All these discussions about panel upgrades and so on begs the question as to
which setup- a an EFIS and flat screen set up or standard spinning gyros
works better in terms of delivering an intact crew and passenger to the
terminal and a plane that is reusable for further flight. I clearly agree
the panels look cool, but I do pay attention to peer reviewed science.  The Cirrus folks did a study and the results published about a year ago
comparing the conventional gyro panels and the EFIS in the same model of
plane- as close a randomized controlled trial in aviation as possible these
days.  The EFIS cohort bent more planes and orphaned more kids than the old school
gyros. So I won't be flying with an EFIS until someone can prove they're safer.
