These proceedings contain 33 papers. The symposium was composed of the following sessions: Cold weather operational experience and requirements 6; System design considerations 14; Fuel effects and lubricants behavior 5; Icing conditions and testing 8. Questions and answers of the discussions follow each paper in the proceedings. The papers presented and the discussions represent a significant contribution to improved cold weather tolerant and anti-icing design and to safer aircraft operation in low temperature conditions. A case was also made for advanced and larger dedicated testing facilities, and some specialized software developments were indicated. Partial contents: Vulnerability of a small powerplant to wet snow conditions; Ice tolerant engine inlet screens for CH113/ 113A search and rescue helicopters; Cold starting small gas turbines--An overview; Cold weather ignition characteristics of advanced small gas turbine combustion systems; Cold weather jet engine starting strategies made possible by engine digital control system; Cold start investigation of an APU with annular combustor and fuel vaporizers; Effect of fuel properties and atomization on low temperature ignition in gas turbine combustors; Influence of fuel characteristics on heterogeneous flame propagation; Vertical and horizontal aircraft soundings of icing relevant cloudphysical parameters; and Developments in icing test techniques for aerospace application in the RAE Pyestock altitude test facility.
