Autoflight problem PMDG after installing FSUIPC4

MOVED FROM FAQ ("frequently asked questions") SUBFORUM!

 

Hello there Pete,

 

I recently acquired FSUIPC4 (the payware version) and ever since that installation my PMDG aircraft (737 NGX, 777 LRX) are experiencing Autoflight issues. LNAV and VNAV, AT and LVL CHG are not responding to whatever is programmed into the FMC. The speed indication on the PFD roughly follows the speed entered into the speedwindow. When I then open up Addons in the FSX taskbar and subsequently open the FSUIPC interface and press: Normal defaults everything responds normally again. Now it is nice to know that there is a cure to my problem, but what causes it? I don't want to have to stop the flight every time I depart from an airport to open up FSUIPC to press Normal defaults.

Simulator: FSX Gold SP2

FSUIPC version: 4.959

Cheers, Marc

I've had to move this into the support forum, which is where support is provided. Please do not post support questions into the reference subforums.

As you found by setting normal defaults, FSUIPC itself does not interfere with anything your aircraft is doing. So something you are setting is the problem.

That button changes some of the the settings (mostly those on the Miscellaneous tab) which are saved and used thereafter all the time until you change them again. Just press OK to exit the options when you've pressed it, and it is saved. The settings go into your FSUIPC4.INI file which is loaded each time you run FS.

I don't use any PMDG aircraft and I don't know what option(s) you selected which your addons didn't like.

However, I have to say that there really is nothing FSUIPC can do to prevent LNAV, VNAV, AT and LVL CHG operations.  The worse you might have done is set reversed trim and zero elevator options on the miscellaneous page.

Why not just be careful what you select and only use the settings you need and understand?

Thank you for your reply Pete.

 

I just completed a flight from Vienna to Milan in the PMDG 737-900 NGX and everything seemed to work fine now. After I had posted my previous post I looked into the Introduction manual that accompanies the 737 NGX in which PMDG states that they have found that in extremely rare circumstances, users with FSUIPC installed would need to delete
their FSUIPC.ini file after installing the PMDG 737NGX and allow it to regenerate.

That is what I have done and apparently it did work. It might have been caused by an update that was recently added to the 737 NGX software.

 

kind regards,
