Hi Nigd,
Have done a bit with glass cockpits but on helicopters. S'pose my main thought would don't be in such a hurry to lose the dials and knobs.
Dials can be much easier to interpret and assimilate at a glance. Engineers seem to love digitising stuff down to numbers and coloured strips.
Knobs, everyone likes to have multifunction soft keys to select crs pointers, baro setting, low height audios etc, sometimes life would be much easier with a good old knob rather than a few minutes stabbing away at bezel keys.
That iss it really without being too specific love those dials (or graphical equivalent) and knobs!
All the best
Ian
