I'll take a look at the Legacy 600. Thanks for the suggestion! Looks like it was based off the ERJ series aircraft which was the general area we're looking at.
As far as payload goes, that is variable, but I'll check. After looking at the data and seeing a difference of about 4000 lbs between max total fuel and max fuel with max payload, makes me wonder what the fuel burn during cruise is? I imagine 4K lbs is at least a couple hours of cruising in the 400kts range?
Also, I'm sure the 4000NM requirement may rear its head occassionally, but hopefully it won't be an everyday event.
Are the runway length estimates for the 604 accurate? Bombardier advertises lengths below 6000 ft, which would allow for quite an array of locations. Anyone know the CBR or any other restrctions/options as far as types of fields? I'm sure semi-prepared is off the table?--gotta ask, even though I know y'all will laugh at that one for sure.
