About 80% of takeoffs on the CRJ are flaps 8. Calling for flaps 8 on taxi feels like almost standard procedure.
And old trusty method of remembering a non-standard flap setting is throwing a empty cup over the flap handle. Works great!

The thing that stands out to me most on the transcript is the actions and leadership of the Captain post crash. In charge, decisive, calm, and commanding.
Oh, wait...
Any pilot who looks at something and says "I could never do something like that" is in fact an accident waiting to happen. YES, you could do something stupid. The NTSB record is full of professional experianced pilots who made simple rookie mistakes and died because of it.
A constant attitude of humility will keep you vigilant to watch for your own mistakes. As many CRJ pilots have said, this accident was partially a result of a very simple common mistake that all of us have made on several occasions.
Moral of the story? The abort may be more dangerous than flying the plane.
Your milage, of course, may vary...
I respect him for being honest about it. He screwed up and he admitted it.

This proves that even high time guys make mistakes.
Absolutely true. Moreso it proves that nomatter how good we THINK we are, it could happen to any one of us.
The CRJ would have done the same thing.
If flaps zero had been set.
Instead, flaps 8 were set.
You had the same thing in the ERJ; you could takeoff with flaps 9, 18 or (I think) 22, and you wouldn't get a takeoff config warning on any of them.
Now what if you needed flaps 18 and you put in flaps 9 like you do 99% of the time? No takeoff config warning.
Maybe you get that and I'm missing it (I'm kinda tired right now, so that's possible), but the CRJ and ERJ will both squawk at you if you don't set ANY flaps.

If you can an engine, you might be in a different situation, but with a two engine takeoff in the ERJ, folks have proven that on some runways, you won't hit anything if you takeoff with flaps 9.

And they F'ed it up, it looks like. Right around 16:08. Calls for "flaps 20. Taxi." Then, at 16:09, they start talking flaps EIGHT numbers. Both pilots even confirm flaps eight not a minute after CA called for flaps 20. Shouldn't have given them a "Config flaps" warning, though. The plane doesn't know what V-speeds are set. If company policy or a majority of the takeoffs you do are flaps 8, I could see this happening if you're tired/complacent/distracted. Can bite you in the ass if you set flaps 20 speeds and flaps 8 for takeoff. I know at least one of them said he was tired. They also checked the "T/O Config" and according to the transcript, they were getting an okay message. You'll get that if you're in flaps 8 or 20 as well. I almost wonder if they set flaps 8, then realized on the t/o roll, moved the handle, and they got the "config flaps" because the flaps were MOVING during the takeoff. Don't know if that'll happen or not, but it's a possibility. If you're gonna get a config warning in the thing, it's normally right as soon as you start moving once the N1s spool up. I've got a config warning ONCE, and it consisted of slapping the TRs to idle, and the thing stopped. For some reason, we still got a "t/o config okay" message and no "flight spoilers" status message with the spoiler lever in the first detent. It sure as hell told us "Config spoilers" though.
I'm not sure how many CRJ operators have similar procedures but at PSA the flaps are part of the taxi check which is done (normally) while taxiing. Throw in a random radio call causing a distraction and you get this.
My guess is that with both engines running and flaps 9, this CRJ would have been airborne with no problems. Had they had an engine failure with flaps 9 speeds set at V1-10 kts, they probably would have gone off the end.
we're now supposed to do the taxi check prior to moving the aircraft
How does that play out with single engine taxi procedures?
I was sorta expecting some huge mandate to come down from the FAA after this one...
Safe Taxi Tips and Preventing Wrong Runway Departures
Notice Number: NOTC2090
The Commercial Aviation Safety Team (CAST) strategy is to significantly increase public safety by adopting an integrated, data-driven strategy to reduce the fatality risk in commercial air travel. The CAST model:
One of the focus areas for CAST Safety Enhancements (SE) is runway safety. Recently updates to runway safety programs were added to the CAST website, which include information on PREVENTING Wrong Runway Departures and global Best Practices for REDUCING risks while taxiing.
- Identifies the top safety areas through the analysis of accident and incident data.
- Charters joint teams of experts to develop methods to fully understand the chain of events leading to accidents.
- Identifies and implements high-leverage interventions or safety enhancements to reduce the fatality rate in these areas.
Uploaded here is a nice brochure put out by the FAA on Preventing Wrong Runway Departures, and the Supplemental Implementation Plan (SIP) for CAST Safety Enhancement 60, "Commonly Used Safe Operating Practices for Taxi Safety."
