the process in that instance.

How to download terrain data?

1. Navigate to the Settings > 3rd Party Settings > Download Terrain Data section on the EFB
2. Press the DOWNLOAD button and wait for the download to complete.
3. Once completed, you will see a notification at the top of the EFB Display.
4. Press ESC to return to main menu and restart your flight for the changes to take effect properly.

Note: The Terrain database (.bin) file is 285 MB in full which is downloaded in two parts. These are automatically combined into a single file at the end. Please be patient and allow some time for the process to complete. 

On a 100mpbs connection, the process is usually completed within 60s.

Note: The sim may freeze during the process as data is transferred within the sim Virtual File System (VFS). Please be patient and allow some time for the process to complete.

Troubleshooting

You may delete your Terrain Database file (iniTerrainV2.bin) manually and then re-download it via the EFB in case you experience any issues.

The file is located in the WASM/Work folder at the path below depending on where you purchased your simulator:

Steam: %APPDATA%\Microsoft Flight Simulator 2024\WASM\MSFS2024\inibuilds-aircraft-a340\work\
MS Store: %LOCALAPPDATA%\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalState\WASM\MSFS2024\inibuilds-aircraft-a340\work\

AV False-Flags

Certain antivirus software like MS Defender may falsely flag the Terrain Database file (iniTerrainV2.bin) for quarantine. In case you have any issues, please add an exclusion for the following folders:
