CRJ7 Fuel Burn

[Joshrk22]

Does anybody have CRJ7 fuel burn rates? Like in a chart? I want to put the data into Fltplan.com.

Variable at different N1 speeds and altitudes...
I would stick with 2*xz((x/6.7y+z)(17-6qx))=pph
It always comes out perfect

At altitude, about 1500 pph per engine.

Around 20k its ~ 2000 pph

I figger' about 4000 lbs/hr first hour & 3200lbs/hr thereafter; 3000lbs/hr to do 250KIAS roughly at any altitude; 2600lbs/hr holding at 225 clean (about 2300 @ 210). Umm...and about 500lb/hr/eng taxiing (if it comes to that taxiing around ORD).
