Well this is not something I am looking at tomorrow, potentially in maybe 2-3 years.
But I just find it funny how with the GE powerplant the PC12 would still be better than the Denali in specs, except for an extra 3 inches of cabin width!
But yes, definitely would not look at a powerplant conversion until it gets CASA approval.
Where did you hear about FAA ditching the S/E charter? On an unrelated note - I also heard EASA just approved it recently!
