They have the Williams engine, control most of the type and recurrent training, as well as avionics, databases, communications, parts and labor. Not to mention sales. I really need to find me a business model with mandated vertically integrated recurring revenue  Cirrus for the most part, even with Chinese owners and money is doing well, which is good for aviation and development. It works for them and apparently the large customer base they have built seems to be okay with it. When people stop buying the Jet or their Pistons they'll adjust.

Flew from Ft Lauderdale to Columbus today. FL330. Hot (+15 to + 18j. Approx 350 KTAS 600kb/hr. At some point ATC gave me a a slight turn for climbing traffic. I started watching them climb on ADSB. We are heading to the same waypoint at this time. I noticed it’s climbing really slow and I’m gaining on it by 30 knots. I am not accustomed to this. Typically at this altitude others are climbing and separating by 50-125 knots. That plane is eventually in sight - and ATC confirms it is a Citation -a 550. Once they leveled at 350 and finished accelerating; our GS was essentially the same. I was most surprised by the slow climb 14 minutes to go from 310-350. We climbed from 290-330 in right around 5 minutes, but we’re 40 kts slower in the climb. We flew 880 nm in 2:45. They flew 1080 nm in 3:15. So, legacy Citation on a very similar flight. Essentiall the same time. I burned 1800 lbs, I wonder what they burned? They filed for 390 but didn’t get higher than 350. High ISA temps limit climb? My guess is they have lower cap costs and likely lower maintenance. They probably win $/mile. I win on fuel costs and carbon emissions, most landing/facility fees - and my cabin might be a little more comfortable. And it’s unique. https://www.flightaware.com/live/flight ... /KFLL/KCMHhttps://www.flightaware.com/live/flight ... /KPBI/CYYZ

So 30 minutes faster for ~1200 lbs more fuel. The planner is at MCT. I'd probably back off a bit and time would be 2:20 and fuel would be 2830 lbs. That would net 24 minutes faster, ~1000 lbs more fuel. I don't feel the need to use MCT all the time. My MCT true would be ~410 KTAS, backed off about ~395 KTAS. Depends on weight, of course. Temps at FL400 are showing ISA + 2, not a big deal. On this short a flight, my weights would be such that I could use FL430 or FL450 and get my fuel down further. I tend not to do that, but it is an option. Quote: They filed for 390 but didn’t get higher than 350. High ISA temps limit climb? 550 is better than a 501, but still not a fantastic performer. Should be able to go 370 KTAS, though. Might have been heavy. There are gross up kits for the 550 that can elevate the max weights pretty high, and that makes it wheezy at high altitudes. Quote: My guess is they have lower cap costs and likely lower maintenance. They probably win $/mile. I win on fuel costs and carbon emissions, most landing/facility fees - and my cabin might be a little more comfortable. One comfort is being inside the plane less time. Quote: And it’s unique. That it is! But it isn't a jet! Mike C.

Username Protected wrote: Putting this nice little Citation V into prebuy at a gold plated shop tomorrow morning! Looks like 560-0092, N592VP, presently at KMQY, Smyrna, TN. I'd surmise the shop is Stevens but Contour also operates there. They have the $20K Skystep, which is nice. They could save a ton of weight if they pull out the tubes on the panel, plus get rid of the pedestal, makes things awkward up front. Beware of the gross weight increase mod (ups MGTOW to 16,300 lbs). It lowers the landing gear life, check that the tracking shows this (think it becomes 11,425 landings). This plane has a pretty high ratio of hours to landings, so not yet too close to that, but when it comes, the cost is a doozy to get new main gear legs. My plane does NOT have this mod, and I get the net effect of it by the Garmin upgrade, dropping 380 lbs. The quick release radome is kind of nice, but it really only takes a few minutes to take the nose off without it. The inspections are out of sync, phase 1-4 due in June 2024, phase 5 in October 2024. Would you tear the plane apart that much just 6 months apart? Tough call on that one, doing a phase 5 early is annoying, too. More total time than mine, but that's no big deal for a Citation. Mike C.

So you fill it up (5770 lbs) at about $5/GAL is roughly $4300?

You will only see that if you have 0 gallons usable on board, which should be rare, hopefully, or your last flight was more exciting than you wanted. Most of my fuel receipts are in the $1-2K range, occasionally a $3K. A full tank goes a long way and saves money. For example, KDTS has expensive fuel, almost $3 more per gallon than my home field. I don't need to buy any to go there and come back. Mike C.

Thanks
So appropriate $/mile?

Not exactly what you asked but easy math is about $1/lb so if you know fuel burn in lbs that's an easy way to gist fuel costs, adjust slightly down depending on how much you spend on fuel. These days it's often not far off.
We've spend about $50,000 this year on fuel in 150 hours. The simple average is about $5.80 gal, I don't have gallons for every receipt so not sure the correct weighted average. That works out to about 380lbs/hr though which is about right. We can carry about 8 hours of fuel so tankering helps with costs.
380lbs / 300 knots = $1.25/mi

Username Protected wrote: Not being on programs only wins at the end of your ownership if you’re up financially. How do you know what will happen to your engines on tomorrow’s flight? I don’t have a crystal ball, but I don’t worry about the financial impact of that. Will I pay more in the long run?  All I know is what it costs me now. There is definitely an insurance aspect benefit to being on programs. If you are a corporate user, accountants like regular cash flows vs lumpy ones, even if it ends up costing you more in the long run. Also, some programs include benefits like rental engines and such so your downtime is lower. Again, this has a benefit to a corporate department. Just keep in mind that, like with any insurance, if you underpay then the insurance company goes bankrupt. So I can guarantee that you are overpaying. But if it works for you (and if you can write it off as a business expense) then go for it. But as a private/recreational user, I would like the option. So unless something changes, I will stick with JT15Ds and eat the higher fuel burn in exchange for lower maintenance costs.

Username Protected wrote: 380lbs / 300 knots = $1.25/mi Ahh, The power of the 441. I suspect the V is easily three times that. The point Im trying to make is that if you want to fly a jet at some point money really doesnt matter that much. maybe capx. Yes. But these birds are expensive to fly. Engine programs are almost a minsicle part of the overall equation and also maintain at least some value in your engines.
