• 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.

Cruise table

I would like to be able to fly with the cruise tables and then fly in level flight at constant altitude and at constant speed.
To do this the mechanics of the flight tells me: Tn = D, where Tn and the necessary push and D and resist it on the cruise.
In the cruise tables the value of N1 is present. So I just have to calculate the relative CN1 and then go to work on table 1506 in the .air file.
The problem is how can I calculate the resistance of the aircraft in FSX?
 
the same as you would anywhere. coefficient of drag after adding induced drag, parasite drag, and all other drag together. CDqS gives the thrust you need at cruise.
 
The easiest way to see what drag you have is to use Air Wrench or AirWiz. That will give you total drag for any cruise flight condition. It will also tell you your thrust against CN1,

What's the name of that tool that can show you live coefficients? I've used it but forget the name.....great tool for this stuff. It takes all the FS airfile data and converts it correctly into coefficients the sim is using.
