What makes it different
The DA40 is what a training aircraft looks like when the design starts from a clean sheet in the late 1990s rather than the mid 1950s. The airframe is composite rather than riveted aluminium, the wing is long and slender in the manner of a glider, and the tail is a T rather than a cruciform.
The NG model burns Jet A-1 through an Austro AE 300 diesel, which matters more than it sounds. Avgas is leaded, increasingly scarce outside North America and Europe, and expensive. A diesel that drinks 19.3 litres an hour and runs on the same fuel as an airliner removes a supply problem for flight schools operating far from an avgas pump.
Its long wing gives a flat glide, which changes engine-failure training from an exercise in rapid decision-making to something closer to soaring. Diamond's accident record in the type is the strongest argument for the design, though as with any aircraft the figures reflect how and where it is flown as much as the airframe itself.
