600 vs 900 vs 1200 hp is basically the story.

Why does a 206 cost more than an 182 than a 172. Fuel, systems, maintenance. Just bigger, more complex planes

The big block pt6’s are $$$ more to overhaul

But seriously look at a 172 vs 206. Or a 20’ boat vs 24’. Size matters, size brings complexity and cost

The easy, golden rule of GA plane costs:

1$ or €/hp/hr.

Try it, you‘ll like it.

I agree. More cost to overhaul a big block PT6. But that is overhaul after 3600 hours. More to purchase too. But to maintain, year over year? What is the difference? At the risk of saying size doesn't matter and my wife reading this, how does size increase complexity on the SETP? Same engine accessories. I would say the G300 avionics and Garmin Autoland are more complex on the M600. Same de-ice systems. All have pressurization. Retractable gear. I really don't see why size should matter here.

1200hp requires roughly 2x the fuel that 600hp does. So fuel costs are roughly double.

As we used to tell the new guys, that is the speaking tube

They work, no smelly relief tube left in the cabin, no relief tube port on the outside of the airplane, and no airframe corrosion from urine. My plane came with a relief tube, and I removed it.

I consider it safety equipment since it can remove a very strong distraction. There have been scientific studies to show needing to go approximates being drunk in terms of mental impact.

This is a huge factor.

The PT6A-6x engines can cost $500K to overhaul. The small block engines can be half that.

I saw an invoice for a Cheyenne III with PT6A-61 engine overhauls that was about $1.1M. That was back in 2013!

A PC-12, despite having only one engine, costs way more per mile for engines and fuel than my twin engine MU2. Two engines is not necessarily more expensive.

The M600 engine will be a lot less costly to maintain and fuel than a PC-12. Just being larger means everything costs more. Tires, windows, gear parts, etc.

I love Travel Johns! I swear by them and they make my long legs possible!!

On the MX costs, most (but not all) of the M600 maintenance is on condition, rather that based on scheduled MX intervals. I think that’s one big difference in the cost expectations. There are some life-limited items and inspections, but for Part 91 operations, there are relatively few of those. That means more flexibility in managing MX costs at annuals.

I believe that’s true for all the PA46s but can’t swear by it as the 600 is the only one I have owned.

Last time I went to order more travel John’s I saw they have a new version with a zip lock at the top to seal it off after use. Works nice.

Nice sure why but I need to pee more often when I fly then on the ground.

I had a recent flight where I overheated my heater and was super cold. FL250 and -33c I had to fill 3 travel John’s on that flight. I could not believe how much I went. So apparently being cold at high altitude makes me pee more often, who knew. Haha
