I am sorry Ray but I have no idea. Try asking on the P3D forums and include that AppHang event. There is a post on P3D appHang with v5, but it doesn't say much: https://www.avsim.com/forums/topic/602354-p3d-v52-freeze-application-hang/ Always worth updating your graphics card drivers, if you have not done so already...

Bvars are input events (as far as I am aware - or closely related). The latest release of FSUIPC7, 7.4.0, enables direct assignment to Input Events. Other than that, there is no direct access to B-type variables, and you cannot use them via calculator code. You can alter the xml files to allow b-var control via lvars, But I think that it would be better to look at the available Input Events before you consider this. There is a post somewhere where I showed how to do this. John

I have no idea how to do that. For windows defender, there should be logs/events for all activity in the windows event viewer - see https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/troubleshoot-microsoft-defender-antivirus?view=o365-worldwide This should tell you when a scan was started, finished, etc. Maybe next time you get a pause, cross-check with the events there, which should then tell you if this could be related to windows defender activity. Of course, if you use any other anti-virus software, you would need to check where that logs its activity.

Please see my previous response. You evidently do not understand the difference between the left and right hand sides of the axes assignment panel. You need to assign your axes on the left hand side, selecting Send Preset to FS, NOT on the right-hand side, which is for sending button assignments when entering/leaving ranges. These two things are completely different. Please see the provided documentation. And for ANY issues, please post here: That is the initial post, with solutions, for this issue. Post there if you have any further issues. I am also now locking this topic. John

Can you not log anti-virus protection behavior? That would give you more insight, if you think that this is the cause of such pauses/freezes. In a previous life, I used to investigate/trouble-shoot such problems for business apps, and the issue was invariably caused either by the OS not being tuned for its purpose, or from large-scale garbage collection. But this was in my unix / java days. Windows internals are more of a mystery to me that I would rather not enter into more detail than needed.... 😉

I am sorry you feel that way. I just don't understand why you would want to contact Hi-Fi when you have no information that your issue is at all related to AS. But do as you want.

Why are you creating a new post, rather than posting in the existing post for this issue? But why? Do you understand the difference between the left-hand side and the right-hand side of the axes assignment dialog? The left-hand side is where you assign to your axis, i.e. to send controls based upon the position of your axis lever which uses the value associated to the axis lever position. The right-hand side is to send specific controls when the axis lever enters or leaves a specific range (this side to send button controls) , but the value of the axis lever position is not used. Please at least read the provided documentation if you do not understand the UI, it is explained there.... What you need to do is to use the presets as given in the other post, and assign to the axis using the left-hand side of the axes assignment dialog, selecting Send Preset to FS. I am closing/locking this now. Please use the original thread for any more questions using these presets:

But why report to Damian/Hi-Fi as it could be nothing to do with AS? As a developer. it is very annoying when people keep pointing the finger at your software as the culprit for some strange issue that is not at all related to the software that you provide. I get this all the time, and it is very frustrating as well as being quite time consuming. My suspicion is that it is either windows or P3D, but with these types of issues it is incredibly difficult to determine the cause, and quite often they disappear as easily as they appear. I has an issue last year that caused my flight sim PC to pause for several minutes, and then my system was auto-rebooted, with no logs or errors reported anywhere. This lasted for 6 months without resolution. I don't have this problem anymore, but I suspect it was a GC card/driver issue.

These tables have been showing the correct information for 15+ years. The logic that populates the tables is not a problem, at least with P3Dv1-5. I have not checked for any changes in AI data for v6. Maybe there have been some changes since the P3Dv6 release, I do not know. I need time to investigate this, which I do not have until January now, at the earliest. It is not possible. Please give me time to look into this. i will respond again when I have time to investigate, and not before. Please be patient. John

I don't think weather updates can cause such long pauses. I haven't used AS in quite a while now, but can't you also log weather updates? You could check the AS logs to see if any updates are in progress when you get this freeze. Sim pauses/freezes are and have always been an ongoing issue in all sims. I can only look to check that this is not caused by FSUIPC, I cannot really help in tracking down other causes, I am just too busy and don't have the time for this. Cheers, John

The message is displayed in the window but you will only see it if/when you open the FSUIPC7 main window, by Alt+F or any other means. I guess I could automatically open the window if an update is available - I can look into adding this for the next release. John

No, I cannot see how it could be an issue.

Yes I have, and in fact this was implemented and released in version 7.3.23: This is what it looks like: If you are not seeing that, check your FSUIPC7.log file for a message of the form: **** GetLatestRelease: Error ... It may be that anti-virus software is blocking the call to get the current release number, so check any anti-virus software that you are using and allow the http request to get the needed information. John

Not really.... I don't have time to check the AI tables (yet again...) at the moment. I can take a look in the new year, For now, you can try logging AI data to see if that helps you. Add the following to the [General] section of your FSUIPC ini file: Debug=Please LogExtras=x50000 You can also try the TrafficLook program, which should should be similar to what you are developing, available from You can also search this forum for other issues reported on the AI traffic tables, maybe they will help. What version of P3D / FSUIPC are you using? John

Ok, let me know how it goes. But why would you expect to find any of these, especially in a successful flight? When you get a pause, I doubt very much that it is to do with having those events being sent....!

No problem - thanks for the update. John

Are you using the FSUIPC PFC driver (PFCcom64.dll)? Logging of events and axis controls may give an indication of why this is happening...or the PFC logging option 'log all axis details'. If you want to try the registered/licensed version of FSUIPC7, I can send you a trial license (see topic pinned to the top of this sub-forum). What help do you need? Just try it, consult the provided documentation, and check these forums for any similar issues if you have a problem. If you cannot find a solution, post again here and I will try to help. But please be aware that I have never set-up/configured or used any PFC devices... John

That logs to the FSUIPC6.log file. The simconnect log is a different log, which will log all simconnect activity, i.e. for all apps/processes that use SimConnect. To activate this log, see I can't see how that could affect anything.

Yes, very strange. You could try logging all simconnect data, to see if that is still being received when you get this pause/hang, or what the last data was. The LogExtras value for that is x400. The log file can/will get pretty large with this though. Also maybe event logging. Did you check for any windows events (in the Event Viewer) around the time this occurred?

Can you please try the attached version - this should allow those helicopter-specific axes to be calibrated, with the mapping to aircraft axes as shown above. Note that you still have to assign with 'Send as normal FS control', and not with 'Send direct to FSUIPC calibration'. John FSUIPC7.exe

Is the lock-up at the same time as the EFB disconnect from FSUIPC: ? Why is the EFB disconnecting from FSUIPC? Is this because the EFB thinks the sim or FSUIPC has stopped (due to the pause/lockup)? If the sim time didn't change, then the FS certainly froze during that period, However, as FSUUIPC didn't try and re-connect (or log a data stalled message), it must either have been still receiving data, or, more likely, it was also stalled/locked up. That is also worrying - do you know what was using all those cores? Have you checked for any windows events around the time of the pause? Sorry Ray, but I don't know what to advise. I certainly don't think this is anything to do with FSUIPC. Maybe check the P3D or AVSim forums for similar issues.

Why don't you try reading the this thread that you posted in, and you will find that you need to install the FSUIPC Go-Flight driver (dll). All the information you need is already in this thread.

I think the issue is that you need to click Confirm before you click OK, otherwise the offset and parameter are not read. However, there is still an issue as the key release is also being set when empty. I have corrected this in the attached version if you could try it. John FSUIPC7.exe
