On the 22^nd October 2020, the SENS4ICE research programme, which focusses on the detection of SLD icing conditions, held a Symposium as part of the SAE AC-9C Aircraft Icing Technology Committee meeting.  The symposium was held virtually but was attended by more than 100 people from across industry and academia.  Results were presented from a successful series of development icing wind tunnel tests that were performed at the RTA facility in Vienna, Austria.  Presentations given by the partners can be found here.
