CJ2+...book sez sea level MTOW to FL450 in 28 minutes, assuming ISA.

Real-world operators have told me expect the CJ2+ to get up there in 25 minutes; during our demo flight with about a 10.5k MTOW it took about 23 minutes to get to 450 with a 2 minute level at FL410 for traffic, and after 5 minutes at altitude we had to pull it out of the cruise detent because the overspeed warning was going off. Not bad for a straight-winged Citation!

The Premier DOES have an extremely nice cabin and top-line avionics...I'm glad to see Hawker Beech is addressing the aircraft's other shortcomings to make it a true competitor in the segment.
