But climb rate is not the only thing. What is the speed during climb? The SAAB2000 would outclimb the CRJ. But not really. Different things. Gradient vs. rate.
The CRJ-200 is pathetic, but even it will climb pretty will to 12000-15000 if flown properly.
The SAAB2000 would do pretty well, but would also give up a lot of airspeed to get that rate. Can't do that is the CRJ.
