The sentiment of the question makes sense, but the details do not.

The job that needs doing doesn't depend on MP versus pilot.  It depends on
point-of-view (PoV) and field-of-view (FoV).  
 -- In some high-wing aircraft, the gear can be seen from the cockpit,
  even in non-MP simulations.
 -- Cockpit view is only one of several viewing modes.  The outside of the 
  aircraft is visible from many of the modes, even in non-MP simulations.

 *) The job needs to be done by the graphics subsystem, not by the author

  it is not possible to account for them in the model file.  The model file
  should specify the 3D positional relationships of the parts, and the
  graphics system needs to figure out which parts need to be rendered and
  which don't.

In an M-player simulation, there will be M different views of the same 
situation,
but that doesn't change the nature of the job.  It just means there are M
copies of the same basic job.
