Alejandro - the virtual cockpit is a dynamic view in the sense that it simulates the motion as your head moves.  In it, you can also set the intstruments to be dynamic, in that they are not static bitmaps, but operating gauges, switches, etc.

You cannot add a virtual cockpit to an existing, compiled model.

If you are already familiar with 3DStudio Max, you should be able to get and use gmax with no problems.
