Good Afternoon everyone,Just like the topc title says i'm considering flying on VATSIM. I'm new into the forum so i hope this is the right location for my (newbie) questions. I did some research but I can't find all the answers. Let's kick off (or should I say take off :( )Are 3rd party scenery add-ons allowed on Vatsim like FlyTampa's Orlando (KMCO) for example? The reason for asking; what will happen if Simmer A owns the add-on and Simmer B not. While ''Simmer A'' thinks he is parked gently at the gate it can look like he is blocking the taxiway due to differences in the scenery.How does the ''AI'' work? I understand their is no AI like flying offline but how can I see other traffic when I'm not in prossesion of that model. For example; I'm taxiing on a busy airport meanwhile someone else taxiing with a Level-D 767 which I don't own. How am I enable to see the traffic? The same question rises to me with liveries I don't have installed. Will I just see a grey aircraft?Can I see people who are using FSX on VATSIM while I'm online with FS9 and vice versa?I looking forward to read the (hopefully) responses.CaptainSlow

Yes, and they're widely used. They cause some occasional conflicts, like at some airports (PANC for example) where an add-on or approach plate may be more current and reflect a new runway or renumbered runways. At PANC, if somebody asks me for the old (FSX stock) ILS 06R, I'll give it to them, knowing that it's now 07R. Most online controllers I know use current approach plates, and adapt for users of the older stuff. The conflicts with position on the ramp etc are generally easily resolved.

The VATSIM software taps into the FS multiplayer capability already built into the sim. If you don't have a matching livery, you most likely will get the closest generic match for that acft type.

Can I see people who are using FSX on VATSIM while I'm online with FS9 and vice versa?

Yes, you can.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

Thank you very much for you clear answers. CaptainSlow
