So sad, the Queen of the Skies is grounded in X-Plane due to a nasty bug 
I bought X-Plane to simulate long haul flights on a Mac computer instead of having to use an alternative PC based flight simulator.
However, it is impossible to do any long haul flights with X-Plane, until this critical 747 NAVRAD bug is fixed, as it is impossible to do any ILS approaches and landings on the only long haul plane that is provided by X-Plane.
I hope this much needed fix is a priority, in order to make the X-Plane 747 fit for purpose.
