This actually works in the 200...and believe it or not STILL leaves you with a bit of excess speed and a float.
But a 900...the only way that works without an absolutely backbreaker of a landing is if you're coming across the threshold too high/fast.

If you understand how to manage your descent rate it works just fine in a 900 as well.

Unless maybe you guys are just flying empty 900's around the country, I suppose.

If you are pulling power at 50 and floating gently to the ground in a 900 you are coming across the threshold with too much energy. There's really no way around it. If you are coming in on speed...the bombardier recommended vref speed...when you chop the power it's coming down.

Then please enlighten us because a lot of us have flown that airplane since it came out and the only guys I know who did that carried to much airspeed or nosed it over to gain airspeed. I flew with one guy who would chop the power at 100 feet, nose it over, and then flare while using the trim to assist. He’d be almost full nose up trim as he touched down. I would nearly crap my pants, but he would grease it on every time. Just because it can be done doesn’t mean it should

It was the way to land if the elevator cable snapped. Had that happen to a buddy of mine in a 172. He landed, but bounced about six times before stopping.

Thrust/Airpseed. I fly all three variants of the Canadian pencil tube, they teach in training to pull thrust at 30ft but I as well had "big jet syndrome" (LOL) and would leave the thrust in too long. This combined with flying the top of the bug and a nice gust of wind = 2,000ft float...... I was cured doing billions of MDW turns in the 700 to realize to control airspeed over the threshold. I spent weeks diligently observing the airspeed over the threshold to finally figure out how much that plane will float if you are at the top of the airspeed bug with thrust coming to idle at 30ft... youll never get that plane on the ground.
Also something to think about, I know many CRJ operators have performance Ref speeds as Ref+5... which again, that 5 knots can increase landing distance 10-15%. Also Also, out of technique, If there is a gust, I still will leave the bug at Ref and fly the +5 or +10 to make sure I can control the speed back down to Ref over the threshold to alleviate floating. Seems to work so far.
