I for one am not really impressed with glass cockpits.
I remember doing quite a bit with my old steam gauge DC9. I knew where I was, where I was going and what sort of terrain clearance I had (using a chart plus nav instruments)
While it was demanding of my poor brain, it kept me on my toes...not just sitting back watching things happen and go bad before my eyes.
I like the old T scan for basic flight instruments and thought I had gone to Heaven when I got a good RMI and HSI.
While I always wanted a moving map display superimposed on wx radar, I didn't need it to survive.
Steam gauges got expensive to fix...glass cockpit...one tube and you lose alot...I lost an Attitude Gyro once...covered it up with a piece of paper and hung in there...
