I think it's certainly reasonable that the greater one's exposure to various mediums and the more experience one has in a given environment, generally speaking the better an opportunity one has to enhance one's situational awareness.
Multi-function displays and combination instruments frequently seen in glass displays these days do certainlly tend to enhance situational awareness to some degree, yet manage to inhibit it in others if the user moves mindlessly forward with no effort beyond following the magenta line.
Several years ago an operator for whom I flew had a first officer who fit this mold...he was absolutely unwilling to put out any effort to expand his understanding. When tasked with something simple, such as falling back to laying in a manual course instead of selecting something from the FMS, he had no way to set up an airway, a radial, or fly a hold. One day he was enroute, somewhere in the middle of the country, and his captain pointed outside and asked this individual to tell him what airport he saw. The kid looked at his display, then at the airport, and said "it's in about the right position to be this one, but that can't be it."
The captain queried, "why can't that be it?"
"Because look at the runways. They don't go the same way as the ones in the display."
The captain noted, "Do you realize that the same symbol is used for all airplanes in the display...and that if an airport on the ground looks the same, it would be strictly a coincidence?"
This individual did not understand. Given his difficulty in followin the basic automation, and his inability to perform simple tasks when his attention was divided, I can scarcely imagine his incompetence with a basic six pack in a Seneca or a Baron.
One can never stray far from the basics, no matter what information is provided. Get get outside the loop and rely too much on automation or technology is to invite trouble when a lapse in either occurs...and it does, and will.
