• 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.

Hydraulic System simulation

Hi everybody,

I am new in this foro but I would like to start asking you a difficult question.

I am trying to modify a merge concerning the speed of hydraulic pressure decrease when you put the Hydraulics pumps to OFF, I mean, I use an A320 merge and the problem is that when you switch off the pumps, the hydraulic pressure drop very very slowly (takes almost 3 minutes to become 0 psi).

I would like to create a gauge or to modify the file .air in order to acelerate this drop but I am touching every parameter in the file .air and nothing happens.

Please, could you help me?

Thanks in advance

Foreto
 
Don't know any of that but in the aircraft.cfg file there's this section

I guess you're talking about the "max/static compression ratio". Change that. I think a value smaller than 1 is slow compression and a value bigger than 1 is fast compression.
 
There is no link between the max and normal compression and the hydraulic system (as far as I know)

Thanks for your help

I mean, I am looking for the way to change the time to depressurise the system ones that you have selected the hydraulic pump off (because it takes almost 3 minutes now)
 
3 minutes is still very fast for hydraulic system.
Back in the day, after the day's flying was over, we could trot into the hanger the following morning and there was still enough hydraulic power to open the canopy.
