After downloading your X-Plane 10, you have to install the app. More you can read here.Click the Start menu, then My Computer. Double click on the XPLANE10 folder, then “Installer_Windows.exe”. When the installer window appears, click Continue to begin the installation process. By default X‑Plane will install to the Desktop. Though it can be installed elsewhere, it is strongly recommended that it be placed on the Desktop so that it can be found in the future. You can also install this app in Program Files folder (for example C:\Program Files (x86)\X-Plane 10\).After installing click the Start menu, then My Computer, then go to destination folder (C:\Program Files (x86)\X-Plane 10\) where you can find Aircraft folder to copy your downloaded aircraft. So the full path is for example C:\Program Files (x86)\X-Plane 10\Aircraft.
If you have Steam version, search in C:\Program Files (x86)\Steam\SteamApps\common folder.
