'A69" that's a loooooooooong bow yr drawing there but I hear you. Some of the RFDS work is contractual so it matters none what airframe type is used there's still x amount of airframes allowed in that contract for the bucks avail. Everything is predicated on 4 airframes.Tech Crew, maint, general staff & of course the resource which is often not enough, the Ambo's. Having 5 PC airframes as they would cost the same as 4 B200's (which I doubt very much) wouldn't mean all where avail at any one time.
I know the Vic contract never allowed for SE planes when it finally was drafted up, one reason early in the peace was that the Ambo's union I believe wouldn't allow their members to fly in SE planes, fair call I reckon:-)
Remember in Vic AAV use ambo's (an extension of the road guys/gals) where as I think all other places use employed RFDS staff,medical wise.
'C Stally' yep the old broken record has been dragged out again

as it's bin a little while since we had this debate & I thought I might not be able to 'spin-up' the old song but like the sound of a "twin" I'm on song

Again at the end of the day as I have said a zillion times b4 it's about choice, I simply wouldn't fly in a SE plane at night in IMC, I value my own life just a tad more than those who do take that risk:-)
10 yrs for me & EVERY time I took off I thought ....ahhhhhhh there's nothing sweeter than a twin engined machine out of sync
I hope we only ever go back & forth here using just words about 'what if ' & not "I told ya so"!
