The tutorial issue is covered in the FAQ for the 757 at least.  Basically, we give you manuals.  There is no tutorial.

Whenever I buy any payware airplane, the first thing I do is look for the tutorial.  Fortunately, the 757 is close enough to other Boeing addons it is very easy for many simmers.  The 727, on the other hand, is going to be quite a bit different.  I remember I did a radio navigation tutorial for the old 727, but I guess it is gone with the old forums.

Nailing intersections using only your radio navigation equipment is a lot of fun once you learn how to do it.  I have been spending too much time in the 757 to do more than take off, turn around and land in the 727.
