VJL Update

Hmmm....It looks like Cirrus is developing a dingle engine business jet, the SJ50, that looks an awful lot like the Eclipse 400 (previous posts here) that I discussed a couple of months ago.

It's pretty clearly a form following function thing, rather than any outright copying. There are relatively few configuration options for a single engine very light jet that the marketplace will accept.

Interestingly enough, it appears that Cirrus will sell it with a recovery chute, as it does on its piston engine models, which will be a challenge, given the higher speeds and energy involved.



First, Diamond International expects to certify its D-Jet and start deliveries some time in Q2 2009.

Seeing as how their engine supplier is not Thielert or some other new entrant, it's a Williams FJ-33-4A-19 turbofan, I would expect them to be on schedule.

Honestly, I think that the single engine VLJ is likely to be a winner in the VLJ sweepstakes, because the operating costs will be lower.


In the two jet VLG category, the Adam A700 has been rescued from bankruptcy, albeit absent the "Adam" name, as AAI, who purchased the company out of receivership, thinks that there is some bad market mojo there.

It appears to be among the most spacious of the VLJs, which may, or may not, be a function of its twin boom design.


Finally, Piper has flown it's VLJ Piperjet, which is another of the single engine VLJs, though it's somewhat larger then the D-Jet, the Eclipse 400, and Cirrus Jet.

It appears larger than its single engine competitors, but it just doesn't look right. Something just looks wrong about the aircraft, but then again, so did the F-4 Phantom.
