Zeke. .I agree on all your points. The PC12 glides at about 2.5 to 1. That is it goes 2.5 nm for each 1000ft of height lost (the B200 is 2.0:1). I believe Central Section RFDS use the standard glide to intercept a 1:1 descent profile to a selected field and maintaining this 1:1 gives a speed of about Vne. They hit the circuit at this speed and theoretically have enough enertia to carry out a full circuit and land.
This of course assumes the runway has PAL lighting and that you are visual. If either of these does not occur, well, you can guess the rest! A PC12 after departure from SY should always be able to at least clear the mountains in a glide. The glide speed is less for a PC12 than a B200 and the stall is less than 70kt. A King Air stalls at about 86kt (Raisebeck), a big difference.
Pilatus have done a lot to give the occupants of the aircraft every chance of survival in an emergency landing in the bush. The point is you don't want to go to the bush, you just want to go home! The PC12 cannot be as safe as the B200. PERIOD.
