"AES" stands for "Airport Enhancement Services" and is an add-on for "Microsoft Flight Simulator X" or "FSX," as it is commonly known. The "AES" pack is available from a company called Aerosoft and is comprised of new modules that run from within FSX. These modules change the way that you interact with the airports in the simulator and makes for a more realistic experience. The "AES" base pack is a free download, but accessing some of the airports contained in it requires "credits" which you can purchase online.

Navigate to the Aerosoft website ( and download the latest version of the "AES base pack."

Right click on the archived file after the download is complete and then select "Extract All" from the pop-up menu. This will leave you with an executable file and the license agreement file.

Double click the license agreement and read through it. Close the license agreement and then double click the "AS_Airport-Enhancement-Services_V212.exe" file to start the installation.

Select the language for the installation from the drop down menu and then click "Ok." Click "Next" and then click "I accept the terms of the license agreement."

Click the radio button next to "Microsoft Flight Simulator X" when the installer asks you which features you want to install. Click "Next" and the installer will automatically detect the folder where your copy of "FSX" is installed. Click "Finish" once the installation is complete.

Double click the "AESHelp" shortcut icon on your desktop to add credits and activate airports if you so wish. This is entirely optional and there are free airports included in the package, so you can try them out before deciding if you want to spend cash on the others.

Exit "AESHelp" and then start your copy of "FSX." Click "Yes" twice when asked if you want to designate the "module as authentic." What this does is acknowledge that the AES software is allowed to start every time you run "FSX."

Press "Control"+"Shift"+"W" to bring up the "AES" main menu from within FSX.
