Paul,

After flying and instructing in both types of cockpits, my experience
is that the "glass' version is far easier to use, cuts workload
dramatically and, in my opinion, makes instrument flying much easier.
It allows information to be obtained and processed faster and helps
one's situational awareness significantly, allowing the pilot to stay
well ahead of the airplane, even as the workload goes up in a terminal
area. All of that recognizes that there is a learning curve to the
glass cockpit, but the presentation is so intuitive, that one catches
on quickly.

All the best,
Rick
