I had the same problem after updating to Win 11 24H2 in early December. A search revealed the solution which John has shown above. I also had problems with my two GoFlight GF166 displays. Windows recognised them but the displays remained blank. A uninstall and reinstall of the original GoFlight software resolved the problem. My saved profiles were unaffected. Problems but far fewer than with the new MSFS which would drive me bonkers. I prefer the stability of P3Dv5. 😊 Happy New Year John!

@John Dowson, very informative and congratulations to @Soundman1 for his efforts.

That’s my conclusion too.

@John Dowson, this is a strange problem because I’m running a very similar setup to Jon. The main difference is I run AiCompanion on a WideFS laptop and RC on a second WideFS desktop. No problems whatsoever despite Ai being set at 100% with 230+ Ai at a very busy Heathrow. I also use PMDG 777 but not QW787. Would site of my FSUIPC6.ini help?

Thanks John. Been a long time since I used that option. Hopefully he’s reading your replies here

Hi John, Thanks for your post. I should add I'm running the same version of P3D v5.3 and also have the PMDG 777 and use AIG Ai aircraft at 100%. So my setup is very similar to Jon's bar the QW787 which I don't have. I have never had this problem in RC4. I have already asked him on the RC forum to check is extra logging is occuring. Although it shouldn't cause any problems it does prevent you or me analysing the log. Is searching for Debug=Please the best way to find logging?

Hi @John Dowson, I referred Jon to here as it was an FSUIPC error being reported. Jon is advising he can't upload a FSUIPC log as it's 400Mb+ That suggests logging is being enabled. Could that cause a problem in a long flight?

@Carob, do yourself and your father a favour and ditch FS9 / FS2004. Buy P3Dv5 (not 6) for around 50GBP. I have several GoFlight units - MCP Pro, EFIS, T8, P8 , GF166 and a LGT. All nearly 20 years old and working perfectly with Windows 11. Firstly, they must be connected to USB2 ports. USB3 are meant to be backward compatible but it can be unreliable. Modern motherboards don’t have USB2 ports but they do have USB2 headers. I bought this from Amazon. Xiatiaosann 2 Pack 2 Port USB 2.0 Rear Panel Expansion Bracket. It connects to USB2 Header on my mobo. Then I bought a powered USB2 hub (backward compatible USB3) should be okay. Plug your GoFlight units into the hub that’s plugged into one of the ports on the expansion bracket. All my units work perfectly. And the scenery is transformed in P3Dv5. Get an Academic Licence. That’s fine. I hope you read this and haven’t given up. I also use the Pollypot software which has a bit of a learning curve but is very good.

No it doesn't. Thanks. Just some left over entry from before. I've updated to 6.2.1 and taken your advice to edit aircraft profiles. Much neater. Thanks. 😁

Hi John, I'm still getting U=<< MISSING JOYSTICK >> in my ini file. I've checked it but I'm struggling to find the wrong entries. It's attached. Any help gratefully appreciated. FSUIPC6.ini

Finger problems! 😄

I've discovered the problem. Two opening brackets! 🙄 Amended and all is now well.

Hi John, I've been assigning letters to devices for years but this problem has me beat. I have CH Pro Pedals as P; Fulcrum One Yoke as Y and Fulcrum One Throttle Quadrant as T. The first two are fine. The TQ keeps showing as MISSING even though the entries in the csv file seem fine. Can you throw some light on the problem please? The reason for the duplicate messages is because I changed the order thinking that might solve it. It didn't. Ray_FSUIPC.zip

But it has occurred with shallower descents. My eyes aren’t deceiving me, honest. 😁 Thanks for your insight John. Have a well deserved break. 👍

Hi John, I had two flights today and in neither did the pitch calculations misbehave. I’ll try with a different aircraft tomorrow but given you’re busy with MSFS I won’t take up any more of your time. Thanks.
