Hello @ll,

the last few weeks I have been running many tests with LorbyLiveTraffic, trying to find the cause for the simulator crashing when using the "Simulator AI" mode (where the real world aircraft fly as simulator controlled AI, interacting with ATC etc.).

The bad news is, that there isn't a clear cause. The same aircraft being assigned the same flight plan will sometimes crash the sim, at other times it doesn't. It also depends on the active scenery, an AI plane might crash the sim when using the same airport from an addon developer as opposed to the default. My best guess is that it has something to do with the ATC mechanics in the sim, but I can't prove that.

The good news is, that there seem to be ways around that. I was using FLAI for all my tests, and at a certain point I noticed that there was always the same airplane model involved when the sim crashed - in this case the FLAi_FAIB_A320IAE* . So I replaced these FLAI Airbus models with those from MyTraffic - and haven't had a crash since.

What I did to replace the FLAI A320 IAE:

1. Copied the A320MX folder from MT6 to the FLAI airplane folder
2. Then used the Database Editor dialog of LLTX:
   • Sorted the "Aircraft models" list by clicking on the column header "Model"
   • Scrolled to the part where the models named "FLAi_FAIB_A320IAE..." are
   • Selected all of them and assigned the ICAO Airline "n/a" - that makes them irrelevant for LLTX
   • Then I used the "Add models to Database" section to navigate to my copied "A320MX" folder and "Scan folder" it (scan only that A320MX directory, not all of  FLAI !!)
   • This adds the MT6 A320 models to the main list above, while leaving their ICAO Airline column empty
   • Then I sorted by "ui_variation" and just scrolled through the list for those empty ICAO Airline cells, assigning the correct ICAO codes as I went

Make sure to always use the latest version of LorbyLiveTraffic. I am working on and with this app all the time, fixing bugs and adding new features.

Best regards

Im guessing its the last one... the saab 2000.

It could be any of those, the list shows the last attempts at creating aircraft. In my case it was the A320 IAE from FLAI. I used the information in the create log to disable the aircraft shown in the list until the crashes stopped. The quickest way to disable them is to rename their aircraft.cfg ot .off, or you could set their Aircraft ICAO code to "n/a" on the aircraft database dialog.

But the crashes stopped for good when I started using AIG OCI, those models seem very stable in P3D V4.

Thanks for the reply.  I'll do some investigating. Keep up the good work with your brilliant software 

Hi Oliver,

I have literally hundreds of hours using this excellent program and I have never had a CTD until recently. In fact I don’t think I have ever had a CTD on this PC with P3Dv4 (any version)...

Using P3Dv4 HF3 at Justsim ELLX I get a completely repeatable CTD within about 2 minutes of starting LLTX. If I don’t execute the program and fly with normal UTL AI, there is no issue.

I use AI mode, and route finder to generate the plan.

LLTX will crash the sim both at default ELLX and at Justsim ELLX. Regardless of aircraft. From the default F-22 to a PMDG aircraft.

This is for information only, as you say in your post above, there is not a clear cause. I just thought it worthwhile mentioning that I have happened to stumble on an airport where for whatever reason, LLTX and the airport don’t like each other 🤔

I just turn it on once I reach cruising altitude 👨‍✈️departing this particular airport.

Kind regards and stay safe,

Mark

Hi Oliver,

Lovely update to version 3. Just beautiful - Navigraph and all!

I have managed to find a way to avoid the issue in this topic by using GPS or great circle option rather than complex IFR or the 3rd party flight planner.

I will switch back to complex IFR and see if using Navigraph solves the issue.

Thanks again!

Hello Mark,

I also thought that it was about the flight plans. But it wasn't. I captured the assigned flight plans in debug, and when the sim crashed, I tried to recreate the flight with my AiTrackerX - and it worked almost every time (except for the models listed above, those always had a 50% chance of failure). But since I use AIG OCI planes, the crashes are all but gone.

Unfortunately, it is impossible to find out what went wrong from the outside. Or why the sim sometimes refuses to create perfectly valid AI planes, only to create them fine a few minutes later. Or why it decides to delete AI planes that have been created by a client program. I have tried literally for years now - but these are matters that only Lockheed programmers could pinpoint, for example by running the sim in debug mode and waiting for the crash/exception 22 - then determine the cause. Or give us an error log where details about exceptions are listed.

Btw. LLTX will capture native/BGL based traffic too, display the tugs and marshallers - and make it fly SIDs (provided you have a Navigraph subscription).

Best regards
