• 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.

ADE is essentially freeware. It is not open source. The difference is that ADE is available as an application at no charge (see below for ProKey and Commercial Use). The source code is not available and you cannot distribute any part of ADE without our permissions. All copyrights remain with us or the respective copyright owners of the components we use.

There are parts of ADE that can be paid for. The ProKey is a small piece of code that allows you to use some advanced features. you do not need to the ProKey to successfully create or modify airports and scenery. However the ProKey features can make the job easier. Currently the ProKey can be tried out for 15 days. Thereafter you need to purchase a license (currently $9.99)

If you plan to use ADE for financial gain then it is not free to use and you will need a commercial license. Financial gain means that you are making something with ADE that you plan to sell or that an organisation that you are doing the work for plans to sell.

Please contact us if you are using or plan to use ADE in this way.
