# DA62 Mod The `DA62 Mod` airplane sample can be downloaded from the [Help](../../../devmode/menus/help/) menu in DevMode. This sample contains only a few files that are used to modify an existing modular aircraft (in this case the [DA62](da62/)). The purpose of this project is to show how you can mod (or "patch") existing modular aircraft with additional files.     ### Loading And Building The Project In order to load and build the project in Microsoft Flight Simulator 2024, you must have previously enabled Developer Mode ([see here](../../../introduction/sdk-overview/) for more information). Once enabled, simply follow these steps:   - Use the **Open project...** command from the [**File**](../../../devmode/developer-mode/) menu. ![Developer Mode Open Project](images/7_Samples_Tutorials/general_openproject.png)   - Select the file `DA62_Mod_Project.xml` from the `DA62_Mod` sample project. ![DA62 Mod Project Directory](images/7_Samples_Tutorials/Samples/Aircraft/DA62_Mod/da62mod_1_xml.png)   - The **Project Editor** should open automatically and show you the project `mycompany-aircraft-da62-mod` (if the Project Editor doesn't open, then you can open it from the Developer Mode [**Tools** menu](../../../devmode/menus/tools/)) ![The DA62 Mod Package In The Project Editor](images/7_Samples_Tutorials/Samples/Aircraft/DA62_Mod/da62mod_2_project.png)   - Once the project is loaded, you can **right-click** on it, and select the *Build and Mount* option. This should be done while on the *main Menu* of the simulation: {{< image-center src="images/7_Samples_Tutorials/Samples/Aircraft/DA62_Mod/da62mod_3_build.png" alt="Building The LFPG Package" >}}   - This will build a package from the files specified in your project. This package will be named `da62-sdk-aircraft` and will be output in the **Packages** folder created in the same directory as `DA62-SDK-Project.xml`:   - Building the package will also install it into Microsoft Flight Simulator 2024 and so you should now proceed to the aircraft selection screen, search for the DA62 aircraft (the official version, not the SDK version), and select the option to **Configure** the aircraft. In the configuration options you will now see a new **Da62 Passengers SDK Mod** variation: {{< image-center src="images/7_Samples_Tutorials/Samples/Aircraft/DA62_Mod/da62mod_4_variant.png" alt="The DA62 In Microsoft Flight Simulator" >}}
