As far as I am concerned the Cirrus Jet doesn't even exist yet. When they have delivered and have it fully certified it to do what they say it will do I will believe it. Otherwise, I am just waiting for another failure.
I would not buy one. Too many MUCH cheaper and better alternatives and too many far superior aircraft for around the same price.
If I had that much money to spend on a jet I would buy an older, Citation II, V, Bravo, CJ, or Sierra Mod 500/550 taking into consideration the increase in fuel burn and MX costs compared to the Cirrus Jet.
The service ceiling is only FL250. Less than a lot of turboprops and puts you right in the middle of most of the weather you don't want to be in.
It is very slow
It has 1 engine
Has no range
I doubt it has much payload with full fuel when it finally delivers.
I think this will be a great marketing opportunity for Cirrus to sell them to current Cirrus owners.
I fear for the aircraft's safety record. Another attempt to put non-professional pilots in an aircraft that may be too much to handle for them. The Cirrus SR22 has a very high number of fatal accidents. Now increase speed to 300 knots from 180, and let's see what happens.
