That EPIC system is a real marvel, actually a bit similar to some research cockpits that I have flown. It is not just avionics, that is pronbably one of the reasons why its procedures look so long, on paper. It can be circuit breakers, normal switches, systems controls, health, autopilot, and avionics.
I had a demo CD at one time that was simply so far reaching, it had features that Comanche had, a real statement for a civil system developed with commercial dollars!
