The only answer I can give is, while in the virtual cockpit, you don't need Active camera to pan the view.

You can assign panning to any axis you want. For a while I wasn't using the throttle on my yoke so I assigned left/right panning (don't remember the actual function) to the throttle.  I just didn't like the forward/backward motion being translated to side/side.

Or are you talking about being in walking mode. I'm sure (through FSUIPC) there is a way to translate axis into keypresses)
