Ciholas Proclamations:

The SF50 will never go faster than 220 knots
The SF50 will never be certified

Everything else is just debate about personal preference. Some of you guys think aviation revolves around the 1970's. Others don't and the market supports this.

If some of you guys were as smart as you think you are you'd be living in Northern California and flying in the back of a G5.

US Government or Chinese Government?

I do wonder if the Chinese bought Cirrus because they want a lot of SF50s to create a transportation system in China, which they need.

I do not believe that all the Chinese investments in aerospace are because they think the US market is going to make them lots of money. I believe China realizes that General Aviation is needed to get economic mobility around their large country as it continues to develop. They intend to bring their aerospace investments back to China when the time is right.

Really?

They wash out Cirrus buyers if they can't meet the ATP PTS standards? Fly an ILS to ATP tolerances? Hold heading and altitude to ATP tolerances?

I call shenanigans on this one.

I don't remember Mike C posting either of those assertions, but I'll let him correct you.

That said, 220Kts IAS is probably very optimistic for the jet that's touted as the "Lowest & slowest" !




Really, what about the Eclipse ? Seems it's THE most recently certified VLJ of the Century !



Once again, rather than playing the "ball", you continue to play the "player" ...

Oh, plastic is just as light as you want it to be. But I read somewhere, and have been told this also, that with composites the FAA is assuming a 50% reduction in material strength due to defects in manufacturing. So all composite structures must be manufactured to twice the stength requirements about the usual design margins...

And that the data used to substantiate this position is from the 50s, and the FAA has no interest in updating/changing the position.

What am I wrong about?

What does the Eclipse have to do with what I said? I like the Eclipse. The Mustang is a VLJ. So is the Phenom 100.

220 kts IAS or TAS at what altitude?

220 kts IAS or TAS at what altitude?

Sounds like a good theory, but that guy is going to have to train to ATP standards, get a type rating, go to recurrent every year, and manage a 300 kt airplane in the flight levels. It ain't the same as an SR22, even with only one engine.

Those are lies, previously stated by you, previously noted by me, so I conclude you are rudely doing that on purpose now.

Your ability to state the opinions of others is so bad that I suggest you never try to do it again and limit your comments to what YOU think.

Pot meet kettle.

The point was to show the lever count. The LET 200 is perhaps the world's worst piston twin for having so many levers, all the same color, mostly all the same shape. It would deserve mention in any book trying to show a bad human interface.


They have all that in the SF50. The 375 knots and FL410 occur during the easy part, cruise. All the other stuff, working in busy terminal airspace for example, is the same. The faster airplane is NOT going faster at the same altitudes, only up high.

The profile of these SF50 buyers put forth by the proponents seems strange to me. They are intimidated by a second power lever, and apparently any cruise speed over 300 knots, but yet are going to fly predominately between TEB and PDK, two very busy terminal areas crowded with lots of big iron GA, and have no problem at all getting a type rating. What a weird mix.

I just do not think having a second power lever and the ability to fly higher, faster, farther is that intimidating.


Because that is all that they could do once they made it a single. They are trying to characterize the main defect in the airplane as a feature. They are trying to turn "limited" into "simple" and it really isn't.

Believe it or not, RC planes push WAY beyond 25,000rpm. I've got a bunch of RC planes that will push 40,000 rpm, most of them are pusher props, but a few are normal setups.

The most popular is probably the Multiplex FunJet and with the "recommended" stock setup you get a 3000kv outrunner motor running on 3S and a 6x5.5 prop. But most people run inrunners faster and on a 6x4 prop. However we don't measure in RPM, we measure in heat, amp draw and sound (louder is NOT better). Stock FunJet will run about 120mph, modified around 140mph. Prop speeds are around 600mph and do a ton of damage if you don't throw it correctly on launch!

Chip-

Somewhere between FL250 (which the regulations support easily) and FL280 (which Cirrus has proclaimed).

Anything else would be a major surprise.

Higher than FL280 would require substantial redesign of the airplane, and trigger RVSM requirements.

Lower than FL250 would be even more stupid than it is.

"Nobody knows" is just wrong. We know within a fairly narrow range.
