I transitioned to glass when I went from the B747-300 to the -400. Glass is easier by a long way and I never had too many issues once I worked out where everything I needed to see was located on the screen. One of the great things about glass is that you can choose what you see, in the old -300 you could see everything all of the time, about 900 dials and switches to monitor.
On the -400 you could choose to see only what you needed to see right now. Much easier to monitor and more relaxing to fly. If something came up that required your attention, the aircraft would tell you about it automatically, and tell you what to do.
I even upgraded the ''six pack'' in my own Cherokee Arrow to a Garmin Glass Cockpit. The amount of information I can get out of it is far beyond anything I could have dreamed of when I started flying 50 years ago. For me, old fart that I am, it's glass all the way.
But I can still fly with 1930s instrumentation any time I need to.
For some it is, or was difficult, and for others, not so much. I have a friend who began flying prop-driven airliners in the early 1960's. He took an early retirement from being captain on the L-1011 fifteen years ago because he the found the upgrade to a glass cockpit 747-400 too much to learn and he didn't have a background with personal computers.
I was flying "steam gauges" for over 20 years until I transitioned to glass and found it quite easy, partly because I've been using PC's since they were first invented.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
