They are cracking airplanes though
And they look dead sexy (I especially like the F50) and I want to fly one.
Oh well, me and my dreams.
As for the sov, well Cessna stated sumethin like 2847nm (with 2 pax IIRC) for the now "old" sov and one might be able to squeeze that out of the airplane, but I´m a firm believer of having at least one 'backdoor' open and that for me is that I plan on FL430 and not 470 + HSC (to have FL470 and LRC as a 'backup') on long flights and with the alternate situation and sometime very wide areas of bad wx I wouldnt plan the sov on more than 2300-2400nm...
Cessna themself say 2500nm with 2000lbs payload at zero winds, HSC & 200nm alternate (again: old sov)
And with 6-8 guys in the back the sov is stretched in every sense. (IMO) The numbers of the new sov are preliminary btw...
There is the range vs. payload graph for the new sov:
Performance & Specs
If you look at the second graph - flight planning, they say fuel used for 4 pax, HSC, optimum altitude and 3000nm is roughly 10000lbs - that would leave you with 1348 lbs (nev Sov max fuel is 11348 vs 11223 of the old)
Thats not enough for comfort in a Russian winter secenario IMO.
We sometimes do trips like HTDA-HESN-EDFM (3800nm) or the like and the difference between having 4 or 6 to 8 pax is very obvious.
Ours is probably one of the lightest ones I might add (DOW 18139lbs / includes 80lbs galley and 30 lbs maps) , meaning we can have at a payload of 1188 lbs at max fuel (11223lbs).
We use 212 lbs for a male pax, so we could have 5 pax with 128 lbs of luggage on board.
The new Sov has slightly higher weights but I guess the 2 mtr of span will weigh something too.
