As I wrote above: The camera viewpoint is ALWAYS perpendicular to the center of the main (middle) screen. If you move the camera around in the virtual cockpit, it ALWAYS points to the center of your main screen. This is how the picture on the screen is built from the scenery around the camera viewpoint.
This is the same in all simulators, games, 3D visualisation apps.
You must move your yoke to the center of the main screen. If ther is not enough space, you would have to move farther away from the screen and adjust the zoom (FOV).
