While complex to learn, having huge glass navigation systems sitting in front of you in a single engine plane seems so foreign to me.
I did my instrument ride in a C-172 and my commercial in a PA-44.
During both of those checkrides, I ended up having to shoot ILS approaches to minimums, in turbulent IFR conditions, with nothing but "steam gauges". The fanciest thing in the plane was probably the HSI.
On the instrument ride, I had to shoot an NDB approach to minimums in actual. That was a good time.
I assume planes don't even come with NDBs anymore. I used to tune into AM radio on them just to have something to listen to to pass the time.
I used the latest Microsoft Flight Simulator recently and loaded up the C-172. It just stared at the screen for a minute, realizing I don't know how to use a G1000 so I couldn't fly it. I mean, I could start it up and get it off the ground, but for IFR navigation? No clue. Lots of buttons and fancy graphics.
The march of progress.
