I have just installed x-plane 10 64bit yesterday and want to get involved in the community. I need to pick an aircraft that I can learn, preferably with auto-pilot, and using jets for long flights. I want to use xsqwackbox but it does not yet work with my version of x-plane. What is a good place to start as far as learning a new aircraft and joining a virtual airline/ online community to learn and contribute? What aircraft should I start with? I need to learn how to program in navigation from airport to airport and many basic things like that, I have the basics of flying down but struggle with some of the more complicated onboard computers in these aircraft. Any help would be appreciated, just point me in the right direction! -Whizzard
