8000 kg's will put it just under the cut off for larger aeroplanes under the new reg's, perfect for the RFDS.
The announcement of the PC24 was also timed 1 week after the changes to FAR 23. They know exactly what they're doing.
There is still talk of an Aeromed section (as opposed to RPT MT), it's going to be a long road for the policy makers.
400kts (assuming thats a standard cruise) is not that much slower than other Jets in class but it's more then that, it's the sealevel cabin to 23,000ft (I can only imagine flogging about at 13,000 between the Pilbra and Perth isn't fun in the middle of summer), its the 30min time to 45,000, the short field, the unimproved strip, the door, the modular cabin, over and underwing fuel, common engines, ground power (assuming it can be certified without a pilot on board), one touch cockpit and full automation. They achieved the figures with the PC12, hopefully they can pull it off again with the PC24.
