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

I'm getting an issue where there's an altitude mismatch between what PSX says and what the dummy plane in MSFS says (and that's what gets transmitted to Vatsim ATC I believe). Is there any workaround for this? I use the Asobo 748 as the dummy model.

The altitude reported by MSFS and the altitude shown in vPilot is a known issue.  It is related to the way MSFS calculates altitude as compared to P3d, FSX, and X-plane.   

The altitude fix will have to come from MSFS.

This happens to me on VATSIM as well. I am not 100%, but I believe that vpilot "corrected" this issue in one of its recent updates. But frankly, I am not 100% sure as I still encounter it.

Usually, I will advise ATC of this discrepancy, but if ATC still insists on a proper FL (i.e. if it is busy airspace for them), the I just use "clear weather" preset in the MSFS. This clears the issue and most of the time, but I do follow PSX weather. 

Once in descend, I turn on the live weather, as you get closer to the ground, altitude deviation subdues.

Hope this helps.

I am having a problem with the display of targets on my PSX NAV Display when using WidePSX in conjunction with RealTraffic.  The targets displays for approximately 2 seconds, disappears for about a second then reappears again in a continuous cycle.  When I use RealTraffic and PSX only, the targets display continuously (no cycling).  When I am not using RealTraffic, the vPilot targets show up without any issues. 

I am not trying to get the targets to show in P3d.

My normal setup is PSX, WidePSX, Active Sky, vPilot and P3dv5.3.

This usually happens when you have two sources injecting traffic into PSX. In your case probably WidePSX and RealTraffic. Try disabling traffic injection in WidePSX.

Hi Alex and Dirk.

Thank you for the reply.  it is much appreciated.  I will have a look further into it.

Is it possible to modify WidePSX so the weather from Active Sky can be used below FL200?

Below 20000ft the local weather provided by PSX is very accurate when its data is loaded from internet, and close to what AS could provide (they have pretty the same source). This modification will induce a complete rebuild of the weather module for a very small result, so I don't think I will consider your request, sorry.

Hello,

You may be aware of an altitude issue when flying online on VATSIM with MSFS. My understanding of this issue (Please forgive me if I'm wrong - I almost never use VATSIM -) is that due to the aircraft's true altitude changing in MSFS along the route, depending on the local QNH conditions, the VATSIM server, by receiving this true altitude, is leading to altitude alerts at the ATC side, even if you are all steady along the 1013 Hpa isobar at your side.

As the workaround seems to be impossible to implement at the VATSIM/MSFS side (at least at this time), I thought about a solution and decided to try a new feature in WidePSX. This feature will only be active above 20000ft. The principle is basically to apply an altitude correction offset to the MSFS' aircraft altitude before sending this data to MSFS. The value of the correction is related with the PSX's local QNH. As this local QNH may change along the route, by switching between the weather zones, the algorithm will smooth the altitude correction, avoiding any visual "jump" in MSFS. During my initial tests the MSFS' aircraft remains within a +30/-5 ft enveloppe from the target cruise altitude, even during extreme QNH conditions (970 to 1040 Hpa).

I decided to share a Beta version of WidePSX, including this new feature, in order to allow VATSIM users to test online and provide their feedback here. This Beta also includes a fix for the external pushback issue (tested with Ambitious Pilot's Pushback plugin in MSFS with success).

If you are interested by testing this Beta, please follow this procedure :

- Rename your actual WidePSX.jar file "WidePSX_backup.jar"
- Download the Beta .jar file here : https://www.dropbox.com/s/iu2hnyzzqcyn2t3/WidePSX.jar?dl=1
- Copy the downloaded file into your existing WidePSX folder
- Run WidePSX.jar and you should now see "WidePSX 2.5.8.1 (Beta)" as the application's window title

If you need to revert to the original 2.5.8 version :

- Delete the WidePSX.jar file in your WidePSX folder
- Rename the WidePSX_backup.jar file "WidePSX.jar" and run it. You should see "WidePSX 2.5.8" as the application's window title.

Best regards,
Jean-Philippe

Dear Jean-Philippe,

thanks for sharing beta with us. I would like to test it as I fly on VATSIM quite often, and my only trick is to clear the weather (in MSFS). That way, ATC reported altitude is in-line with the one that I am actually flying in.

I will try to report my initial findings tonight.

Cheers,
Andrej

Could you use the transition level from Qs392 to get the transition level as if ATC asks to maintain FL180, would there be a discrepancy or is this effect only amplified when you are cruising at the normal 747 levels?

Hello JP,

with the new widepsx.jar file I am unable to connect with the SimConnect Host...  (no "Connected" message)
As soon as I revert to the original widepsx.jar file (2.5.8) the connection establishes straight away.

That sounds like a good idea. I will see what I can do.

Strange. I didn't change anything related with the connection process. Please check the values in the WidePSX Network Tab before connection. Maybe a value has changed ?

Or a "smart" firewall does not allow the new .jar to connect.

Maybe. Checked this morning with the attached .jar file and procedure, no problem.

Hello Jean-Philippe,

I tested two flights and I am currently en-route. FL mismatch is minimal (e.g. PSX FL320, MSFS FL318, then it smoothly converges). In the climb, I recall seeing up to 300' difference, which again is much better then before (variance was significant).

Thank you for this update!

EDIT:
Today, towards the end of my longer flight, I was in FL380, but MSFS had me at FL370 (this was close to TOD).  Would sharing a SITU file help you in any way?

Sincerely, 
Andrej

Hi Andrej,

Thanks for your feedback. During my tests altitude remained within +30/-5ft so 300ft is not acceptable for me. I fear of not understanding the problem correctly (again, I almost never use VATSIM). My algorithm corrects altitude regarding PSX's QNH but I fear that the problem lies with MSFS' QNH. I need to investigate further and see if I can access this data through SimConnect.

Anyway, that's a first encouraging step. Don't hesitate to feedback your experience with online ATC, if they still complain (or not) that will be very appreciated.

Kind regards
Jean-Philippe

Hello Jean-Philippe,

just starting my flight from KFSO to EDDK and I initially climbed to FL330. MSFS shows FL320 (so there is 1000' discrepancy).



I will report once there is an update.

Thanks!
Andrej
