  1. Hello all, Apologies to all for re-igniting this thread. As those of you who followed my last thread know, I have been having extreme problems for the last three months trying to install and use this Flight1 GTN750 Complete product. I eventually gave up on the !@@#$&*^$%@#$#^ thing and uninstalled it after also uninstalling the Purchase Agent. The uninstall left a folder in Program data (Flight1 GTN750) I deleted I then checked User/appdata/roaming/Flight1 Aviation Technologies/GTN Gauge folder. this contained F1initcode that.gd188_gtsb_0_data gsm.pmf All of these files and folders were deleted and I followed up with a search on Dri…

    I am sorry if this isn't in the right spot, I wasn't sure where else to post but I need a little help. For the past week or so I have noticed that any add on from Latinvfr, Flightbeam and DD have black scenery. Now I can temporarily fix this issue by reinstalling said scenery and it will work. It will only work for one scenario of P3D then on the next load up go back to being black. The area's that are back is the taxi ways, terminal buildings and apron. The land class remains unaffected. I am using ORBX base pack, NA land class and HD tree's. I feel like an insertion point is wrong or something is causing the add ons to go black once I exit P3D. Like I said I can te…

  4. I've recently been thinking about purchasing the Flight1 G500/G600 but on Flight1's page it states that it requires the GNS or GTN from Flight1. My question is, is does the F1 G500/G600 work with the RealityXP GTN series? I bought the RXP GTN over the Flight1 GTN because I've heard that F1's framerates aren't as good as RXP and also F1 uses an older Garmin Trainer. To anybody who has the RXP GTN / GNS and the G500/G600, does the F1 G500/G600 wok with RXP GTNs?

    Ok I know that Taxi2Gates KMCO isn't officially compatible with V4. However, after seeing a few posts here and there and some others saying it works fine I decided to purchase the scenery for P34. My only issue is that the taxisigns are in the middle of the taxiways and there are two windsocks. I removed the FTX KMCO files that sorted out the duplicate control tower issue, but the taxisigns and others are still there. Is there any fix for this?

    Hi All. Recently changed to DD for JFK. I also downloaded the inibuilds JFK gsx profile. I'm happy that I now have a more current and correct JFK, but confused with the whole gate thing. For instance. The GSX menu would list gate H40. But the real gate (which is correct in the DD scenery) is T8 Gate 36. Did I do something wrong? The other gates are like this as well. thanks for the help

  10. Hi, I'm suddenly finding that Active Sky is no longer injecting weather into P3D 4.5 . All I changed was that I purchased and installed the Aerosoft A330. I uninstalled and reinstalled Active Sky build 7208. Then I tried build 7361. I reinstalled Simconnect several times. I even tried repairing P3D V4.5 Client. I submitted a ticket to HiFi Sim but don't yet have a response - not sure their support is very active? Active Sky says it's connected, but the weather never gets injected. Does anyone have any ideas what might have gone wrong? Thanks, Daniel

  11. I tried installing the milviz 737-200 into my P3dV4 and it crashed to the desktop near the end of the process. Installed with no problem into FSX-SE. Now whenever I load anything else the screen keeps twitching about every two seconds. Am I going to have to do a fresh install (and have to reinstall all my 3rd party aircraft)? Doesn't happen with any other simulator (FSX, XP11, TS2020). Ken

    I have this matter... Sometimes AI engine injects double flights at airports. Or aircraft, it's not flight cause one aircraft starts moving the other stays on the ground. Please read below. As an example, here is Madrid. You can see TWO Ukraine International 737-800 on the ramp: The AI engine shows they have different tail numbers: UIA flies to Madrid only 5 times a week. So there is not even a single possibility of a double daily flight. Morever this is confirmed by AITM: We can see only one daily flight. What can be the reason of this phenomena? To clarify, I am a pro with AI, so there is no possibility of a double bgl, or someth…

    Hey! When I was flying to Paris Charles de gaulle, I noticed that the entire airport has been moved up from the ground level a bit. I notice this at airports around Paris. I have looked away in Dusseldorf too but noticed nothing strange there. I have no airport scenery installed or anything. All I have is Orbx global and europe. But if it had had to do with it, would it have been so all over Europe? Does anyone know how I can solve this? Sincerely Axel

  20. And so I went from 30fps to 9fps overnight and lower when in the FSLABS A319. Removed everything, run CC Cleaner on the registry and reinstalled exactly as was previously. Now sitting steady 40fps around London in the FSLabs. One think I didn't put back on was Ultimate Traffic Live as I found this to loose me circa 15fps. Any recommendations to a replacement product for traffic as I tend to fly offline from time to time as well and it can get a bit lonely up there. Thanks

  23. Recently I started finding that when I tried to start REF it didn't load the programme. The I discovered that even when it is not running I have this entry in my TaskMan for REX Environment Force. If I kill that entry in TaskMan, then REF will load properly next time. But when my session is done and I close REF, I am again left with the REF entry still in TaskMan although there is no sign of REF actually running. So next time I try to start it, it fails again and have to kill it in TaskMan yet again before it will load properly. Anyone else seen this? The fault has survived the latest update to REF 2.2.1 today. I tried to contact REX sup…

  24. Hello there, I've developed a RAAS system in Lua which is NOT aircraft specific. Then alert as "Runway too short" for exemple are not implemented. It seems that such system is not something that many simmers are looking for (or maybe many already own a payware RAAS?). But anyway if some of you are interested to test it, just tell me and I'll give you a download link in PM. Here are the pre-requisites: Registered version of FSUIPC "R4.csv" build with "MakeRunways.exe" utility from Pete Dowson A least 1 english SAPI voice installed in your Windows I think it should work also in FSX and P3D x86 versions, but not tested.

That's all there, I haven't changed anything. I even deleted the VehicleFavorites.xml file and let it rebuild. Thanks for any help, Daniel
