Thanks CPRich, for the useful information regarding Thermawing and Delcam/GKM Aerospace. By heating the 787 leading edges only it seems like Boeing missed an opportunity for an on time winter operations aircraft. Nearly 90,000 flights were cancelled in winter 2010, due in part to time requirements for de-icing costing the airlines $600 million reference bloomberg article. http://www.bloomberg.com/news/2011-0...ellations.html
