<p>Ice accretion on a probe (12) is detected by determining the change of frequency of a vibrating type ice detector or sensor (14, 16) as ice starts to build up. The rate of change of frequency is determined (24) and is combined with parameters including air velocity (28) and air temperature (30) for providing a signal that indicates liquid water content in the airflow as well as ice accretion on the ice detector (14, 16).</p> |
