A case can be made that the twin-diesel DA62 from Austria’s Diamond Aircraft represents a new pinnacle in piston aircraft design. Its long list of positive attributes includes superb efficiency, quality construction, technological sophistication and aesthetic appeal from every angle. With so much going for it, there’s little question this is an airplane that belongs on the shortlist of the greatest light twins ever. In a word, it’s a winner.

It’s a pity, however, that so few people are expected to buy it. Don’t blame Diamond for that. Light-piston twin sales have been so slow for so long that most aircraft buyers — and aviation writers — have written off the segment as all but dead. And no wonder. There aren’t nearly as many pilots hanging around airports today who will tell you they need a twin. That’s mainly a byproduct of the rise of high-performance piston singles like the Cirrus SR22 and Cessna TTx, which can do pretty much everything a twin can but with substantially reduced operating costs and essentially no safety penalty.
