This is correct except with certain mechnical failures.
The only time to put the 3B pump on to assist the gear door is if you needed the gear down before any flaps were selected. Proved several times that it was very possible to do 250 to the marker in the CRJ-200. Fun airplane!

I regards to your question, the 200 has flap issues. Restricting to 200 KIAS is expected to reduce the number of FLAPS FAIL problems.

One more thing keep in mind when slowing down at flight idle with full boards deployed. It gives you a very narrow margin above the stall protection system (SPS) as you approach 200 KIAS clean. I once had the SPS briefly activate while descending and slowing to 200 during an approach. I was at flight idle, with full boards, and just before achieving the required 200 KIAS for flaps, we entered a small cumulus cloud. The sudden jolt of light turbulence was just enough to trip the shaker.
I’ve since noticed that you tend to be below the green reference line when approaching 200 KIAS clean with full boards deployed. You know, the green line that everyone says is only valid with full flaps in the landing configuration, but perhaps the validity of the green line is a debate for another thread. I’ve heard and read conflicting things concerning the green reference line.

Call it a pride/ego thing; with proper descent planning you shouldn't NEED to use spoilers and with the new flap speeds its becoming increasingly more necessary.

Far too many pilots (IMO), when given a crossing restriction 75-100nm down the road, will immediately spin 1000-1500fpm down and start the descent...when any airplane equipped with advisory VNAV could just as easily have the descent angle set at 3.5-4.5 degrees and follow the snowflake down for fuel savings.
