For ATR72-200 series first hour fuel burn reckon on about 700 kg/hr, thereafter about 600/hr. For the 500 series add around 100kg to these figures.
The 72 has 2 stages of flap, 15 and 30 degrees, unlike the 42 which has a third guarded setting of 45 degrees for emergency use only.
The config call outs are Flaps15 and Flaps30.
I have not seen any performance calculations for a flaps 30 take-off, but that's not to say there aren't some somewhere...this would be distinctly non-standard.
