Firstly. There was an AFCAD included in the first release. I can remember that. hapsi just updated the file to include some more precise infos aout where the different airlines and planes are parked.
Yes, indeed all sceneries come with a base file, let´s say. I just add some more things and correct a few ones if they exist. I don´t do afcads from the beginning and I am not taking part of the team as well. I am just a beta tester when I am requested, and I just do all the other work on the afcad files for pleasure, in this basis: if I have to do it for me, why not to share my work with all the others? that´s just what I do.
For this afcad, I already added a lot of few things, but if you ask me if the file is complete, I will answer: no, it is not complete because I am taking little informations from here and there. I don´t live in Switzerland so, I don´t know what is happening there in real life. I need users help as well, but be aware: it is just a free work to make more users happy and nothing more than that.
