i'll have another go...
Hello Overrun and Mutt
I begin to see more sense.
Is it more like this?
Cd0 = 0.01300 typical
Cdi = CL^2/24.38
Cdc = 0.0015 typical
OEW =168.0 tonnes.
Payload = 250.0 tonnes
ZFW = 193.0 tonnes
LDW = 203.0 tonnes
TOD = 204.0 tonnes
TOC = 294.5 tonnes
TOW = 301.0 tonnes
GS = 442.5kts
tsfc = 0.55,kg/kg-hr,
L/D = 20.2 typical average
Climb 122nm
Cruise 5968nm
Descent 130nm
Total 6220nm
Trip fuel = 98 tonnes
Trip time = 14.4hrs
The wing would have to have an aspect ratio of 8.7 and an Oswald's "e" of 0.89 for example.
Anyway nice talking to you
