The Challenger is like the old DC-9 short body A/C with and the F-28. Jets with no leading edge devices and therefore, extremely sensitive to icing contamination.
Bottom line......less margin to a stall. Never consider taking off with wing contamination on the above aircraft. Of course many will say that you never should with any aircraft and of course those are the rules, but it does help to be knowledgeable on which A/C are more vulnerable and why.
