Problem started over last couple of weeks on SU11 and now SU12.
During taxi, the aircraft suddenly comes to an abrupt stop and will not move. However, the cockpit instruments still indicate a positive ground speed. I can turn the aircraft left or right with rudder pedals, but cannot move forwards or backwards (by applying reverse thrust). Positive GS, no actual movement.
Setup is:
PC (Steam)
PMDG 737-800
FS2Crew 737 SOP1
FSLTL + AIFlow + AIGround (My suspicion is the issue lies somewhere in these 3)
I’ve only noticed this happening at EGLL (iniScene).
I’d really appreciate any suggestions because it’s so frustrating… Takes best part of 30 mins to plough through start from cold and dark, so for it all to go wrong before the fun starts is getting me down.
Have you not tried turning these off to see for certain?
I’ve tried turning them off while it’s happening, but that doesn’t resolve the issue. I can try without running these from the outset, or perhaps just running FSLTL, to see if that makes a difference, but because it’s an intermittent problem, I’m never sure if it’s resolved or not.
All I can say is I use EGLL and FSLTL a lot and have never encountered this so perhaps try removing the other one, AIGround (which Iv e never actually heard of)
Do you use the PMDG 737 with iniScene’s EGLL, just so I can discount that as a cause?
Yes I do. The 800 is the one I use the most
This may be related to you issue, or not: I was having the same problem for a few days quite a while ago and discovered that my brakes were rubbing / slightly engaging even without my feet on the rudder pedals. I have MFG Crosswinds and checked my calibration and found that I had the wrong checkboxes checked for my brake axis’. Changed them and setup auto calibration and no more brake issues. Like I said this may not be your issue, but it may worthwhile to check this.
I’ve got the Thrustmaster TPR pedals. I guess it could be but the fact the aircraft is registering a positive GS suggests it’s more a bug in the sim of some sort, possibly brought about by the add-ons maybe.
It’s so wierd; I can apply the brakes while apparently frozen, which immediately causes the GS to go to zero. And then, come off the brakes, apply thrust, GS appears to increase but the plane doesn’t actually move through the scenery.
Do you have the rolling cache on? If so delete the contents.
Tried with an empty community folder?
I would run with just the 737 in the community folder, and not start any of the other programs you have mentioned.
See if the 737 works OK by itself.
Hi @TheSevenflyer , thanks for the suggestion. Yeh, rolling cache isn’t enabled for me; don’t benefit from it in my case.
I think you’re right, ultimately I’ll have to go down that route - i.e start from the most basic setup with empty community folder and no 3rd-party apps running, and slowly build back up from there.
I guess my hope was I could avoid the hassle of that by someone recognising the symptoms of my issue from their own experience and be able to point the finger at what the culprit was in their instance.
I mean, it could even be an issue with the Livery i’m using on the PMDG 737. Although it’s installed via their Manager, it isn’t one of their official liveries. I think I’ll also flip that over to one of the official liveries and see if that helps at all…

I’ve had issues with a couple of liveries I had installed as well.
If this is the cause, and you have a lot of addons, put them back in in groups, till you find the group that causes it, then narrow it down to the addon in that group.
Remember, it doesn’t have to be a mod associated with the 737, any mod can cause a conflict.
I’ve seen airports that caused aircraft issues.
