Detailed Troubleshooting by Issue

Aircraft Not Appearing in the Aircraft Selection Menu

One of the most frustrating issues is loading P3D and finding the Aerosoft A320 missing from the list. This usually stems from an incomplete installation, missing SimObjects entries, or a corrupted add-on configuration file.

  • Re-run the Aerosoft Launcher – launch it and navigate to the A320 entry. Click “Repair” or “Reinstall” to restore missing files.
  • Verify the SimObjects folder – the A320 should be located in Prepar3D vX\SimObjects\Airplanes\Aerosoft Airbus A320 Professional. If the folder is empty or missing, the installation did not complete.
  • Clear the P3D shader cache – navigate to %LOCALAPPDATA%\Lockheed Martin\Prepar3D vX\Shaders and delete all files. Restart P3D – missing shader entries can sometimes hide add-on aircraft.
  • Check the add-ons.cfg file – open %PROGRAMDATA%\Lockheed Martin\Prepar3D vX\add-ons.cfg and ensure an entry exists for the Aerosoft A320. If missing, reinstalling or running the Aerosoft Launcher should regenerate it.

Performance Drops and Low Frame Rates

The Aerosoft A320 is relatively performance-friendly, but intensive P3D settings or add-on conflicts can tank frames. This section addresses the most common causes and fixes.

Optimise P3D Graphics Settings

  • Reduce or disable shadow quality and reflection detail in P3D settings.
  • Set tessellation to “Low” or “Off” if you experience stutters on approach.
  • Lower autogen draw distance and scenery complexity while troubleshooting.
  • Enable Fiber Frame Time Smoothing in Prepar3D’s settings under “Application”.

Manage Add-On Overload

  • Disable third-party weather engines (e.g., Active Sky, FSXWX) temporarily.
  • Turn off heavy airport sceneries with high object counts.
  • Restrict AI traffic to 20% or less during test flights.

Adjust Aerosoft A320 Configuration

  • Open the aircraft’s aircraft.cfg and look for the [LIGHTS] and [VIRTUALCOCKPIT] sections. Reduce the size of 2D panel bitmaps if applicable.
  • In the Aerosoft Launcher, set LOD Radius to a lower value (e.g., 3.5 instead of 5.0).
  • Disable unnecessary liveries to reduce memory load if you have many installed.
  • Update your graphics card drivers – especially NVIDIA or AMD Game Ready/Studio drivers. NVIDIA Driver Download

Cockpit Displays Not Functioning / Dark PFD

If the primary flight display (PFD), navigation display (ND), or engine/warning display remain blank or frozen, the issue is often linked to missing gauge DLLs, corrupted panel configurations, or incorrect aircraft state.

  • Verify the A320’s instruments are installed – check that the Gauges folder inside the A320 directory contains all required gauge files (A320_Core.DLL, A320_Display.dll, etc.). Reinstall if missing.
  • Check dependencies: The Aerosoft A320 relies on FSUIPC or the SimConnect interface from P3D. Ensure FSUIPC is installed (even the free version works). Re-register SimConnect via the SDK tools if needed. FSUIPC Download Page
  • Reset the aircraft default state – in the Aerosoft Launcher, click “Settings” and then “Reset to Default”. This resets the panel state and can revive unresponsive displays.
  • Delete the panel cache – go to %APPDATA%\Aerosoft\A320 Professional and remove the PanelState.ini file. Restart P3D.
  • Run P3D with /noexeclocks flag – add -noexeclocks to the target line of the Prepar3D shortcut. This sometimes resolves gauge initialisation timing issues.

Systems Not Powering On / Incorrect Electrical Logic

If batteries, APU, or engines refuse to start, or the electrical system behaves oddly, follow these steps:

  • Ensure you have followed the correct startup procedure – the Aerosoft A320 models realistic electrical logic. Start with the BAT switch, then APU bleed, then engine start. Refer to the included manual.
  • Check the aircraft state setting – in the Aerosoft Launcher under “Configuration”, choose “Ready for pushback” or “Cold & Dark” to see if the issue persists across different initial states.
  • Disable external power or GPU – some P3D airports cause conflicts with ground power. Manually disable GPU from the A320’s overhead panel.
  • Reinstall SimConnect – run SimConnect.msi from Prepar3D vX\redist\Interface\FSX-SP2-XPACK\retail\lib\SimConnect.msi to repair communication channels.

Installation Errors and Missing Files

During initial install or updates, users may encounter corrupt download archives or permission errors. These steps resolve the most common installation problems:

  • Download the latest full installer – avoid using very old versions. Always obtain the latest package from your Aerosoft account or simMarket.
  • Run the installer as Administrator – right-click the setup file and select “Run as Administrator”. Do not install to the default Program Files (x86) if you have strict UAC – instead point to a dedicated P3D folder on a different drive.
  • Disable antivirus temporarily – real-time scanning can block DLL registration. Turn it off during installation and reactivate afterwards.
  • Check disk space – the Aerosoft A320 requires at least 4 GB of free space. Also ensure the drive is not compressed.
  • Manual file check – if the installer reports missing cabinet files, download the archive again from a different server (e.g., use the Aerosoft server rather than a mirror). Aerosoft Downloads Page

Advanced Troubleshooting Techniques

Using Event Viewer or Crash Logs

When P3D crashes to desktop (CTD) while loading the A320, check Windows Event Viewer for error details. Look under “Windows Logs > Application” for “Faulting module name” – common ones are Sim1.dll, g2d.dll, or the A320’s own DLL. Searching these names can pinpoint a missing dependency.

Clean Testing Environment

Create a fresh P3D installation in a secondary folder (or use “Add-ons” method) with only the Aerosoft A320 installed. This isolates whether the issue comes from the aircraft itself or from another add-on.

  • Remove all other add-ons including scenery, other aircraft, and tools like Active Sky.
  • Test the A320 at a default airport (e.g., “KSEA” with default scenery).
  • If the problem disappears, reintroduce add-ons one by one until the conflict is found.

Re-registering DLLs and Gauges

Sometimes Windows loses registration of important modules. Open a Command Prompt as Administrator and run:

regsvr32 "C:\Program Files (x86)\Lockheed Martin\Prepar3D vX\SimObjects\Airplanes\Aerosoft Airbus A320 Professional\Gauges\A320_Core.dll"

Repeat for each gauge DLL. This manually re-registers the COM components.

Adjusting Prepar3D Configuration Files

Modify Prepar3D.cfg (located in %APPDATA%\Lockheed Martin\Prepar3D vX) to add:

  • FIBER_FRAME_TIME_FRACTION=0.15 – smoother frame pacing.
  • DisablePreload=1 – under [MAIN] to reduce load times.
  • QUAD_BOOST=1 – try if you have a high-core-count CPU (may help with A320 systems).

Always back up the original file before editing.

Additional Tips for a Smooth A320 Experience

  • Use the Aerosoft Forum and FAQs – many user-contributed solutions exist for specific liveries, regional updates, or FSUIPC integration. Aerosoft A320 Forum
  • Install the Aerosoft Update Manager – this tool notifies you of patches and hotfixes before they become visible on the forum.
  • Keep aircraft-specific liveries up to date – some third-party liveries can cause gauge errors. Use the official Aerosoft Livery Manager to remove them.
  • Consider switching to P3D v5/v6 if still on v4 – newer versions have improved memory handling and DirectX 12 support, which can stabilise complex add-ons.
  • Back up your A320 configuration – copy the entire “Aerosoft Airbus A320 Professional” folder after a successful install to save time if you ever need to restore.
