What is it about?
The paper demonstrates how an ice detection system can be set up, which doesn't rely on specific ice detection sensors. Moreover, in the project SENS4ICE a novel approach of hybridization of different detection techniques is introduced. In the proposed hybrid system, the direct sensing of atmospheric conditions and/or ice accretion on the airframe is combined with an indirect detection of ice accretion on the airframe by monitoring the change of aircraft’s characteristics.

Why is it important?
The new system is designed to discriminate between the most common icing conditions, which are defined in Appendix C of 14 CFR Part 25 (formerly known as FAR 25) / CS-25 and icing due to Supercooled Large Droplets (SLD) addressed in new certification rules under Appendix O of 14 CFR Part 25 (formerly known as FAR 25) / CS-25. SLD's have been the cause of severe accidents over the last three decades. It has become clear that improving safety is important for these icing conditions. Detecting such conditions reliably helps to ensure that future airplanes remain controllable in these conditions and can exit safely upon detection.
Perspectives
Working on the subject described was a pleasure, since we were able to show that the approach performed as we intended. We are glad that we could do this research in close collaboration with industry partners motivated to set up and to test the system for future application and industrialization.
