When available on market and deployed in regular operation, an instrument of the MRAS class will have applications in general aviation, military operation, search and rescue operations. It could become a part of such weather reporting systems such as ACARS (Aircraft Communication and Report System), or private TAMDAR (Tropospheric Airborne Meteorological Data Reporting). It is conceivable that the private weather data provider, such as WxWorkx (www.wxworx.com) currently providing mobile data service to public through the XM radio channel will be interested to include the local, more detailed information about icing condition into their data service. Corporate aircrafts and individually owned small engine aircrafts, helicopters operating for oil rigs, military and Coast Guard helicopters are potential customers for such devices too. UAV platforms might also be interested in technology that will allow them to seek routes through icing conditions. NASA aircrafts, especially turboprops and helicopters can use the proposed sensor in everyday operations. NASA research aircrafts could potentially use the instrument for in-flight icing research or for general applications where flights in or close to icing zones are required. The technology proposed here will improve aerospace system safety, efficiency, an could lead to more effective use of national airspace.
