Thanks for the information. That should help. Dave

Update: This seems to be happening to users who us FSLTL for traffic generation. So, probably a problem with how they are generating their traffic. It would be good to know the specifics of what is used to determine ground vs airborne traffic. Thanks, Dave

I use FSUIPC Client to read AI Traffic and it works flawlessly in P3D, and FSX. However, it has issues in MSFS. Distinction between airborne and ground traffic seems to be a problem. Is there something different about the data in MSFS? In X-Plane, for example, I have to determine airborne vs ground traffic on my own using elevations. Do I need to do something simliar with MSFS? Thanks, Dave

Paul, Thanks for your help on this. I think the issue is that I was iterating through the TrafficServices.AirbourneTraffic collection directly and if that took longer than my One Second timer, I was getting the error. I have changed the code to create a new collection and copy the traffic to that before iterating. This seems to have stopped the errors. Thanks again, Dave

Paul, I'm still getting the error. I sent a PM with the code and some more detailed explanation. Thanks, Dave

Hi Paul, Thanks for the response. I'll look for thread issues and let you know if that fixes it. That could be it. Dave

Hi Paul. I'm getting an error when calling the FSUIPC.AITrafficServices.RefreshAITrafficInformation. I've tried limiting it to just Ground or Airborne traffic and still get this error: Index was outside the bounds of the array. at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at System.Collections.Generic.Dictionary`2.Add(TKey key, TValue value) at FSUIPC.FSUIPCConnection.AddOffset(Offset Offset) at FSUIPC.Offset.initDataInfo(String DataGroupName, Int32 Address, Int32 length, Boolean WriteOnly) at FSUIPC.Offset`1..ctor(String DataGroupName, Int32 Address, Int32 ArrayOrStringLength, Boolean WriteOnly) at FSUIPC.Offset`1..ctor(String DataGroupName, Int32 Address, Int32 ArrayOrStringLength) at FSUIPC.AITrafficServices.RefreshAITrafficInformation(Boolean UpdateGroundTraffic, Boolean UpdateAirbourneTraffic) at FSUIPC.AITrafficServices.RefreshAITrafficInformation() at P2ASim.P2ASimulatorFSUIPC.OnSecondTimerFired() I believe there are about 28 AI aircraft airborne when this happened. Thanks for your help, Dave

Paul, Thank you very much. I will give it a try and let you know. Dave

Paul, I've been using your Beta of the V3 dll for several months and it performs flawlessly! I saw on another post that you recompiled the v2.4 to x64, but it seems that the V3 was last compiled before that post and appears to be x86. Any chance of putting a 64 bit version out. Thanks, Dave
