Based on Cirrus' current numbers, they'll get their wish. With full fuel at a best economy power setting, which delivers around 210 knots, the jet will travel better than 1,250 nm (IFR range). Of course, few pilots will fly that slowly, so a more useful profile is the best cruise speed of 300 knots, at which the jet will be able to travel more than 1,000 nm, which has been Cirrus' high-speed cruise goal for the jet from the start. It goes without saying that loads larger than 400 pounds are going to decrease allowable fuel and, thus, range. Top level speed so far has been close to 320 knots, Klapmeier said, though he added that just 300 knots remains the goal.
