In a real airplane you don't have screen borders, a nose you can turn off,

I know (although actually you can put something on the windshield that can
work in a similar way).

The point is the validity of finding the spot that doesn't move, not the
reference that you use to do it. Hopefully you wouldn't be lost in the sim if
you had no aircraft nose to use as a reference.
