There is a separate metal panel at the bottom of the area there to the left of the MCP which goes up at the angle. It is held in by screws. Yes, there is a gap. How ever so slightly exaggerated it may or may not be in real life I don't know, but it's there. Rather than having 3D vertices clashing/thrashing and flashing like crazy in your eyes, I would say a happy medium was found here. It can be a draw order issue.
Enjoy the plane and all of it's awesome systems simulations instead.
