Earlier discussions in link below of considerable interest. This time from a previous Tech Log Forum. Note comments by John Farley the British test pilot. He died a couple of years ago. The links to the severe icing accident to a DC3 really opened my eyes.. Read pages 46 onwards of that CAB accident report to the North-West Airlines DC3 that went in on short final due severe icing at Moorhead, Minnesota USA refers.
Can you imagine flogging around a bad weather circuit in less than a mile viz with an inch or more of rime and glaze ice on the wings and tail, while using a baster to scrape the ice of the windscreen, is the stuff of nightmares. But SOP in USA those days.
