I have purposefully stayed out of cirrus threads because there is no arguing the chute with the cirrus zealots.
The jets a bad idea for multiple reason but that has nothing to do with cirrus.
I do not understand the intimidation factor? Steve, Your position, thoughts and comments about Cirrus are rather self evident; just on this post alone. Tim

An Eclipse will spend a good bit of time at altitudes well below FL410, where fuel burn will be above SF50 levels. Actually, I don't think that is true. I think two PW610Fs burn slightly less fuel than one FJ33-5A at comparable altitudes. Not saying Eclipse is better, but I am saying the reflexive assumption that one engine is less fuel than two doesn't hold for jets necessarily. This is piston think. Quote: Here the SF50 excels, with hourly costs expected to be 200-300$ less per hour than Eclipse. Remains to be seen. The odd part is that as fuel prices go down, the SINGLE jet wins more on balance due to burning more FUEL per mile. That is the opposite of pistons where higher fuel prices HURT the twin. The SF50 is perfect because only the marketing department of Cirrus gets to say anything about it. The Eclipse has a troubled and well known history. What will we think of the SF50 ten years from now? Mike C.
Mike,
You keep making this comment about piston think and single vs twin jet engines. By this point, you may have realized that Cirrus has redefined "piston" think about single engine airplanes. Further, with the high bypass ratios on modern jet engines they actually are becoming closer to resemble turbo props then older jet engines. Oh, this is not my comment, but one I read a while back from an engineer at GE discussing why the firm is going after the TP market with new engines. GE is applying knowledge gained in the jet engine market to the TP, that is why they are promising a new engine which is 20% more efficient for the Cessna SETP.
If two engines really are more efficient, why has the SETP come to dominate? What about the physics changes?
Lastly, look at the practical range of the SF50 and the SR22. 300 - 700 miles is likely the sweet spot. Around the major metro areas you are held low. What is the fuel burn on your older twin TP when you want to approach KTEB flying from KRIC, and you are held at 11K for the last 200 miles.
With the majority of SR22s used flying between major metro areas or one end of a flight near a larger metro area; you see the majority of jets and TPs held low for a significant portion of the flight. I would expect the same to be true for a large portion of the SF50 planes. So the high altitude penalty you keep mentioning plays a smaller factor, and the additionally benefits are significantly mitigated.

Tim 100% true. I only file to FL210 when flying Atlanta to NYC because they're going to have me at 17K' at Washington DC and then 11K' and then 8K'. IN and out of Atlanta it's the same story. In and out of South Florida it's the same story. You see, above 18K', It's not "up to you". A new Eclipse costs $3.2MM. Not $2MM as has been said in this thread. You guys that poo poo'd the SF50 6 months ago and said it would never go faster than 220 were wrong and you're going to be wrong again when the SF50 dominates the market.

With thier pistons Cirrus was at the top tier in terms of performance and innovation. With thier jet they are dead last place in terms of performance but do have funky innovation with sacrificing all that is good about two engines in order to make one engine work. This jet is going to be sold to piston pilots, not jet pilots. My guess is they will sell well to the affluent piston crowd. Peronally, I would still like to see something along the lines of the SJ30 but that niche looks pretty dead.

But Erwin, then these "piston pilots" will BE -----> JET PILOTS!

By jet pilots I mean guys who are currently flying at or over FL400 at over 400 knots. I don't see those guys getting excited about the Cirrus Jet. For any piston driver, yes the thought of 300 knots and mid twenties flight is exciting and rightly so.
Anything from a C172 on upwards starts getting a guy out of the commercial airports. I do not even consider commercial anymore. I'll just stay home if it's not the Merlin or C182.

Those guys aren't buying one. That's NOT where the market is. How much faster is a 400 knot jet flying ATL to TEB going to be over a 300 knot jet? You're not getting to FL400 anyways. It's a silly thing to keep saying.

Username Protected wrote: This jet is going to be sold to piston pilots, not jet pilots. I've been told by guys at Cirrus that there target customer is the guy that bought a new Baron 30 years ago. I think Jason and Erwin are, therefore, both correct. There are a fair number of pilots who went from an SR22 to Eclipse, TBM, Mustang and perhaps a few to PC12's. Not too many who, after flying a modern airplane went to a legacy jet or TP. Cirrus will shortly have a product that appeals to many of their existing customers (and they probably have had over 10-15,000 so far with resales) and is in fact designed for them. Whether the plane is a perfect long range aircraft, costs more or less than some aging TP, is inferior because it only has one engine, etc. is clearly irrelevant to the marketplace which seems to have hundreds (more than any other turbine aircraft in existence - probably more than all other turbines put together) of people willing to plunk their money down. It's the same story as the SR22 which is clearly an inferior aircraft to all its competitors which is why only 6,000 or so have been sold in the last 14 years and why every airplane they produce is sold with relatively long waiting lists.

Mike C. Eclipse was a new company trying to fly a proven mission with unproven technology. They fell on their face. Cirrus is a proven company using (best I can tell) proven technology to do a mission that people have heretofore ignored because it was thought inefficient. So we might think it's a "bad" airplane, but there isn't much other that prevents someone from making it. All Cirrus has to do to succeed is get people to buy it. They're devoting their formidable marketing engine to sell buyers on the planes "inefficient" mission. I think Cirrus has far better chances than Eclipse.
