I'm wondering if any of you pros out there can tell me the average fuel burn for a 1974 Gulfstream II. I've searched high and low for these numbers on the internet, but can't seem to find anything. I'm trying to do a cost analysis between this aircraft and several others. Thank you very much in advance!

Have you tried ARG/US? I know they offer these kinds of comparisons, but they do charge. Also I would call charter operators who operate these aircraft, they could give you heads up on other info like Mx, AD's, and other quirks.

Fuel burn? A lot...

Try Conklin de Decker...they've got all the economic comparison info you could ever want, for a price of course

6000 first hour. then 3500, 3300, 3100 & 2900. Then land.
