To P or not to P, that is the question

Thanks for the reply. I flew cargo and pax over the Rockies for a 135 operation in some (unpressurized) Navajo's, so I am familiar with trying to go down and slow down without shock cooling, as well as operating with oxygen.

I am also hoping to find a 337 w/ Gami injectors and run LOP. It seems like I should be able to fly 1000nm in the high teenes with a bit of tailwind if I have an aircraft w/ the long range fuel option.

I am sold on inline thrust and turbocharging for my family missions out of Denver, and yes, the 5th seat is for future kid.

Do you think that you have higher insurance rates with the pressurization than without?

Are there any required annual recurrent training requirements that you don't see with an unpressurized 337?

Thanks
