I use ActiveCamera Pro, it is a great program. It lets you move around the virtual cockpit using the numberpad, you can also zoom in and out etc, so you can position yourself just where you want by the wing, and then save your favourite combinations.
However it payware, for the popular aircraft you can usually download some ready made wingviews from AVSIM and FlightSim.com.

Once you have tasted flight, you will walk the earth with your eyes turned forever skyward
