Title:Aircraft Icing Directory
Issuing Committee:Ac-9c Aircraft Icing Technology Committee
Scope:This Aeronautical Resource Document (ARD) identifies the personnel that are active in the field of aircraft inflight icing. These people, and their companies or organizations, support research and development that provide a better understanding of the problems of inflight icing, an provide equipment to make flight in icing conditions safer. This directory is intended to make communication among those in the field easier and to encourage advancements in ice protection technology. While the directory is extensive and current at the time of printing, there will be changes with time. However, the information contained herein should provide a good starting point for contacting other icing experts.
