I find the D-Jet project to be very interesting and believe it represents the real revolution in personal jets. While the proposed very light jets are actually miniature business jets, the D-Jet is a whole new concept because of its single engine and restricted operating envelope. I expect the D-Jet to launch an entirely new market for single-engine jets, as the introduction of the TBM 700 did for turboprop singles when it appeared in 1991. I think the keys to success for the D-Jet are its single engine, which simplifies transition for less experienced pilots, and its 25,000-foot ceiling. Insurance underwriters will be much more comfortable with owner pilots flying a single at 25,000 feet and below, just as they have been with the single-engine turboprops, and that makes the D-Jet available to more pilots. Also, the single engine minimizes cost of acquisition and operation. But, just as I was pointing out above, the gap between jets and pistons is still wide and Diamond announced a price of $1.398 million for the D-Jet. That's less than the cost of any existing pressurized single-engine turboprop, but is still hundreds of thousands more than the Piper Mirage, the only pressurized piston single.
