CRJ Series Icing Concerns and Studys

[BrickTop]

Those of us who fly The CRJ series know of its claimed ability to prevent Ice accumulation on the tailplane an thereby unheated tail surface. Even with over 1000 hrs in type I have spent hours looking for research and testing on this theory and am looking for people with REAL HEAVY icing operational stories and aerodynamic knowledge to offer explanation to this wing design AND your personal experience with its handling of freezing rain sleet ETC. Any links or feedback is appreciated.

Been in heavy icing on several occasions. I have over 5k hours in type. The plane does a great job in icing as long as you follow the manufacturers recommendations. It is a well designed and well built A/C.

The 727 also had no tail anti-icing, because Boeing said aerodynamics were such that ice didn't accumulate there.

Name the jets that have ice protection on the tail? not being a smarty just curious.

EMB 145 has a heated horizontal stabilizer. The vertical is not heated though. It doesn't get ice because the engineers commanded it not to accrete ice.

Tat

I was under the impression that the higher airspeeds caused the surface friction to maintain a temp greater that what is required for ice accumulation to occur. I have forgotten the speed (235 or?) but I alwaysed checked the TAT and it was well above 5 degrees C. Maybe it is simple as that?

Chuck Norris doesn't get icing... the ice gets Chucked

I've seen plenty of ice on the vert. and horiz. stabilizers. Supposedly, it’s not that ice will accrete, it’s that it won’t exceed a point that would create a safety hazard. Anyone know what that point is?

 

[CFI2766]

Nope, not a single worry about icing on the ATR...

 

[BE400]

I was on the ERJ-135 out of TOL and the engines were icing up. It was fun watching it shed into the engine after the crew turn on the anti-ice!

I've seen plenty of ice on the tail of a CRJ200. I have also flown MU300/BE400's with normal and emergency tail anti-ice/deice. It was so important to keep ice off the tail, that it had an emergency de-ice.

You mean you didn't want to fly a tail-stalled lawn dart when you called for flaps 30?

 

[redflyer65]

It does accumulate ice during slower airspeeds in extended icing conditions. I believe this happened with a Skywest crew. Missed approach while flying in icing for a long time. Came back around while staying IFR and had no elevator authority during the flare. That's the scenerio that will get you in trouble. Refer to the QRH for ice removal.

That's another reason why I hate the beech jet/ diamond.

They'll let you experience at the flight safety in ICT. It's enough to make you remember to pay attention.

The thing was built by the Canadians, the one thing it does well is fly in the winter. Wait unless its too cold then the flaps fail and we get to land at 170 somthing kias.
