The ERJ doesn't have leading edge devices yet we come in at fairly slow speeds (125-135) with a normal +1/+2 pitch attitude. I think the CRJ had some problem during flight testing (someone correct me if I'm wrong) and subsequently approach speeds were raised to avoid whatever problem they encountered. It seems like an artificially high approach speed and not really the stall speed plus 30-35%.

The CRJ Vref speeds are inflated a little bit because of the "super-critical" wing, but even at a normal speed it would still be pitched nose-down.

If memory serves the RJ did not use 1.3 Vso for ref. It is inflated, but I don't remember the percentage or the reason.

Every time I ride as a passenger on the CRJ, I enjoy it. I guess I haven't been exposed to much, but that thing pulls on takeoff! I'm surprised to hear it's underpowered because it feels like it accelerates pretty nicely. The truth is there were only about 6 people in the airplane the day I flew so it must've been due to the lower weight on the short hop from PHL-LGA. The beast is definitely the 757 though. Textbook short field takeoffs out of Toncontin Int'l (Tegucigalpa, Honduras) are just simply amazing. That plane CLIMBS. |

The CRJ is only underpowered up at altitude. Down low, the thing is a rocket ship and will outclimb pretty much anything except a 757 up through 10,000 ft.

PCL_128 said, "...and will outclimb pretty much anything except a 757 up through 10,000 ft." I'm gonna have to raise the BS flag on that one. Source? I find it hard to believe that your new non-ALPA (sorry had to throw that in there) Boeing 717 doesn't outclimb the Fischer Price Jet.

I've been told if you really want to fly a rocketship, fly a learjet. I hear the older ones had even better climb performance. I'd say Zap and mikecweb probably outclimb most other jets. |

| Old Skool | Or just fly any airliner empty.....even an empty RJ can push 6000-8000 fpm below 10k.

| One time at flight camp... Anyway SkyW was doing some tinkering in CDC in the 700 a few years back. They let some of us instructors from the local flight school ride up front. The check airman were getting checked out in the 700. Needless to say all I can remember is "follow the snowflake" and "don't bounce my plane" being barked from the pilot in the right seat. |

1:56 seconds. Brake release to 10k. Lear 35, temps in the 30s, empty with 3,000lbs of gas.

| No "source," just personal experience from flying the Canadian-replacement-jet for nearly 4000 hours. A flaps-8 takeoff at normal T/O power will easily get you 5-6000 fpm with a light airplane. Quote:

I only flew the CRJ for a little less than 2000 hours, but I was never terribly impressed with it in any flight regime. The Learjet outclimbs every airplane i've ever flown even single engine (in the sim anyway). I have to admit though, i've been flying this thing for 3 years now and I'm sure that my memory of CRJs, Boeings, and Douglas have all faded with time. Much like when we reflect fondly on that high-school girlfriend, the mind tends to construct memories in the way we viewed them at the time, and not always as they actually were.

Oh, I'm sure the Lear outperforms the CRJ in every way. I guess I should have said that the CRJ outclimbs most jet airliners at low altitudes.

Touche'. Like I said, I don't remember the Boeing or Douglas well enough to compare them to my fading memory of the CRJ. Since you essentially fly a DC9 with 28,000 lbs of thrust per side (far more power than the original DC9-30), I'll have to take your word for it that the CRJ is better in initial climb... ...But I still think it's a piece of crap.
