Hi SBC,
Are u taking a stab at anyone in particular? still being the loyal servant?
You might wanna fly a 1900 one of these fine days
The 1900 does gravel quite well provided the surface is not too rough or undulating etc... The height of the intakes is not much different from the caravans, so inertial separation is more or less the same.
Only problem in my opinion is runway length if you stick to book V speeds (as one should when they fly in the bush, or anywhere for that matter)
Cheers gals and guys...
