When you re-start FSX, some things (view/camera-wise) come from the saved flight and some come from the default flight.
FSUIPC (even the unregistered version) saves the current flight as "Previous Flight.FLT". I make this my default flight also.
When I close my flight with an UNDOCKED GPS on screen 2, that is exactly where it is when I restart the flight. Whether it would also be there if I created a new flight, I don't know, but you can certainly experiment with this approach.
Obviously, different aircraft have some different views so this might not work for all reloads, but see if it helps...
