****The experience of the diesel, as I said, is different, but it's also an easy transition, especially since it's integrated so beautifully with the Garmin G1000 flat-panel avionics suite. (Duane Wallace, the visionary who dreamt up the present-day lineup of piston singles, surely never saw this coming.) The new engine sounds deeper, throatier, than the Lycomings, and the vibration is different, though not at all unpleasant. I'm sure that a lot of that has to do with the impressively smooth engine mounting system that Thielert has developed for the powerplant. There's no doubt that while it's different, the TD will be easy for new and old Skyhawk pilots to learn to fly. It's just not that complicated.
