Mission-X

Mission-X is an X-Plane plugin designed to create and manage various flight missions for both helicopters and planes. It allows users to generate random missions based on community-shared templates, pre-defined scenarios, or personal flight plans sourced from platforms like Simbrief and flightplandatabase.com. The plugin includes tools for mission customization and interaction with other libraries to enhance the mission experience. Compatible with X-Plane 11 and 12, it also supports the addition of custom scenery for improved mission context.

Introduction

Mission-X is an X-Plane plugin that can help in:

  • Generate Random Missions for Helicopters and Planes a like.
    Supports overpass based templates to generate medevac missions (Community example can be found on @daikan github page)
  • Run pre-defined missions that were shared by other community members (example in x-plane.org site or maybe even in the current site).
  • Provide a framework to build your own adventures (You can use other missions as a template and build on it, simple editor will do the trick).
  • Generate ILS missions: place your plane in an airport and search for other ILS airports around. It is a simple, one leg mission, but at least you can generate a quick ILS flight to train, meaning, you will have to prepare the whole flight/charts weather etc..., the plugin will only provide you with a destination ramp/terminal.
  • Generate missions based on "flightplandatabase.com"  and "Simbried": You can now prepare a missiong based on your Simbrief flight plan, or using a pre-defined route from "flightplandatabase" site.
  • Convert flight plan from LittleNavMap to mission files and then use it as a base for your own mission pack by expanding it to make it more engaging. 

The plugin is evolving all the time and run best on X-Plane 12, although it is also compatible with X-Plane 11.

For best results, you should also download "custom scenery library" files like:

CDB: https://forums.x-plane.org/index.php?/files/file/27907-cdb-library/
RuScenery: http://ruscenery.x-air.ru/
Handy Objects: https://forums.x-plane.org/index.php?/files/file/24261-the-handy-objects-library/

My site can be found in: "http://snagardev.weebly.com/", you can get a cross platform java based installer for the plugin, unfortunately it is not compatible with this site rules (but you can get it from the plugin page).

 

Installation


The plugin is compressed in ".7z" format.
1. Place the file in "{X-Plane}/Resource/plugins" folder.

2. Extract the compressed plugin file.

Plugin folder structure should look something similar to:

missionx 
├── db 
├── docs 
│   └── license 
├── libs 
│   ├── 64 
│   ├── bitmap 
│   ├── fonts 
│   ├── sqlite 
│   └── text_to_speech-google 
├── lin_x64 
├── mac_x64 
├── save 
├── templates (pre-defined random mission templates)
└── win_x64
 

3. Since v24.06.1 the "Random Scenery Pack" is bundled with the plugin, so you can find it in the "plugins" root folder and follow the following steps:
    3.1 Create folder by the name "missionx" in "{XP}/Custom Scenery"
    3.2 Save the file in "{XP}/Custom Scenery/missionx"
    3.3 Extract the file (a new folder by the name "random" will be created).

X-Plane
├── Custom Scenery 
│   └── missionx
│        └── random

 

The Random Scenery pack is mandatory to generate random missions. This will be the folder it will write its mission file and overrite it every new random mission is created.

4. MacOS users only, post installation steps (if not already done before):

======================================================
=== Troubleshooting Library issues on MacOS
======================================================
The latest build uses the OS cURL shared library, so there is no need to use the custom build I provided for this specific library.

If you still have issues, please use "otool", if it is installed, you should run the following command from {xp} installation folder:
$ cd {X-Plane root folder}   (installation folder)
$ otool -L Resources/plugins/missionx/64/mac.xpl

 

Troubleshooting

Linux and OSX troubleshoot information can be found in the README.txt file at the root folder of the plugin, it explains how to fix missing libraries in OSX and Linux.

For any issues/suggestions you can contact me at: "[email protected]"

Changelog

  • v26.09.2 09. Sep 2026
    . [ui] Added more llm options in most of the screens. This is an opt-in feature.
    . [ui] Better support for special UTF characters that can also be presented in ascii table.
    . [ui] Mission description will be visible in most screens after mission generation. It can be hidden.
    . [llm] Continue optimization of the instructions to the llm.
    . [random pack] Plugin will create the "missionx/random" in "custom scenery" folder if the folder is not present.
  • v26.09.1 01. Sep 2026
    . [bug] Fixed regression where mission creation screen did not construct a valid mission for flight plan with only one leg.
    . [llm] Added an "opt-in" option that uses the llm to pick a target while constructing a user based mission.
    This is a work in progress and highly dependent on chosen model and machine capabilities.
    Currently, the success rate is lower than I would like to have, but I have implemented a fallback logic to produce plausible locations.
    After doing some more tests, I think it is safe to use the "GPU Offload" option, but prefer to uncheck the "Offload KV Cache to GPU Memory".
    . [llm] updated the llm doc, to reflect how we treat the "GPU offload" settings. Previously suggested not to use it, but currently I think it is safer.
  • v26.08.2 29. Aug 2026
    . [win Error 127] Statically linked cURL in Windows plugin.
    . [ui] Added mono font.

@dylanWagner After installation, I suggest using "SkunkCrafts" utility to update the "random scenery pack" to the latest version.

@dylanWagner The error you receive means that you failed to add the "{xp12}/Custom Scenery/missionx/random" folder part. Please follow the "installation" guide above, "check step 3", it explains how to create it, step by step.

Guten Tag Ich habe die beiden Hauptdateien und alle zugehörigen benutzerdefinierten Szenerien in meinen X-Plane 12-Ordner für benutzerdefinierte Szenerien installiert. Das Plugin läuft, aber beim Generieren/Erstellen einer Medevac-Mission erscheint die Fehlermeldung „Fehlercode beim Schreiben: Datei konnte nicht zum Schreiben geöffnet werden - (Routing der random.xml-Datei)“, gefolgt von der Fehlermeldung: „Möglicherweise fehlen 3D-Dateien“. Könnten Sie mir bitte zeigen, wie ich das beheben kann? Danke!

Hey there,

I installed the main two files and all supporting custom scenery to my custom scenery xplane 12 folder. The plugin runs, but when i come to generate/create medevac mission it shows an error "Error code while writing error: unable to open file for writing - (random.xml file routing) followed by this error message: "There might be missing 3d files".

I'm very eager to try your work and give you feedback. Kindly show me how to fix this?

Thanks!

I can't quite seem to get this working 100%. It doesn't upload co-ordinates to my gps. Also, it asked me to hover over the scene for 14 seconds and I did for like 2 minutes at different heights, etc and nothing happened.
