I recently watched a few videos of flights in the Cirrus Visionjet, literally the smallest and lowest cost single engine private jet aircraft on the market. Its electronic cockpit looks very straightforward and logical in design.
The Vision Jet uses the Garmin G3000 which is an upgraded version of the G1000 which is quickly becoming the standard avionics for general aviation (new) airplanes. Incidentally the Phenom 300 uses the G3000 as well.
If you can fly a G1000 in a Cirrus piston or Cessna, the G3000 is an easy transition.
The avionics and FMS of a typical airliner is positively COBOL by comparison. To get type rated in modern GA jets is pretty easy because the avionics are generally what you are already used to. However, the G1000/G3000 aren’t part 25 certified, however there is now a G5000 that is Part 25 legal, so I expect there to be some considerable improvements trickling up into the bigger jets. (Part 25 is basically “transport category” aircraft.)
Mechanically simpler or not, I finished a Garmin install last week on a piston-engine Lancair. I would absolutely call the avionics and engine indicating systems intuitive and easy to use, even without being a pilot.
While it's no G1000 or G3000, the G500 TXi, GTN 750 Xi, and GI 275 are all very straightforward, with engine indications being displayed on the G500 Xi in an easy to navigate package.
