You're right, it doesn't matter on VATSIM. I often take my B722 or B732 to extremely noise sensitive airports on IVAO or PilotEdge and nobody has ever risen an eyebrow. Last year I've even met a guy overflying continental Europe in a Concorde . It's just a computer game anyway - therefore the number one requirement is to have fun . For the default X-Plane FMC, I believe that the answer is unfortunately 'no'. It's very limited in functionality. The SID/STAR procedures are implemented neither in the X-Plane default GPS (not even the new one which came in the 10.30 version) nor the Carenado G1000. You have to use either some kind of "aftermarket" universal FMC* or buy an aircraft which come with one. Flight Factor made aircraft with very complete FMC, though they are not perfect. My personal favourite is their B757 - panel is a mixture of modern stuff and clock-work style of 1980s and FMC is from pre-GPS era so it can lose precision if you fly a long time without signal from DMEs (but within range it will calibrate its position automatically and AFAIK it's legal to fly real-world RNAV with equipment like this). B777 is more modern aircraft with modern systems, however it's Flight Factor's older model and it's noticeable. Just beware that their latest work, Airbus 350, doesn't support SIDs/STARs. Another very popular option is JAR A320, however the FMC is lacking well behind Flight Factor. But it's perfectly usable and if you prefer Airbus over Boeing, it's a way to go. You can also check JRollon's CRJ-200 (here on X-Aviation.com is sold as Take Command! CRJ-200). An older model which looks rather simplistic compared to above mentioned aircraft, but with hands-down the best manual. It's probably the only aircraft manual which is fun to read . * Popular universal FMCs are X-FMC (freeware plugin, universal FMC with Boeing-style CDU), iFMS (again Boeing-style, but stand-alone for Android or iOS devices), AirFMC (standalone iOS; many people like it but I don't have any iOS device so I haven't used it) or UFMC (payware plugin, better than X-FMC in many aspects but quite intrusive). Another way of VATSIM flying is to file a flight plan with equipment code /A (or /W if you want to fly above FL290). Then you don't need any FMC and it's more fun [redneck smile] .
