Mine weighs 515 not counting the dog. 170 gallons would give you about 800 mile range with IFR reserves. drop 20 gallons and you gain back another 135 pounds. Probably burn 10 gallons in taxi time... or fly over gross which seems like everyone does. Meridian feels like a 4 person, 600 mile airplane to me.. any further you make stops every 2.5-3 hrs which you probably need to do anyway because no potty. Adam your boys will grow a lot in the next five years and you will need more luggage space and useful load. When your start up kicks in you will rocket past STEP's look for a Jet.

Or increase power in a headwind knowing an intermediate stop will be needed? Or know that altitude is speed, CAS is range? Is there so much to learn with these airplanes that guys aren't curious to analyze the basics? Even to extend TBOs? Not saying I know better, just really curious.

I do almost none of those things, choosing to focus my effort more on risk mitigation.
Some fly LOP, but many don't due to the effort required on a GTSIO to get it set up and the availability of operating at peak at 55% power. Also in a given year my mx expenses might be even money to be more than my fuel expenses. It's very possible the extra time on the plane and engines isn't worth the efficiency you gain going slower. Unless I need the range to avoid a stop I am at my max cruise.

Poor guy asks a simple question and all he gets is "Don't be such a flipping idiot - fly fast!" While that advice is certainly worth mentioning, it would be nice if a 421C owner with a real POH would add "But if you insist squeezing the absolute maximum range out of the 421C, you set..."

Those guys are too busy reading the turbine sales ads in Controller

From a 421B POH, but should be very similar Maximum still air range is quoted at 1350nm at FL250 at 55% power with a 45 minute, 45% power (20 gallon) reserve. 555 power specs at FL250 are 200 KTAS/31 GPH PM me if you want the whole POH

I won't use your math, but I'll take a little of your programming expertise Insurance (11,500) Hangar (15600) [My residence at tRide is saving me money, FXE is expensive] Annual (45,000) [Included a new AC unit and brakes, which I knew would come in my first annual) Maintenance (2,800) [Replaced the inertial separator] Fuel (95,000) [Actually came in a little lower than that but I have longer trips and am normally always above 25k] So my operating cost last year was $377 an hour. Add another 140 per hour for engine reserve and I'm below the $600 mark. Throw in HAPP at 17k and I'm right aroun $550 per hour.......... To top it all off, that airplane has been reliable as all heck. Only had one issue with a nose strut seal failure that dumped the hydraulic fluid out of the strut, which was when I landed at 30GA on my way to my annual. There had been a very slight leak in the previous flight. I believe that's why the PC12 is do damn desirable and holds it's value so well.

Michael what was your total dollar cost for last year ? How many hours did you fly last year?

I flew 450hrs last year in my PC12. Total of 525 in all airplanes. Most I have ever done. What was above, except my fuel was 86.4k. I do however had KACT where I get my fuel in the 1.80 -2.10 range. I fill up there once a month on my fl-tride flights. Operating cost of the PC12 has astounded me as it falls inline with what others have been preaching. If you have your own maintenance department with a fleet then the operating cost is very little.

Username Protected wrote: 500 hrs is no joke. How many did you fly in the Baron. At 500 hrs my plane can be flown for lunch money...  only a total of 8hrs. Baron was sold earlier on this year. Only have the PC12 and Mooney. Did another 30hrs of flying in another PC12 and then the rest was Mooney and helping gravel bar Larrabure bring his 182 up from Costa to Seattle.

Michael the PC12 is very nice and if I had a need to fly 120,000 NM per year I would have one. I only need 20,000 to 30,000 NM of transportation per year. My total yearly budget is about 60,000 dollars per year. Yours is more than 250,000 dollars per year and this does not include the capital cost on Three Million dollars. the hourly cost for a PC12 at 100 hours per year would be more than 2,000 per hour plus the debt service. The PC12 is a great family plane but you need to fly it a lot and have a budget of more than 250,000 per year. The 421C is great for pilots with a budget less than 70,000 per year. The big problem is it's getting harder to find good 421C's. If I was 45 and my kids were still young I would have a PC 12 in my hangar.

Gerald, no doubt and I agree with you 100%. But you can afford that airplane, it will appreciate  , and your wife called and told me you can get one!!!! I looked long and hard at the 414/421's and eventually decided that the capital cost warranted the PC12 given the hours I would fly. I surprised myself by flying a ton more, simply because I had a tool that could do so.
