Not to hijack the thread but, huh? It obviously doesn't need ice protection since there hasn't been a CRJ or CL65 crash due to a tailplane stall... Should we say the same about the other manufacturers that don't anti-ice their tails...?

Especially considering that no ice protection on the tail is normal for high flying turbine aircraft. Check out a 737. It has to do with the limited exposure to icing conditions as compared to a prop or t-prop.

Limited exposure or not, I picked up severe (yes, severe) icing on approach to DEN. Even w/tail anti-icing on the Jungle Jet there were four inches of Rime in 20 seconds covering the aircraft. Glad I wasn't in the CRJ...Limited exposure? Thanks but no thanks!

No anti-ice on the tail of the 170 either.

I've picked up some serious ice on the tail of the CRJ and never noticed a difference in handling. No biggie. I'll try to dig up the ice certification videos for the Challenger. Trust me- they build up a heck of a lot more than 4" of ice on the plane (all surfaces) during the certification tests. Those guys have to have guts to fly behind a tanker spraying water at FL300.

You can say that again...! I'd be very interested to see the numbers actually, if you can find 'em.

Still trying to find that info... If I do, I'll start a new thread. Here's a cool pic of how they do it though:

That is one helluva photo! Is that a Saab 2000?? I've got about ten min's in one of their Level D's :D

Yes that is a Saab 2000, and from people that I have talked to who have flown, quite possible the best TP ever built, too bad the RJ had to come along and ruin the chance of flying that.

Pretty sure there was a hard landing by Skywest where tail icing was a contributing, if not the main, cause...

The 727 didn't have tail anti-ice either, but I've seen them completely iced up before...just like a CRJ tail. Just because there hasn't been an accident for tail stall (yet) doesn't mean it wouldn't be prudent to have tail anti-ice protection. The Beechjet has a known tail-stall issue related to icing (thing becomes a friggin' lawn dart!) and IIRC an inop tail heater is a no-go item.

I mean let's think about it, the airplane was designed by Canadians but it is absolutely horrid for errant EICAS messages when it gets cold-soaked and the flap fail issue has (in part) been attributed to slush/snow working its way into the system.
