This topic demonstrates how to add an aircraft addon to Flight Simulator X using Addit! Pro For Flight Simulator X by working step-by-step through the installation of an actual, downloadable aircraft addon. This complete walkthrough teaches you how to install an aircraft to a folder of your choice, assign aircraft and panel pictures, configure installation options, review reports and verify the results.
Our aircraft addon is called Cessna L-19 Bird Dog by Massimo Taccoli, D.G. Seeley, Dennis Seeley, Chris Coarse.

The first step is very easy, begin by opening Addit! Pro. Pull down the File menu as shown below then select Install an Addon:

When the Addon Installation Wizard window appears, press Select Addon Files:

When the Select Addon Files window appears, locate l19d_fsx.zip. That is the file you downloaded above. Select only this zip file. Make sure all of the files inside the zip file are selected in the Zip File list, as shown below. Press OK:

Back on the Addon Installation Wizard window, all colored status indicators are either green or yellow so you could press Finish at this point and install the addon using the default configuration. Instead, we will tweak the configuration to demonstrate how you can customize the installation process. Press Configure Aircraft:

On the Configure Aircraft window, click the small Quick Picks button as shown below to bring up a list of some potential installation folders. The item Cessna L-19D seems most fitting so pick that one. Press Yes when asked about applying your selection to all aircraft. You do not have to use a Quick Picks folder. To make a new folder for the aircraft, click Change Folder instead. To tweak just the category, press Change Category. Press Next to continue:

On the Configure Aircraft window, position to the Set Picture step by clicking Next or Previous. Press Set Picture then select a picture to represent the aircraft variant. With this addon, a picture is pre-selected for you, so you can keep it or pick a different picture.
This aircraft package includes two variants of the Bird Dog. Assign a picture to each variant as shown below. Keep in mind you can always assign (or reassign) a picture later on using the Edit Aircraft window. Press OK to continue:

Back on the Addon Installation Wizard window, Press Configure Panel:

On the Configure Panel window, where it says "Install the panel files for 'Panel 1' to", keep the default value "The folders determined by Addit! Pro". Press Next:

On the Configure Panel window, position to the Set Picture step by pressing Next or Previous. Press Set Picture and select a picture to represent the panel. Press OK:

Back on the Addon Installation Wizard window, we will accept the defaults for the Sound and Other steps, skipping past them. The step indicators are yellow, so the default values should work just fine. Press Installation Options:

On the Set Installation Options window, enter an addon name. The Quick Picks button to the right provides a handy list of possible names. Optionally, identify the authors and provide a description as shown below. Press OK:

Back on the Addon Installation Wizard window, press Installation Summary and review the choices:

Tip: maximize this window to see as much information as possible. Everything looks to be in order. Press OK:

On the Addon Installation Wizard window, press Finish to complete the installation:

According to the Installation Results report, all files were correctly installed. Press OK to dismiss the report window.

Use Addit! Pro's Edit Aircraft window to verify the new aircraft. Press the Edit Aircraft button on Addit! Pro's button bar. When the Edit Aircraft window appears, position to Cessna TO-1D US ARMY. Click the Report tab. Here we see a minor configuration issue but nothing that will seriously impact performance or functionality:

Finally, start Flight Simulator and select your new Cessna L-19 Bird Dog aircraft and enjoy!
