• 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.

    The best way to build in engine failures is with some XML gauges. They can even be hidden. By default, FS plane engines don't fail. -Pv-

    Keep in mind there is more to "spool" than 1505 depending on what you are looking at (CN2 by itself or throttle vs thrust.) A reference document earlier in this thread claims 1507 is some sort of engine RAM drag or airflow. To me, drag most appropriately slows something down given the same fuel...

    ^^^ This is pretty much how I use and interpret it. Only diff is in my experience, the starter spool is also affected. I'll take a look at it again some day. -Pv-

    I have not seen any indication through usage over the past 15 years that 1505 is anything other than spool rate in practical usage. Whether this is some kind of C2/FF/bleed calculation may remain unclear and depending on how you interpret the numbers theoretically, you can get varied...
