Looking for fuel flow of a CF680C2B at takeoff thrust, sea level, standard day.
Thanks

To start, I would take it's takeoff thrust and multiply by approximately .34, it's (also approximate SL, 0 KIAS, std day) SFC. That will get you close, others here I'm sure
will critique and fine tune my admittedly quick and dirty formula.
