WidePSX 2.5.9 : FSX, P3D and MSFS Compatible Scenery Generator Bridge

[Jeroen Hoppenbrouwers]

It won't fix 1000 ft but the MSFS subscale is set to 29.91, not 92.
If you would fiddle the MSFS subscale to whatever is needed to match PSX, would that solve the problem from an ATC point of view? It's a gross hack but a) it keeps ATC happy for a while and b) if it reliably works, it gives a potential clue to how to solve this nasty issue. Assuming you have easy access to the MSFS controls, updating the altimeter setting to match PSX altitude is about the same dumb routine als moving HDG SEL a few degrees to match LNAV.

Hoppie,

flying at FL390 now and much closer to my destination. The FLs are now matching. I did fiddle wit the with altimeter settings to .92 vs. 91 (there was a minimal change).



I will be conducting more flights to see. However, this Beta version works pretty good vs. last version. Previous version, I would encounter significant differences in MSFS vs. PSX. And it all started due to update in MSFS.

Only solution that works for me, if there is a discrepancy, was to set "clear" weather. That way FLs match.

Sincerely,

[Jeroen Hoppenbrouwers]

But if you would turn the subscale away from 29.92 to that the MSFS altitude near-exactly matches the PSX indicated altitude, and keep doing this during the whole flight, would this make ATC happy? This is quite a crucial question.

Hello,

Thanks Andrej for your very detailed and helpful feedback. It confirms I went in the wrong direction. The problem is MSFS' QNH. First solution would be to modify this QNH to match PSX's one, but I'm not sure SimConnect allows this modification. Second, as Jeroen sugested (thanks Jeroen) would be to hack MSFS' QNH setting to force the aircraft flying at the right true altitude.

Now I need to find some time to investigate what's doable and implement if possible. Thanks again Andrej and Jeroen.

Best regards,
Jean-Philippe

Hello Jean-Philippe,

I will be testing tonight, what Hoppie suggested. I will keep you posted.
But thank you for your help and contribution.

Sincerely,

[andrej]

Hello Jean-Philippe,

starting a short flight to KBOS.

So far, I followed Hoppie's instruction and it seems (so far) that it works. I will advise later on.

Matching FLs during climb.


FL340 (do note that I updated Altimeter setting)

Thanks!

Hi Andrej,

That's a very complete and encouraging report. Thank you. So a "simple" hack of the MSFS' QNH may be the workaround. Very strange that MSFS is sending the PFD's altitude to clients, instead of the true altitude.

Question : when cruising at FL340, what was the QNH setting and altitude (in MSFS) BEFORE you changed the QNH ?

Best regards,
Jean-Philippe

Hello Jean-Philippe,

I did not take a note of that. However, I am step-climbing to FL360 and I will report.

I will check "current" altimeter, by pressing "B" and then change it to matching position.


EDIT:
Pressing "B" I get 29.92 in hg and FL356. On VATSIM Map it shows that I am at FL360.

I changed altimeter setting in PSX to 29.80 in hg, MSFS alt setting changed to 29.80 in hg and when I pressed "B", it shifted to 29.92 in hg.

Currently, at FL360 and at standard setting (29.92 in hg), and this is also reported on VATSIM Map.

EDIT2:
I noticed that even if I am playing around with the altimeter settings, the reported FL on VATSIM Map seems to be unaffected. I will investigate this further as I am over North Atlantic now.

EDIT3:
After while, the altimeter is reset back to previous setting. Seems like there is some override check / setting?

Cheers,

[andrej]

Apology to share so many messages, but my final update is a following.

Despite the fact that I manually adjusted altimeter settings in MSFS:


VATSIM Maps shows FL351

Hi Andrej,

Thanks again. After grabbing some informations about this issue, it seems the issue has been solved by the developer of vPilot.

Which version of vPilot are you using ? It seems version 3.3.0 solved the issue : https://forums.vatsim.net/topic/33024-vpilot-330-released/

Dear Jean-Philippe,

I am using vPilot version 3.4.6. If a fix is not possible, not to worry, there is always a work around (set "Clear" weather).

Cheers,

[JP59]

Hello,

Thanks to Andrej and Ross Carlson (vPilot developer) help, we have been able to fix the altitude disrepancy issue when flying online on VATSIM with the MSFS/PSX/WidePSX combo. Gentlemen, thanks again for your help and efforts. Nothing would have been possible without you. This fix is available via a user selectable option in the new WidePSX version. Please read the new user manual page 26 for informations on how this fix works.

Issues with external pushback tools have also been fixed.

Version 2.5.9 of WidePSX is now available. The download link has been updated in the first post of this thread. Enjoy !

Best regards,
Jean-Philippe

JP,

Very good spot on the VATSIM FL problem!

If you don't mind we will do the same in the PSX.NET Injector, at least all users of PSX will then be the same when online.

Cheers

Hi Gary,

Sure ! If I can be of any help, let me know.

Anyone experienced landing at UKBB and EGLL underneath the runway?

[BALDO]

Hello,

I can't get PSX to work with MSFS via WidePSX

I am using 3 PCs in a network: Two PCs have PSX installed, of which PC 192.168.1.101 is the PSX server.
On the third PC 192.168.1.65 is installed MSFS.
WidePSX is installed on the PC 192.168.1.65
I have also modified Simconnect file as indicated in the WidePSX documentation.
I am not getting a connection with Simconnect host IP and host port
WidePSX tells me that PSx is well connected.(green)
Maybe a problem with the MSFS port?
Can you help me? Thank you very much for your help.

Anyone experienced landing at UKBB and EGLL underneath the runway?

Sometimes, I get this error at various locations (it does not happen frequently, but seldomly it does happen). Eventually, this mismatched resets itself within a few seconds (but it does mess up my landing ).

I have EGLL from Inibuilds and have not encountered that particular issue (yet).

I can't get PSX to work with MSFS via WidePSX

Hello Jean-Claude,

whenever everything is setup properly and still there are issues with MSFS connection, I usually refer to SDK update. Hence, my question is, if you have the most recent version of MSFS SDK installed (IIRC it is ends with 9.13).

Thanks!

[BALDO]

Hello Andrej

Many thanks for your answer.
Yes I have the most recent version installed of SDK.

I try to modify port on simconnect.xml but it doesn't work.

[Victor126]

many thanks we made it, a question for Posky 747-400 aircraft models for MSFS, PSX and WidePSX, where can I find the active files...
