By “real world ATIS” I assume you mean the ATIS in xplane based off of real world weather updates? Xplane simply doesn’t know the real configurations of airports therefore if the wind is calm, it won’t know what the airport uses by default. The only true way to have your ATIS match up with the controllers and flows on PE is to use the ATIS on
www.myflightroute.com. One day...maybe one day...those ATIS broadcasts will be incorporated directly into the sim by PE. But for now, you can only get the ATIS externally from the sim on that webpage if you want accurate airport runway configs.
