Understanding the Value of Custom Airport Scenery

Default airport scenery in AeroSimulations provides a functional but often generic representation of real-world airports. Custom airport packages transform these locations into highly detailed, accurate replicas that include correct runway markings, terminal buildings, parking positions, night lighting, and even nearby landmarks. For serious sim pilots, installing high-quality airport scenery is one of the most rewarding upgrades you can make to your virtual cockpit. However, a haphazard installation can lead to performance degradation, texture blackouts, and frustrating conflicts between add-ons. This guide walks you through every stage of the process—from system preparation to ongoing optimization—so you can enjoy crisp, smooth airports without technical headaches.

System Preparation: Laying a Stable Foundation

Before downloading any scenery, confirm that your computer meets the recommended specifications. While AeroSimulations has relatively modest baseline requirements, complex airport packages, especially those with high-resolution textures, 3D animated objects, and advanced lighting, demand more. A multi-core processor operating at 3.0 GHz or higher, at least 16 GB of RAM, and a dedicated GPU with 4 GB or more VRAM are ideal. If your system is borderline, consider upscaling memory or reducing expected texture resolution in advance.

Next, create a backup of your current scenery.cfg file and the entire Scenery directory. A simple copy-paste to a separate folder will allow you to revert changes if anything goes wrong during installation. Also, ensure your video drivers are up to date; outdated GPU drivers are a common source of scenery-related visual glitches. Finally, clean out your temporary files and defragment your drive (if using an HDD) to prevent read latency when loading large scenery areas.

Software Prerequisites and Tools

Many airport packages require additional libraries such as FSUIPC (for SimConnect connectivity), Orbx Libraries, or specific object libraries (e.g., REX ObjectFlow). Check the documentation for each scenery package and download any prerequisite libraries before you begin. Also consider installing a scenery management tool like Scenery Manager or Addon Manager by FS-FlightControl; these utilities simplify enabling/disabling layers and detecting conflicts.

Downloading Airport Scenery: Trusted Sources and Version Checks

Quality matters, both in visual fidelity and in code safety. Only download from reputable sources to avoid corrupted files, malware, or poorly optimized scenery.

  • FlightSim.com—The largest freeware library, with community reviews and screenshots.
  • AVSIM—Another comprehensive library with forums for troubleshooting.
  • Orbx Direct—Premium payware scenery known for consistency and stability.
  • AeroSimulations Official Website—Many developers release directly through the platform’s marketplace.

Always verify that the package version matches your AeroSimulations build. An installer designed for an older version may not place files correctly or may cause errors. If you are using a Steam edition, watch for packages that explicitly support that distribution channel.

Step-by-Step Installation Process

Although every package may include unique instructions, the general workflow remains consistent. Follow these steps carefully.

1. Extract the Archive

Most scenery comes as a .zip or .rar archive. Use a tool like 7-Zip or WinRAR to extract the contents into a working folder. Avoid extracting directly into the AeroSimulations Scenery directory; instead, extract to a temporary folder so you can review the structure and read any included documents.

2. Identify the Installation Method

There are two common approaches:

  • Legacy method: Manual folder copy into Scenery directory, followed by editing scenery.cfg or using the in-game scenery library.
  • Add-on.xml method: Many modern packages include an add-on.xml file. This allows AeroSimulations to automatically detect and manage the scenery without manual file placement. Simply copy the entire package folder into the AeroSimulations Add-ons folder (located in your Documents directory).

Check the package’s documentation. If an add-on.xml is present, use that method as it simplifies management. For legacy packages, proceed to the next step.

3. Copy Scenery Files

For legacy installations, locate your AeroSimulations installation directory (usually C:\Program Files (x86)\Aerosoft\Aerosimulator or similar). Inside, find the Scenery folder. Copy the extracted scenery subfolder(s) into this directory. For large packages, this may take several minutes. Ensure the folder name is descriptive (e.g., KJFK - New York JFK v2) to distinguish it later in the scenery library.

4. Add the Scenery to the Library

Launch AeroSimulations. Go to Settings > Scenery Library. Click Add Area or Browse (the exact label varies by version). Navigate to the folder you just copied and select it. Confirm the addition and set the priority. Lower numbers indicate higher priority; place custom airports above default scenery layers (usually at the top of the list). After adding, click OK and allow the program to rescan and rebuild the terrain database. This scan can take several minutes depending on the number of files.

5. Verify Installation

After the scan completes, navigate to the airport in the simulator. Check that buildings, runways, and taxiways appear correctly. If textures are missing (purple/black), you may be missing required libraries or have a corrupt file. Re-read the package documentation and ensure all dependencies are installed.

Optimizing Airport Scenery Performance

Even beautifully designed scenery can cripple your frame rate if not properly tuned. The goal is to strike a balance between visual fidelity and smooth operation.

Adjust Graphics Settings

  • Texture Resolution: Lower this to 1024x1024 or 2048x2048 if you experience stuttering. High-end systems can handle 4096x4096 but keep an eye on VRAM usage.
  • Shadow Quality: Reduce shadow resolution or turn off shadows for scenery objects. Realistic shadows are a major FPS hit.
  • LOD Radius: Increase the Level of Detail radius only if you have a powerful CPU. A smaller radius can drastically improve performance in dense airport areas.
  • Autogen Density: Keep this at Normal or Dense. Very Dense can overwhelm even top systems.
  • Anti-aliasing: Use the moderate MSAA 4x or FXAA. Avoid MSAA 8x.

Hardware and System Optimizations

Upgrading to an SSD is the single most impactful hardware change for loading scenery and reducing stutter during texture streaming. If you are already on an SSD, ensure the drive has at least 15% free space. Keep background applications minimized, especially those with high GPU usage like web browsers with hardware acceleration turned on. Use a tool like Process Lasso to assign AeroSimulations to dedicated CPU cores and prevent other processes from interrupting.

Scenery Layer Management

The order of your scenery layers matters. Always position custom airports above default scenery and large region packs (e.g., Orbx Global). Conflicting layers—where two scenery packages modify the same airport area—should be resolved by disabling one. Use the Scenery Manager to quickly toggle layers on and off during troubleshooting. Keep the number of active layers to a minimum. Each active layer increases loading time and can reduce performance.

Advanced Optimization Techniques

Shader and Post-Processing Tweaks

Tools like P3D v5/v6 Shader Suite or Reshade can enhance lighting and color, but they also add GPU overhead. If you use such tools, create a specific preset for airport-intensive scenarios that reduces bloom and reflection effects. Alternatively, disable them entirely when flying into complex airports.

Mesh Resolution

Some airport packages include custom elevation data (mesh). If you also have a global mesh product like FreeMeshX, ensure the airport mesh takes priority (higher in the scenery library). Conflicting meshes can cause jagged terrain or runways floating above the ground. Set mesh resolution in the simulator to 5m for the best detail, but lower to 10m or 20m if you experience ground texture tearing.

Texture Compression

If you have high-VRAM textures and limited capacity, consider compressing them using DXT5 or BC3 via a tool like VBricks or Imagetool. This reduces quality but can save significant VRAM. Only do this if you are comfortable editing scenery files and can revert if results are unsatisfactory.

Maintaining and Updating Your Scenery Library

A well-maintained scenery library runs smoother and avoids conflicts. Set a monthly routine.

  • Check for Updates: Visit the original download pages or use update utilities provided by payware developers. Many packages receive bug fixes and performance improvements.
  • Remove Unused Scenery: Uninstall airports you no longer fly to. Use the in-game library or a tool to remove layers cleanly (deleting the folder alone may leave entries in scenery.cfg).
  • Clean the Shader Cache: Periodically delete the shader cache folder (usually in %LOCALAPPDATA%\Aerosoft\Aerosimulator\Shaders). This forces the GPU to rebuild shaders and can eliminate corrupted cache issues that cause shimmering or artifacts.
  • Verify File Integrity: If you suspect file corruption, use the AeroSimulations Launcher’s Repair function or reinstall the specific package.

Troubleshooting Common Issues

Missing Textures (Purple or Black Surfaces)

This usually indicates missing textures or libraries. Check that all dependencies (listed in the package manual) are installed. Also ensure the texture files weren’t deleted during extraction. If using a compressed format, your antivirus might have quarantined them.

Low Frame Rate at a Specific Airport

First, verify if the issue is present with all other scenery disabled. If only certain airports cause stuttering, reduce their texture resolution or disable dynamic lighting in the package settings (if available). Also check for overlapping scenery—two packages covering the same area can double the object count.

Runway or Taxiway Elevation Mismatch

When the runway appears sunken or raised compared to the surrounding terrain, the scenery library layer priority is likely incorrect. Move the airport layer above any terrain mesh layers. If the issue persists, the package may require a specific mesh product as a base.

Steam Version vs. Standalone Version

Some scenery packages are built exclusively for the standalone (boxed) version and may not detect the Steam version correctly. Look for a separate installer, or manually modify the add-on.xml to point to the correct path. Community forums often provide patches for such compatibility issues.

Community Resources and Final Advice

Do not hesitate to visit the Aerosoft Forum or the AVSIM forums for specific package support. Many developers and experienced users share tweaks, conflict solutions, and performance profiles. Always read the comments and reviews on download pages before installing a new package; they often reveal common pitfalls.

Remember that optimization is an ongoing process. As you add more scenery, periodically revisit your graphics settings and scenery priority list. The most stable setup is one where you understand every layer and why it exists. By following the preparation, installation, and optimization steps outlined here, you can build a virtual world that looks stunning and runs reliably, letting you focus on what matters most: the flying itself.
