• 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 v4 Brake system incompatibility FSX-P3D(v4)

In case your ever stumble onto the same problem I did (when debugging why a XML gauge that worked in FSX, didn't work in P3Dv4):

In FSX, when you set the Parking Brakes, the Avars for left/right brakes will allways indicate full brake pressure too.
So: when (A:BRAKE PARKING POSITION,bool) is True, (A:BRAKE LEFT POSITION,percent) and (A:BRAKE RIGHT POSITION,percent) will ALLWAYS be 100%.
(assuming that in the ContactPoints the left/right brakes are assigned to the main left resp. right main wheels, which is usual)

In P3D(v4) however, the ParkingBrakes and normal brakes appear to have be made independant.
So: when (A:BRAKE PARKING POSITION,bool) is True, (A:BRAKE LEFT POSITION,percent) and (A:BRAKE RIGHT POSITION,percent) will be 0% (if you don't apply normal brakes).

No doubt the implementation in P3D is better then in FS9/FSX .
But just be aware of this difference.

Good to know. Actually most parking brakes in the past were just the regular brakes held down, but I don't know about the modern electric jets. So FS9/FSX would be more accurate for the earlier planes, while P3D may be more accurate for the later ones?
 
I have also noticed that the park brake is much less effective than the regular brakes and if you open the throttle about half way the park brakes disengage and you go visiting interesting places
