Well, I'm sitting here browsing through Diamond's webpage (http://www.diamondair.com) and I started looking at the specs on the DA-42 TwinStar. Reading through these specs I was quite suprised, it doesn't seem possible. Especially 180ktas buring 9gph total and the useful load.
The performance of the 270 hp TwinStar sets new standards in this class. Projected performance offers over 1400 mile range, 180 ktas cruise at 9 gph total, 203 ktas at 12 gph total at 12,000 ft, useful load of over 900 lbs plus full fuel, and a sea level climb rate of over 1700 fpm. Single engine performance will redefine the safety margins in this class. With a projected base IFR price under US$360,000, and low operating costs, the TwinStar offers a realistic and safer alternative to high performance singles.
Optional equipment will include a glass cockpit, oxygen system and anti/de-icing.
Unless I'm seriously misunderstanding some fundamental twin/GA knowledge, is this thing going to be a revolution in light GA twins or are we experiencing a company being very enthusiastic and exaggerating about its airplane's capability? Whats the secret to this thing?
