How to Install Add-on Aircraft in FSX: Steam Edition

Adding aircraft to Microsoft Flight Simulator has been a popular way of enhancing the simulation experience for many years. With the introduction of FSX: Steam Edition, a new generation of flight simmers has this wonderful opportunity.

This tutorial explains three basic methods for enhancing your FSX: Steam Edition with third-party add-on aircraft:

We have also created a video that shows the same procedures in video format for ease of use. It saves you reading pages of text and you can pause/play the video when needed: Jump straight to the video here.

Before you try installing add-ons you need packages that you can download - you can download over 22,000 add-ons for FSX:SE over in the library here.

Finding FSX Steam's Aircraft on Your Computer

For each installation method, you need to know where to put your new aircraft files. FSX Steam’s aircraft files are kept in a dedicated folder within the FSX Steam program files. FSX Steam usually installs to the same place on most computers because of how Windows works. That is the Program Files (x86) folder. FSX: Steam Edition will be there unless you chose a different location when you installed it.

  1. Open your Windows Explorer file manager.
  2. Double click on the following folders, one after another, in this order:
    1. C:
    2. Program Files (x86)
    3. Steam
    4. steamapps
    5. common
    6. FSX
    7. SimObjects
    8. Airplanes (or Rotorcraft)

The path shown in the top line of your Windows Explorer is your destination to FSX Steam. It results from the folders you double clicked. Use the Airplanes folder to add airplanes and the Rotorcraft folder to add helicopters.

File Manager 1

C:/Program Files (x86)/Steam/steamapps/common/FSX/SimObjects/Airplanes (or Rotorcraft)


Installing Freeware Aircraft With Base Model Included

Adding freeware aircraft from a downloaded file with base model included is a multistep process.

Choose and download an addon aircraft from Fly Away Simulation.

Fly Away Simulation Aircraft Download

Open your newly downloaded file. If you don’t see it on your Windows desktop, use Windows Explorer to look for your file in your Downloads folder.

You will see all the folders and files the developer included for using his add-on aircraft. Most developers provide a text file with instructions. Open that text file and do what it tells you to do. If no instruction file is included, extract the entire aircraft set with all its folders and files to the FSX Steam file path that was identified previously.

File Extraction 1

Look inside the FSX Steam Airplanes or Rotorcraft folder for the aircraft you added. If your new aircraft is not in that folder, redo the extraction procedure, making sure you used the correct FSX Steam destination path.

File Extraction 1

Then look inside your new aircraft’s folder for its folders and files. They should be the same folders and files that are inside the archive file you downloaded from Fly Away Simulation. If they are not all there, redo the extraction procedure, making sure you extract all the needed files.

File Extraction 1

Open your FSX Steam. Look through the list of available aircraft. Your newly added aircraft should be among those aircraft. Click on your new aircraft to select it, then click on the OK button in the lower right.

Aircraft Selection Menu 1

If you saw your add-on aircraft in the Airplanes or Rotorcraft folders but you don’t see your aircraft among the FSX Steam collection, look under the manufacturer, publisher and aircraft-type categories. Some third-party developers don’t categorize their aircraft accurately.

If you are sure your new aircraft is in the Airplanes folder, and you have looked throughout the aircraft collection and still don’t see your new aircraft, then go to your new aircraft’s Panel folder.

Aircraft Selection Menu 1

Open the panel configuration file. It’s a standard text file that opens with ordinary text programs such as Windows Notepad.

Aircraft Selection Menu 1

The panel configuration file should show lines of code for FSX Steam to follow.

Aircraft Selection Menu 1

Or it should direct FSX Steam to use a different panel from a different aircraft.

Aircraft Selection Menu 1

If the panel configuration file references a panel that Steam cannot find, the aircraft will not be displayed. Revise the code to reference an aircraft you have, or ask the developer of your add-on aircraft for the needed panel code.


Installing Repaints for Already Installed Aircraft

Installing repaints for FSX Steam stock aircraft and for third-party aircraft already added to your FSX Steam require the same file-extraction procedures described previously, plus revisions of aircraft configuration files.

Select and download a repaint package from Fly Away Simulation.

Fly Away Repainted Aircraft Page

Extract all the new texture folders to the specific FSX Steam aircraft for your repaints. This example is a repaint for the stock Boeing 747. Some developers add one texture, and some add several textures. This developer made four texture sets.

File Extraction 2

Go to the respective aircraft folder in your FSX Steam (Airplanes or Rotorcraft) and verify that the new texture folders have been added.

Textures Folders

The file-revision procedure should be explained in a text file provided by the aircraft developer. Follow his instructions precisely. If a text file with that information is not included, contact the developer for his instructions. The textures cannot appear without the file revisions.

File Revisions

Copy configuration data from the developer’s file. If the developer made more than one texture, there will be more data to copy than seen in this window.

Developer's Configuration Data

Open the configuration file for the FSX Steam aircraft to be repainted. It’s always named “aircraft.cfg” for each aircraft, and it’s a standard text file.

Aircraft Configuration File

Notice that each texture group for this aircraft is numbered sequentially starting with zero.

Aircraft Configuration File

Scroll down to the end of the aircraft texture section. Paste the developer’s repaint data into the aircraft.cfg file.

Paste Texture Codes

Then renumber his new data groups to make them next in the sequence.

Renumber Textures

Make sure the texture names in the aircraft.cfg file match the names of the texture folders. If they don't match, the repaint cannot be displayed.

Texture Names

If your repaints don’t appear properly in FSX Steam, check the sequence numbers and the texture names. Also check the developer’s instructions to be sure you followed them correctly. If you are sure everything is correct but your repaints still don’t appear, contact the repaint developer for assistance.


Using Direct X 10 Preview

Direct X is an internal program that facilitates graphics displays in Microsoft computer games, including Flight Simulator. DX10 wasn’t ready when FSX was released in 2006, so Microsoft included a preview option. DX10 Preview enhances the graphics display in FSX, but it also increases demands on the simulator and the computer that operates it.

If your add-on aircraft is black or invisible, uncheck your DX10 setting.

DX-10 Checkbox

A third-party program called Steve’s DX10 Scenery Fixer might be helpful. It has been independently tested and reviewed by Fly Away Simulation. For more information, go to his web page:, or search for “Steve’s DX10 Fixer.”

Getting Assistance

The first place to seek assistance is yourself. Reread all the instructions, double check all your work, look for possible mistakes, and correct them. We can usually find and fix our own errors in a tiny fraction of the time required for contacting developers and posting questions on internet forums. If you are absolutely sure you followed all the instructions correctly and made no mistakes, then contact the developer. He’s in the best position to help you. The last resort is internet forums if you don’t get assistance from the developer.

Video Demonstration

Below is a video outlining and demonstrating all of the methods uses above. Some users find it easier to follow a tutorial video.

Roger LavoieSun, 20 Aug 2017 19:03:49 GMT

Have just downloaded "" There are NO instructions for installing, none whatsoever!!! I have the old Nimitz installed on FSX steam. I guess this is supposed to be a "correction" to the original. Where does it go? Inside the already installed Nimitz folder? In the boats folder?

Aubrey FulfordSat, 17 Mar 2018 00:05:02 GMT

Can I run this on windows 10 64 bit ??

george schofieldMon, 02 Apr 2018 15:56:50 GMT

I do not seem to have a simobjects folder. Is there another place this might be? I am running windows 10 with fsx steam. Thank you.

PAUL GIULIANIMon, 26 Nov 2018 16:29:34 GMT

1. I have just downloaded 45 GB files of scenery and don't want to mess up the installation. There is no instruction included in the three .txt files.

2. Posted: Thu Dec 27, 2018 10:54 pm I also found this comment in text file:

"We officially recommend the use of FTX Vectors because all of our testing incorporates it, and it uses elevations derived from the SRTM dataset, the same dataset we use for FreeMeshX Global. To conclude, it does not make any sense to use a global mesh without using any updated vectors. Likewise it does not make sense to use updated vectors without using an updated mesh."

What are these "FTX Vectors" and how to find and install them???

I Appreciate this website especially the freeware download options. Many Thanks to all of the developers & FSX community around the world. Godspeed for all...

Richard ArcherWed, 07 Oct 2020 04:47:42 GMT

Dear Sir:

I am having some trouble downloading some airplanes from your website. Every time I download the airplane. The download says couldn't download. Is there any way to help me download the airplanes?

How To Install Planes In Prepar3D V3?

efuhrerThu, 14 Oct 2021 17:47:21 GMT

I am a novice at downloading add-on aircraft to FSX on Steam. I am interested in the Grumman aa-5 variants because I took my basic flight training on a Traveller. Many times I have downloaded the AA-5A&B zip files and attempted to expand the files and put them in the correct file locations.

The best result has been a flyable plane, but with mostly inoperable gauges. On closer inspection, I found comments that indicate the same problem.

Before I completely give up and unsubscribe I would like to know if this download is fully operable and I should keep trying or not.


truckertwotimes1Fri, 11 Mar 2022 08:52:07 GMT

Do these downloads work on MSFS goty on steam?
