scope:

This report provides a list of companies that produce ice detection systems. Every effort was made to provide a complete list of companies and ice detection systems. Each company included in this report has been contacted and has provided the information used herein. The systems cited in this report are available and/or in use as of January 1993. The sections in this report entitled "Promising Technologies" include systems that are in development.

Information in this report is categorized into four sections: lnflight Ice Detection Systems, Onground Ice Detection Systems, Combined Onground and lnflight Ice Detection Systems, and Related Technologies. lnflight ice detection systems generally incorporate a probe or intrusive type of sensor. These sensors are mounted so that they are exposed to free airflow while in flight. They are designed for detection of environmental icing conditions and are not location specific. Current onground ice detection systems generally are used to detect ice at a specific point on the aircraft. Combined onground and inflight ice detection systems are systems that use the same technology for both applications. Related technologies describes systems that have some relation to ice detection technology. Following each of these four sections will be a subsection entitled "Promising Technologies." Here related future technologies will be discussed. Within these sections information will be organized alphabetically by company. Information about each company includes a brief theory of operation of the ice detection system, a description of specific devices, technical specifications, and a point of contact through whom additional information may be obtained.
