But the PiperJet would be in a different category of light jet. With its proposed top cruise speed of 360 knots it is as fast, or faster, than the light jet twins. The announced 1,300 nm IFR range is amazingly long, longer than other light jets and better than many, much larger, traditional jets. And its 35,000-foot ceiling is smack in the middle of the high jet flight levels, and not far from the 41,000-foot maximum of the multi-engine light jets. With its expected performance the PiperJet transcends the personal jets, but because it has only a single engine, it will be much more accessible to pilots without considerable multi-engine experience. Insurance companies have been quite comfortable with lower time pilots moving into the single-engine turboprops such as the Piper Meridian, TBM-700 and now 850, and the Pilatus PC-12. It seems likely that the attitudes will be similar for the PiperJet, particularly when you consider that the TBM-850 is already close in terms of cruise speed and altitude. In fact, much of the expected PiperJet performance can be credited to having only a single engine because that one and only engine requires a lot less fuel than two. That's good news at the fuel truck, but in terms of performance, it's all about weight. With one engine you save the weight and drag of a second engine, but more importantly, you don't need to carry the fuel to feed it. With less fuel the airplane weighs less and is thus more efficient, whether you take that efficiency in terms of speed, or slow down and reap the benefit in range.
