Super-critical wing, found on more "efficient" designed aircraft, ie mooney's, commanche's, columbia's, are more adversely affected by ice than say that big fat wing on a cherokee 6, navajo's, caravans, etc... The only designed wings that prevent ice better than others is turbine aircraft, with heated leading edges. Assuming they are turned on. Tail icing is really more important than the actual wing ice, which tends to be over-looked and forgotten about by most pilots. Tail-stalls are very serious events, and usually come before the wing stops flying in every case.

As far as information, the fed's have plenty of Icing info through advisory circulars, and video's etc.... As far as the DC-8, I have no idea. It is a large aircraft, so I would put money that it does fine in most moderate icing situations, but no airplane does well with accumulation prior to take-off
