From a U.S. Private Pilot: My buddy's youngest is a First Officer on the B737 with Alaska. His only comment was that an emergency "CESSNA" button on the instrument panel to kill all digital input except for primary controls, slats, flaps, brakes and steering would be nice; allowing for good old fashioned piloting skills and, hopefully, a safe manual (Cessna) landing.
Possibly an enormous over-simplification but is that possible?
