Since the commercial difficulties maintaining the development of the Aviation Technology Group Javelin military-style light jet, (http://www.avtechgroup.com/) I have been scouring the glossies for something that would replace it as my object of desire. Any suggestions ? Nominations on a postcard, or even posting here...

MMMmmmmmm, the Diamond D-Jet website (http://www.diamondair.com/aircraft/djet/index.html):
• Personal, single engine jet
• 1351nm range
• 315 ktas cruise speed
• Operate out of 2500' runways
• Garmin glass flight deck
Sounds great to me. Five passengers,Garmin glass cockpit and reasonable cruising speed. All this for under 1.5M USD. Nice. I have not seen one in the flesh.

Take a look at this, from Cirrus Design : The Jet (http://www.the-jet.com/infobase.html). Ultra modern looks with V tail, five seats. Not yet available though, so we can wait for the certification. Expected price about 1MUSD. Which is a bargain.

There's two things I wonder about that design (actually three come to think of it).
1) Engine placement - it's going to be a b*tch to service
2) Engine placement - will it not get turbulent airflow at high AoA's?
3) Engine placement - by the looks of it seems to generate quite some downward thrust (pure parlor talk derived from a picture). In the event of a go-around, what will be the effect of thrust increase on pitch?
All interesting points. My first concern was being a (paying!) passenger in the rear with an engine behind my head. I hope the noise damping will be good ! The new Honda Jet has two engines mounted well above the wing surfaces. Similar servicing issues I would think as its not a drop-out solution.....

That Cirrus is good looking but I too am concerned about the engine position.
I've been following Spectrum Aero for a while not least because a friend is involved in them http://www.spectrum.aero/
New technology, lighter airframes so smaller engines and fuel bills. They're a year or two from being available but I hear they just ordered their simulator which will enable them to do 40% (?) less test flying.
Yeah, Isnīt technology a wonderful thing ? Expanding the flight envelope using simulators is a great way to say money! The effects are felt throughout aircraft development, as use of standard components and interfaces in the embedded systems means that the development cycles are drastically reduced. For a fly by wire systems, especially FCS and safety critical functions the problems comes during certification.
Aircraft that look great on the drawing board from invariably run into cashflow problems, which will be exacerbated waiting for certification. I am not familiar with the aircraft you mention, it certainly looks the business, and I look forward to seeing it in production !

Adam Aircraft files for Chapter 7.
From PE Week Wire
Adam Aircraft, an Englewood, Colo.-based maker of twin-piston and jet airplanes out of carbon composite materials, has filed for Chapter 7 bankruptcy protection. The company is liquidating its assets to pay off creditors, including Morgan Stanley, which last year placed a $105 million senior secured credit facility for Adam. It had previously raised $182 million in venture capital funding, from Goldman Sachs, DCM, Mesirow Financial, W Capital Partners, D.E.Shaw Laminar Portfolios, Acadia Woods Partners and Hunt Growth Capital
