Mike if they had made the SF-50 with a single turboprop engine in it, would you change your opinion of it?

Yes, because it is achieving good performance for its type, not sucky performance for its type, and because you wouldn't need a type rating, or an inspection program to operate the plane. It would also have far better runway performance, and be more controllable in speed for transitioning piston pilots. It would cost a lot less to operate.

Could they have gotten 300 kts out of it?

TBM did, so possibly. Certainly should reach PC-12 or M600 speeds of 260-270 knots.

Mike C.


1. What is the type?
2. The SF50 is about the same size as the TBM. The original TBM is about the same speed. Why do you make the assumption that the first generation of a SETP would be faster/better?

One wonders how much of this is Williams money, and if this represents an introductory offer by Williams (which they have done in the past for some types).

It is easy to have a reduced rate at the start for both the engine and airframe, all the parts are new. It will be interesting to see how this pricing changes over time.

Mike C.


Precisely.

Assuming $4/gallon and 20k for insurance/hangar, that's an all in cost of $670/hr. Pretty darned good for 300 knots, I'd dare even say comparable to MU2 operating costs. If they can keep it there.

Give me a twin TF50, no chute, and that airplane is safer than the SF50. No doubt in my mind about that. And then, as a bonus, it is also faster, farther, and cheaper.

Cheaper to operate per mile.

Similar cost to make.

No way Mike. You've been claiming this entire thread the 2 engine SF50 would be cheaper to manufacture because Eclipse.

Also, the 2 engine version wouldn't be "cheaper to operate" because it would cost 2X more to buy and depreciation alone would be close to $1K an hour.

$670 all in, minus $333 program cost leaves $337.

200 hours at $20K for insurance is $100/hour insurance. That leaves $237 per hour.

At $4/gal fuel, that works out to 59 gal/hour block, which is not plausible. Block fuel flow will be ~85-90 GPH. The jet engine burns a lot down low and the SF50 does not climb well, so it spends a fair amount of time down there.

Also, no hangar, taxes, cleaning, fees, consumables, etc.

I'd figure:

$333 program cost
$340 fuel at 85 GPH at $4
$150 insurance ($30K/year, we are dealing with a transitioning pilot)
$50 hangar ($10K/year, varies wildly with locale)
$75 misc (cleaning, taxes, fees, consumables)

$948/hour

200 hours costs you $190K.

This didn't include training costs.

A 100 hour/year plan would be quite a bit more per hour.

Conklin and de Decker does a pretty good job I think of giving relative costs of planes. Not everyone accounts for stuff the same way, or would operate them identically. However, they are good for showing the relative costs between planes.

As of the end of 2016, here is the report AOPA licensed from them:
https://www.aopa.org/news-and-media/all ... ting-costs

You will find Cirrus SF50 is right round $600 per hour.
This number is consistent with what others have posted in COPA, and a few other comparisons. I believe most are using between 200 and 300 hours a year.

The math doesn't work at $333/hour for the programs. You can't pay for everything else in $267/hour.

So the $600/hour number fails sanity check.

Concierge includes the training.

Throw on an additional 6 gallons/hr @$4, and let's round it up to an even $700. Still pretty competitive.

I do not know if Conklin and Decker use the engine program or not. I just know that they have a very solid reputation for relative costs between aircraft. Years ago they came very close to the relative difference between my Cirrus SR20 and the Aerostar, and against an acquaintances SR22 to KA-90.

As such, Conklin and de Decker shows Cirrus to be the cheapest jet by a significant margin, and very competitive to the SETP and much cheaper than twin turboprops.

Wow, they must eat really nice on that plane! ~$30 bucks an hour for food!
But they pay the flight crew really cheap, ~$40 bucks an hour.

Anyway, I think they are great for comparing planes.

It's a good tool, for sure. We use it daily.

I really threw that PDF on here just to help us get to 500 pages........ :duck:

It's a pity Sean doesn't get some the ad revenue for starting this thread. He'd be able to get in line for his SF50
