In that case, you should add L/F four-course range simulation to your
ground
trainer. Who knows, they might come back?

As you correctly note, four-course ranges no longer exist, so there is no
purpose in learning or practicing their use.

Actually, I do not have a KNS-80 or other VOR/DME RNAV system in my
simulator; the KNS-80 is in my airplane. I agree with you there is no point
in a brand-new KNS-80 installation either in an airplane or in a simulator.
I am, however, debating in my mind whether to install a Garmin 430 vs. 530
later this year as part of an avionics upgrade, and I am leaning toward the
430 because it would save enough space to allow me to keep the KNS-80 and
thus maintain true DME and VOR/DME RNAV capability, two forms of navigation
which the Garmin 430/530 can only emulate based on GPS calculations.


Seriously, from what I see, most pilots are not spending enough time with
GPS
to master its use for IFR. Between that, ILS, and conventional VOR/DME,
the
plate is already full without trying to master computed radials.

I am not saying someone should install a KNS-80 today as part of an avionics
upgrade. But it does not necessarily make sense either to remove it just
because a GPS is going in. You are correct that many pilots have not
mastered all features of their GPS; what is wrong with an instrument pilot
attaining proficiency in all installed avionics, including both GPS and
viable/workable alternatives like the KNS-80?
