Realistic CJ2/CJ2+ numbers?
I know there are some good CJ2 guys on here, so this is what I'm looking for:
What are some realistic range/payload numbers for the CJ2/CJ2+? Lets say 3 pax, 2 crew... can you do a 1,000NM leg in the winter with an average of 50 knots on the nose?
We operate a citation I-SP with the Eagle II modification and their published numbers are turning out far from realistic.... didn't know what others had to say about it.
I'm new to the citation world, so thank you in advance!

I cannot elaborate on the CJ2 (maybe minitour can?) but yes, the CJ2+ can easily fly 3 pax 1000nm against winter headwinds with two crew.
Our 2009 CJ2+ has an empty weight of 7766lb and a two-crew BOW of 8125. With full fuel (Cessna says max usable is 3960lb, we often see 4000lb when topped off), we have 500lb of payload available to get us to the max ramp weight of 12625lb. 600lb of fuel is 45min IFR reserve and 800lb is good for 100nm alternate + IFR reserves. At FL450, I flight plan for 402KIAS and 730pph but observed TAS typically runs 406-411KIAS.
Our heavily tweaked Fltplan.com profile tells me SDF-ASE (998nm great circle) this afternoon @ FL430 would be 3+10 with 2709lb fuel burn against an average 56kt headwind; cruising wrong-way FL450 (which we always ask for) would save you another 100-150lb and result in no additional time enroute. With 800lb reserve, we could easily carry 4 pax & bags and maybe 5 passengers in our airplane, depending on their size and how heavy they pack.
If you'd like, I can run fltplan.com flight plans for a couple city pairs for you...

Yup.
I think the "straight" CJ2 has an initial altitude of FL430, but the CJ2+ will do sea level to FL450 in 25 minutes @ MGTOW on the 230kt/0.55M Cessna profile - we normally take closer to 30 minutes but climb at 0.58-0.62M because acceleration is a bit sluggish when you level @ FL450 at 0.55M, especially if ISA temps are warmer than ISA+5.
The difference between FL410 and FL450 in the CJ2+ (and CJ3) is only a couple knots of TAS, but over 150pph fuel burn.
