Just out of interest, AD-PLC is the PC12 always within a gliding distance of somewhere safe to land? Just curious is all.
Yes. From FL180, glide range is re 40-45nm. ie. 80nm between suitable sites is fine.
YMLD (Maitland) - YSPY (Spilsby Island) is 69nm, with YPLC a further 23nm away. And there are plenty of perfectly acceptable landing areas on Yorke Peninsula that would be closer than that.
Just to get Wally excited, one of our aircraft went YPAD - YWYY (Wynyard, TAS) earlier this week. From FL270 / 280 the aircraft is always within glide range of an airport or suitable site, even on that flight.
