I recently flew an older Cessna, in which the NAV frequency select was

Why do we see them so rarely?


NARCO. One of the few good things they ever did.


Yes & No! An excellent idea and saves panel space. We have one of
these but also have a selector switch so the DME readout (on the VOR 1
Indicator) can be selected to either NAV 1 or NAV 2.
Great when the VOR you're following does not have an associated DME or
you are using a VOR too far away to read DME but a nearby LOC/DME can
be used. Yes it's easy to make a mistake :-(

It ought to be possible now to do that quite practically with the
miniturization of components.
