I learned to fly instruments using steam gages. We put a KLN89B in our
piper and left the steam gauges in place. Transition to the KLN89B
didn't take long, it was done during an IPC (took all of 2 hours).

The point to this is, what little moving map the KLN89B had, it added
to situational awareness. It did not take away from the ability to fly
an ILS (which can't be done at this point w/ the KLN89B). However, I'm
more inclined to fly the map and GPS CDI (it has its own as opposed to
sharing one with a NAV) because of how accurate they are compared to
VOR.

This actually causes me to "forget" to keep up with where I am on the
IFR chart(s) should the GPS go south! (I tend to fly direct because of
it and would have to start tuning up the VORs etc. etc. and get a
vector or two).

And for an approach: I'd rather fly the GPS approaches any day compared
to a VOR/DME or NDB/DME (particularly because the ADF got taken out of
our plane). Think about it, how much wind correction and needle drift
do I have to deal with for NDB compared to GPS?

So my thinking is, it is easier for us old timers to move to glass than
it is for glass only guys to step back to the older technology. And it
is easier for me to transition back to all steam gauges w/ ADF because
I had to use them for my check ride and [self required] annual IPC
(self required because I stay current, but use the IPC in an attempt to
make me shed bad habbits).
