What exactly does Acceleration do?  Looks like a few planes, more missions.... which bore me.  Why in the world would CS design a plane that requires this add-on?

Davecat,  I only purchased Acceleration to make the CS 727 AP pitch control work correctly.  It did cause my other favorite plane to break, though, but I'm working on a solution for that.

Other than that, it does come with two new military aircraft and a new chopper.  Updated scenery, missions, and better Direct X 10 support are part of the update.  Not sure what else.  I imagine that eventually I'll play with the F/A-18 and the carrier ops that you can apparently get into with it.
