I'm not sure what do you mean with "matches AES". The AFCAD that was posted here, was made by Harpsi, a forum user, but the only difference comparing to the one supplied with the scenery, were some changes in the airline assignements, but the parking positions and jetways, which are the main things that could affect AES, didn't changed.
Just be sure you are using the current version of Zurich, because the later versions come with an improved AFCAD that merges many of the modification Harpsi added so, the file that was posted on the forum back then, is not really necessary now.
You might ask AES author, Oliver Pabst on the Aerosoft forum, which version of the Zurich AFCAD he based AES on, and if there are any issues with the one we supply now, which is dated May 2009, just FYI...
