• 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.

P3D v5 Manifold pressure gauge

Good evening everyone,
I need your expertise for a moment...
I’m currently working on animating a manifold pressure gauge, but I’ve run into a problem.


I’ve set the keyframes to 0, 10, 15, 20, 25, 30, 35, 40, 45, 50 (the instrument scale goes from 10 to 50 inHG) and adjusted the needle rotation (Z rot) in the instrument accordingly.
The animation is defined in the MCX as needle_manifold.


Now, in the simulator I’m getting the following issue:
At 100% throttle, the needle rises only up to 29.92 inHG (which theoretically corresponds to ambient pressure). The RPM needle correctly shows 2500 RPM.
However, I expected the manifold gauge to show 44 inHG at full throttle.


If I change the Aircraft.cfg and increase max_design_mp to something higher than 44 — for example, max_design_mp = 60 — then the needle does move slightly above 29.92, to around 35 or 40 inHG, but never reaches the defined 60 inHG (or in my case, the maximum 50 inHG on the instrument scale).


In the Aircraft.cfg, the parameters are currently set as follows:

max_design_mp = 44
min_design_mp = 5
max_rated_rpm = 2500.00


What am I doing wrong, or where is my thinking error?
 
It sounds like you've just run foul of one of those bugs left over from FS2K-something. Go to the aircraft.cfg file and under the [piston engine] section, set turbocharged = 1. If I'm right, that should fix it.
 
Good evening everyone,
I've noticed another problem while continuing to build.

When I turn off the engine, the gauge should display atmospheric pressure (29.92 inches/Hg), right?
-Mine is showing around 20 inches/Hg.

Does anyone have a solution for this?

Thanks a lot.
