Can someone point me to a VA that:

I must warn you that the high-realism VA's that would appeal to you mostly either strongly encourage or require VATSIM flying, so that does limit your options. I also don't know of any airlines that require the use of random system failures, but that's something you can always do on your own. If you were willing to join VATSIM, I'd recommend you look at CalJet VA (http://www.flycaljet.com). We haven't started flying yet, but it offers probably the most realistic atmosphere available in any VA today. Also, one called VOZ Virtual operates in Australia/New Zealand(http://www.vozvirtual.org). I don't believe they require VATSIM or FSMeteo/ActiveSky, but I've heard good things about them...Good luck!-Marc
