A unique, publicly available database regarding supercooled large droplet ice accretions has been devel-oped in NASA Glenn’s Icing Research Tunnel. Identical cloud and flight conditions were generated for five different airfoil models. The models chosen represent a variety of aircraft types from the horizontal stabilizer of a large trans-port aircraft to the wings of regional, business, and general aviation aircraft. In addition to the standard documentation methods of 2D ice shape tracing and imagery, ice mass measurements were also taken. This database will also be used to validate and verify the extension of the ice accretion code, LEWICE, into the SLD realm. Introduction The crash of an ATR-72 in Roselawn, Indiana on 31 October 1994 due to supercooled large droplet (SLD) icing focused attention on the need to better understand this condition. Still on the National Transportation Safety Board’s (NTSB) #1 Most Wanted Transportation Safety Improvement in Aviation (ref. 1) is to
