Those "elder" of us who learnt on the clocks and dials, a DC-3 and onto the F-28 for me, can appreciate and I believe intelligently use the glass concept as we always have the real underlying picture available.
Those who ONLY have glass, ONLY HAVE GLASS, and certainly it will happen, it all goes blank, and most of the time so does the brain for those critical seconds.
There is so much info on the one display, all very nice but not readily available in other formats in front of the pilot in a critical flight phase.
One of my fellow Instructors had to do an ILS/DME at Singapore for real on the stand-by A/H his side, basic ILS on the other side, lower screen, behind the other column, hand flown, as it was the only one of 4 screens still working in a L-31.
As the other pilot was a 200hr, first flight in the right seat, his options were limited to say the least.
BUT had a similar basic grounding in all the points mentioned above.
Be safe.
