Why is my Download is Slow?

Our Downloads are hosted on a CDN at a data centre, you should be getting your normal download speeds.

However a few people have connected to a bad server and receive a slow download (around 100kbps)

To resolve this,
-Open Command Prompt from your start menu on your PC.
-Type: ipconfig /flushdns
-Press Enter

Then try to download again.
Also sometimes a Restart of the PC may be required.

Where does my Download go?

You must install your purchase to the Microsoft Flight Simulator Community Folder.

Unzip your ZIP File and place the root folder into the community folder.

Where is my Community Folder?

The Community folder of your Microsoft Flight Simulator 2020 installation is the place where scenery add-ons and liveries are installed by dropping the downloaded folders in there.

Microsoft Store version:

Steam version:

C:\Users\%USERNAME%\AppData\Roaming\Microsoft Flight Simulator\Packages\Community\

If AppData folder is not showing up in your Windows Explorer, type %AppData% or %LocalAppData% in Windows search bar and press enter to open your AppData folder.

I can't unzip my folder or "Path Too Long" Error

We try to keep our naming short, however some of our older scenerys have some longer file names

You can get around this by:

Unzipping your Folder to a higher level directory then moving it into your Community Folder
eg. Make a folder called “temp,” directly on your HDD. “C:\temp”
Then unzip it to there and copy it to the community folder.

You can also try using WinRAR or 7-Zip to unzip your folder.

What is the NZA Model Library and what do I do with it?

The unzipped Model Library goes into the Community folder as a separate package, the same way as the normal scenery packages do.

This library contains our common assets and is used by our freeware and payware airports. The model library supplies key assets which will not render correctly if the latest version of the library is not installed.
This way we can optimise space on your computer and it also makes it easier to keep our models working correctly without conflicts or having to update everything.

Important: This Model library is not to be used for anything other than NZA Simulations products. For further information see our Terms and Conditions.

I can't see my new scenery in the sim or its not showing up as a star airport on the world map.

Some people have had issues with folder names, possibly from attempts of installing part packages.

You can change the root folder name inside the community folder to just the Airport name eg. “Airport” or “ICAO” and it should load in ok.

eg: nzasimulations-ymhb to nza-hobart

By doing this it will force update the Contents.xml for your community folder.

You can also try delete the Contents.xml file which is located in your main install path of the MSFS2020.
Then once you start the sim it will rebuild a new fresh one.
We recommend backing it up first so that if the sim doesn’t start anymore you can put it back in. As this was an issue prior to Sim Update 6.

Why can't I see some scenery assets such as; street signs, hedges & static aircraft?

You will need to install our NZA Model Library separately into your community folder.

This library contains our common assets, and is used by several of our freeware and payware airports. The model library supplies key assets which will not render if the latest version of the library is not installed.

Performance Guide


NZA’s Proline™ airports use the latest in 2D and 3D technologies to ensure an airport that will look beautiful now and into the future. Because of this some low end systems will notice a small performance hit when using our scenery.
We do try to optimise our product as much as possible, however the SDK is limited in what we can adjust for different users.
Because of this we optimise it for High End Preset for majority of users with Mid to high end PCs as per the MSFS SDK documentation. 

Low End Systems
Please try the following options on lower end systems – 4GB or less of VRAM or CPU earlier than i5-4760:
• Medium Graphics present
• Resolution equal to or less then 1920×1080
• Texture Resolution medium or low (will lower 4k textures to 2k textures etc)
• Object Level of Detail Slider ≤50 (Adjusts the range objects will load in high resolution textures and high detail models)

Stuttering is usually caused by the computer running many tasks or because there is a throughput issue with memory moving from your disk through memory into VRAM
Large stutters most likely indicate a disk IO and or RAM bottleneck.
• Ensure you have the simulator and your Proline™ scenery installed on an SSD
• We recommend having at least 16GB of ram if you have less installed please turn down texture resolution setting to medium or low

Streaming content from the sim uses a significant amount of CPU overhead as well as loading your disk.
If streaming/recording you will want to point your capture to a separate disk to the one the simulator is running off.

In general see the Low End System section and adjust the Texture Resolution or Level of Detail Slider accordingly to improve performance.

Our latest scenery are well optimised with multiple LOD’s and optimised texturing to allow for the most detailed scenery.
