Well without defining VLOS it means you can fly the plane to the next galaxy if you keep an unbroken visual line of sight. The AMA defined what they meant by VLOS but Congress did not. But then they said to follow CBO rules, but the FAA says that this means that a spotter can not be used for FPV. So if they are not using CBO rules you go by what Congress said and then you can fly as far as you want as long as that imaginary line is not broken.
