• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 Improving the Cessna 208B Caravan systems realism (MSFS 2020)

Hello everyone,


I’m working on a personal project to improve the Cessna 208B Grand Caravan in MSFS 2020.
I have real-world flying experience on this aircraft, and my goal is to progressively make the sim version behave closer to the real one in terms of systems logic and failure modes.


At the moment, I’ve been experimenting with XML/L:Vars to introduce more realism, but I’d like to go further with features such as:


  • A working icing annunciator light (blue light as in the real aircraft).
  • An aural warning when fuel tank selectors are closed while the engine is running.
  • Basic failure logic for oil, fuel, electrical and hot start, ideally tied to the aircraft’s POH.
  • In the future, perhaps a small EFB-style tablet to monitor oil quantity/consumption and system state.

The idea is to gradually build a “study-level” Caravan by adding realistic behaviors and alerts, always based on the aircraft’s manual and real-world operation.


I’m still learning the MSFS development ecosystem (ModelBehaviors, HTML/JS gauges, WASM, etc.), and I’d love to hear from more experienced developers:


  • What’s the recommended way to integrate these kinds of logic (XML vs. WASM modules vs. custom HTML/JS gauges)?
  • Has anyone already tackled things like oil consumption, icing lights, or fuel selector warnings?
  • Would anyone be interested in collaborating, testing, or guiding me on best practices?

Any tips, references, or sample code would be greatly appreciated. My intention is to keep this project open and share progress with the community.


Thanks in advance!
