• 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.

    Hello. I'm making a utility in VS2019 C# that shows a flat Garmin G1000 panel on a tablet, which interfaces to a SimConnect client on the computer running FS2020. Idea is to have a solution for the finicky controls trying to click and turn the knobs while flying which is a bit of a PITA. First...

    New SimConnect API for C#

    [If the below feels like I am a "Grumpy old man" then please humor me. 57 years and developing since before the 8086 and 8088 came around should entitle me to that. I still have the TRS-80 version of Flight Simulator somewhere, if the floppy is still readable] I am a reasonably experienced...

    Attempting to set RECIP ENG MANIFOLD PRESSURE:1 , but it simply is not setting, even though the debug cout<< is running I can see that the SimConnect_SetDataOnSimObject function is working, so the problem has to be from another part of the code no? If someone can help me find the issue that...

    Hello, How does one create an AI simobject in the AWAKE state vs in the SLEEP state? I am working with some code that successfully creates a simobject using the SimConnect_AICreateNonATCAircraft function but it appears to create it in a SLEEP state. This simobject is a missile, not an aircraft...

    Hello everybody, before asking my question, please let me introduce my topic a little. The upcoming release of the mumble 1.4.0 VOIP software will (most probably) include a new plugin-framework. I developed such a plugin featuring simulation of radio comms. In essence it allows everyone to...

    Currently, I am using the "GENERAL ENG THROTTLE LEVER POSITION:1" variable to get the amount of throttle being used in the CJ4 but the SimConnect values are different than what is displayed in the cockpit. The CJ4 is showing 77.1 in the cockpit (Working-Title-Mod) and the value I am getting...

    Hello everyone, I wanted to ask some of you who program, if it is possible to show the simulation speed variable, SIMULATION RATE, through a number that appears on a form outside the simulator scene, a line of text on a small form that can be launched at will and that connects to the MSFS2020.
