Those are probably total times in which case I'd say it wasn't an experienced crew by any stretch.
People must have great eyes to know how a plane is coming down at night at probably 200kts with 3 miles of visibility.
According to CNN it was 3mph of visibility which would give them plenty of time as everything would be in extreme slow motion.
We get this caution light all the time in Decent in the Dash 8 300 when the bleeds go from LP to HP on a flight idle decent. Boots are still effective so no problem existed in the Dash 8/300 series. If you want the caution light to go out, just have to add alittle power.
For whoever mentioned green on green, most of those rules are only 100 hours per seat, so a 3 year captain and a 1 year FO would be no where near this.
Common for the -100/-200 series also. Rare to have it stay on after the valves cycled. If it did, it was written up.
deHavilland published several tailplane icing bulletins for the Dash-8 series in the mid-1990's after NASA's research used the DHC-6 (remember those videos in Recurrent?)
After the Eagle ATR Roselawn crash in 1994 (we're you at PDT then Surf?), deHavilland published a bulletin to operate in icing conditions with the boots cycling continuously (fast mode). I don't know if that applied to the Q400. I've been gone from PDT for 5 years and don't know if that is still SOP there.
The Dash-8 carries ice very well and not only can you see it, you can hear it as it builds, disrupting the normal slipstream airflow around the cockpit and on the wiperblades. If we carried ice on approach, we always bumped the ref speeds up, as recommended for tailplane icing.
This BUF crash is heartbreaking. My condolences to the families of the crew and pax and their loved ones.

True, I believe the NTSB will really be looking hard at Total Time in Type.
Does Colgan have Green on Green rules?
Its still hard for me to believe ice brought them down.
I'm inclined to agree.. but theres no doubt theres some denial on my part as I fly these things in a boatload of ice every day.

On another note a cnn analyst just said that conditions were prime for carb icing..
