Great work Tony!
Do you have a version of the spreadsheet that includes formulas? Each copy I download is basic number formatting only...

Unfortunately no. I am downloading it from the software and the formulas aren't included.

Greg-
Insurance is going to be driven by hull value and not going to appreciably differ between the Meridian and TBM unless the asset value is substantially different. They both are pressurized single-engine 6 place turbines. They both share roughly the same underwriting rate tables (again outside of the hull values). Obviously pilot time in type affects the rates as well but the aforementioned assumes the transitioning pilot has no time in either type.

For comparison purposes would be best to put as many line items the same such as hours flown, hangar cost, etc... ? MX and fuel burn would be the big variables.

Tony,
FWIW All the turboprop's long range cruise speeds are less than 250KTAS if that's important to you.

I thought that as well Jason and think you are probably right. However, I took the figures from JetAviva's Market Report for the Fall 2015 here:

http://www.jetaviva.com/market-reports/ ... all-15.php

I assumed that they are tracking the market (they certainly claim to be). I realize most assumptions are faulty…still, the interesting thing to me about the PC 12 market report is that it supports what you have said a number of times: Pilatus' are not depreciating.

If I increase the purchase price of the two PC 12 versions by $300,000 it increases annual total cost by $20,000 mol. So not a big deal in the whole scheme of things.

Not really, at least for the TBM's. Their long range cruise numbers are 35 to 42 GPH and right around 250 KTAS (exceeding in some conditions, not in others (temps and altitudes)). Any of them will easily exceed 250 KTAS for an 800 NM trip. Not jet speeds, but fits some missions nicely.

How did long range cruise come into this? Most of the tprops listed can do the 800 nm trip at normal cruise speeds.

A couple of comments have made the point that age of the plane, its equipment, etc. impact acquisition price and of course that is correct. Also, how the planes are operated affects cost as does mission length and a host of other variables. BUT this analysis assumes averages. I was interested in "ball park" cost figures so that these could be ranked and compared. If one was looking at these planes as the options one could then take the most attractive, from a cost point of view, and then further analyze desirability of speed, number of seats, potty, jet vs. turbo prop, landing distance and a host of other variables which are all more or less important. This can go on forever of course!

To me the most interesting thing in this exercise was that almost all of the airplanes are within 10% of each other in cost (bearing in mind the assumptions of the exercise).

Which tells you how wildly inaccurate it is! In other words, I don't see how this list can aid in making an aircraft purchase decision.

I agree.

I looked at the Annual Budget figure. I didn't even use a calculator just eyeballed it. It certainly looks to me like all the planes in the analysis, flying roughly 50,000 miles a year cost a similar amount of money. Not enough in my opinion to pick one over the other particularly. For that we will need a scalpel!

Yes, you can buy any given airframe for a wide range of price. That wasn't the point of the exercise. My intention was to try to look at cost in general terms, by category of expense and in general terms using someone else's data that I wasn't manipulating (perhaps they were I don't know!). I only included the MU's because someone else asked me too. I could include the lower cost versions except that aircraftcostcalculator doesn't have them in their database.
