Problem: Where are the manuals?



Please read the manuals!

Everything you need is in the manuals 🙂


Problem: It's just not working right. 🙂

Solution: A very comprehensive LOG file is available to assist in troubleshooting.

It's located in:

C:\Users\****YOUR USER NAME**** \AppData\Roaming\Ultimate Ground Crew X\

Please post a link to it in your thread.
Also, read the other posts below for ideas.



Problem:  While using FSX, I get an error message on loading FSX that FSX has detected a problem with UGCX32.dll.

Solution: This is because something caused an error in a previous load of Flight Simulator and Windows decided to intervene and permanently mark that DLL as unsafe. You need to run "regedit", find the registry setting for

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

and in there, edit the entry for fsx.exe to REMOVE any mentions of

Data = $IgnoreFreeLibrary<UGCX32.dll>

Then, restart FSX - you'll get the error message once again, but click Yes, and the application will work correctly this time.

Also, make sure your FSX is running as Administrator.



Problem: UGCX does not appear in the ADDONS MENU in FSX or P3D 

Solution: You forgot to ACTIVATE UGCX via the UGCX Config Manager, or your DLL.xml file is corrupt.

Do not forget to click directly on "SUBMIT DETAILS".




Problem: I activated UGCX via the UGCX Config Manager, but UGCX still does not appear in the ADDONS MENU.

Solution: Your DLL.XML is likely corrupt.  The DLL.xml is a very sensitive document and if there's anything wrong with it, addons like UGCX will not load.

Side note: If using FSX, also ensure you have the latest version of FSX installed (FSX + Acceleration /SP2)

What to do:

1. Backup your pre-existing DLL.xml (located described below).

2. Download our DLL.xml to test.

3. Overwrite your current DLL.xml with our test dll.xml.

DLL.xml locations:

C:\Users\***your user name***\AppData\Roaming\Microsoft\FSX\dll.xml

P3D V4 and v5
C:\ProgramData\Lockheed Martin\Prepar3D v4\dll.xml

C:\ProgramData\Lockheed Martin\Prepar3D v5\dll.xml

You can open the DLL.xml with Notepad.


If interested, PMDG has written a great article on the DLL.xml and how to fix them!



Problem: Where is the UGCX Config Manager?

Solution: It's on your desktop (Yellow Checkerboard Icon) or via the Ultimate Ground Crew X Folder in the START MENU.



Problem: I've created a CUSTOM PUSHBACK ROUTE, but it's not working properly.

Solution: You forgot to select the PUSHBACK POINTRight click on the 2nd to last way point (the grey dot), and select PUSHBACK POINT.


Problem: The Majestic Dash 8 won't move when pushed back.

Solution: The Dash 8 is now supported as of Version 2.0 released on May 30th, 2020.


Problem: I made custom routes.  I want to share them.  What do I do?

Solution: Your custom routes are located here.  They are stored under the airport's ICAO name.

C:\Users\****YOUR USER NAME****\AppData\Roaming\Ultimate Ground Crew X\Airport Profiles\


Problem: I can't see the ramp agent under the nose of my plane.

Solution: You can adjust the Ramp Agent's position via the POINT OF VIEW (POV) slider in the AIRCRAFT PROFILE menu.


Problem: Are there any issues using UGCX Voice Control with FS2Crew Voice Control?

Solution: If using FS2Crew Voice Control, put FS2Crew in HARD MUTE MODE via the button on the FS2Crew Main Panel while issuing any voice commands that are the same as those used by UGCX. This way you won't trigger both ramp agents.  We'll have to update the FS2Crew's to handle this without requiring you to turn on Hard Mute when talking to the ramp agents.

Also, except for the FS Labs Airbus, all FS2Crew Voice products must use ENGLISH US for the speech recognizer settings.

UGCX does not have this limit, as your speech recognizer can also be set to German, French, Spanish, English UK, or English AU.

Be mindful of that difference.


Problem: The tow bar is not connecting to the nose wheel.

Solution: Use the "Aircraft Offset" utility to define offset points for your aircraft.  It's available on the Options Menu.


Problem: The when the tug starts to push the plane back, the plane flips over.

Solution: Your parking brakes and chocks must be off.  If using the PMDG's or FSLabs Airbus, watch out for those chocks!


Problem: I'm getting pushed on to the grass.

Solution: In some cases, creating a "custom route" may be required depending on airport layout, etc.


Problem: I've selected German for the display language.  But these German characters: Ä Ö Ü ä ö ü ß" do not display.  They appear as Ae, Oe, Ue, oe, ue, ss.

Solution: We had to write it this way due to a unicode issue.  Every German will be familiar with this issue.  We have a possible solution coming up though.


Problem: I'm using Voice Control.  My voice command didn't register when I ask to start the push.

Solution: Depending on where you're going, some pushbacks may require you to speak facing/tail using a direction like this: "North west", "South East", "South West", etc., and that may catch you off guard because you're probably just thinking "North", "West", "East" and "South".

Look on the Airport diagram.  It'll tell you if you'll be using facing/tail "North West", etc.


Problem: I'm at a German, French or Spanish Airport.  My language in UGCX is set to German, French or Spanish.  But the ramp agent speaks English, not my own language.

Solution: In the Aircraft Profile menu, ensure "ENABLE REGIONAL SOUND SET" is UNCHECKED.

You will then hear native German, French or Spanish as appropriate.


When you're flying outside your home country, you'd then check ENABLE REGIONAL SOUND set to hear English spoken with the correct native accent again (Example:  British accent in the UK).


Problem: I'm getting stuttering audio.  

Solution:  It appears a recent Windows update may have messed with a lot of users sound devices.  Switch your audio device sampling rate to 16 bit, 44100 hz.  


Problem: Sometimes I see puffs of dirt when the ramp agents are walking.

Solution:  It's a scenery issue.  Some 3rd party scenery developers for some reason leave holes in the ramp instead of filling the whole thing up.  We're working on a fix.


Problem: Sometimes the UGCX vehicles disappear.

Solution:  From a user:

"I use WAMA. WAMA has an option to reserve the gate for departure and arrival and keep it clear of AI traffic. It does so by placing an invisible object at the parking spot so that AI traffic thinks that the gate is occupied and keeps it free. So during pushback I think as soon as I leave the parking spot WAMA places the object there. That apparently leads not only to AI aircraft getting deleted (sometimes UTL spawns an AI aircraft right into the parking spot I am pushed away from and WAMA deletes it within a second) but also to the UGCX objects getting deleted at that moment because of the invisible object placed there.

I repeated that several times and could reproduce it everytime. When I reserve the parking spot with WAMA the UGCX vehicles disappear during pushback. When I do not reserve that parking spot, UGCX vehicles stay there."

Also see a few sections down regarding an FSUIPC fix for the vanishing tug.

Update: Another user had this issue and said it was due to using FSREALTIME.  If using FSRealTime, sync the time then shut-down FSREALTIME.


Problem: No vehicles or ramp agents appear in FSX.

Solution: The path to your Simobjects UGCX folder is missing in your FSX.cfg file.  This happened with one user who had a mix mash of Boxed FSX and Steam FSX installed at the same time.  It was a messy setup resulting in issues with the SimObjects UGCX path in his FSX.cfg file.  If that happens to you, send us a support ticket.

Also see a few sections down regarding an FSUIPC fix for the vanishing tug.


Problem: I get a CTD just before pushback starts.

Solution: If your airport has no taxiways (some don't, like the default Andrews Airforce Base), it will trip up UGCX.  We're working on this one.  It's a rare situation.


Problem: The tug and tow bar disappear, then the ramp agents freeze up.

Solution: If you're using FSUIPC, add the line below to the [GENERAL] section of your FSUIPC.ini located in your MODULES FOLDER.  It should preferably sit underneath the other "zap" lines.




ZapCylinderAltDiff=0       <------ THIS IS THE NEW LINE


If this still doesn't work, backup your FSUIPC.ini file, then delete it, then run Flight Simulator and a fresh new FSUIPC.ini will be built.


Problem: I can't move the Bypass Pin Agent's Slider.  They're stuck.

Solution: Read the manual 🙂  You can't be in a parking spot!  Do it on the runway.


Problem: The PMDG NGX-U / 777 / 747 pushback is jerky.

Solution: Ensure you're using V1.7 or above.  In your UGCX aircraft profile, ensure "USE BRAKES" is checked.

Also, on  page 10/10 of the PMDG Simulation Options in the PMDG 737's FMC, ensure your option is set to RUDDER, not TILLER.

As of Version V2.0 or above, you can also try the FREEZE METHOD for pushing back.  That option is in the "Aircraft Profile" screen.

From a user who solved it:

"I re-calibrated all the flight controls axis including the steering axis. I also kept P3D tiller option off. I had this option on for the PMDG 777 and the stuttering came back, but with it off no stuttering. Thank you for your assistance. Wonderful program, I love it."


Problem: UGCX thinks I'm at a Heliport

Solution: Ensure you're using V2.0 or above.  V2.0 allows you to excluding any areas that may cause issues.

Problem: I'm using FSCaptain and things aren't going right.  I'm getting freezes during pushback.

Solution: In FSCaptain, set DISABLE_PROTECT=0 to 1
