2005/06/07		 AIRCRAFT_ICING_INTENSITY TRACE The rate of accumulation becomes perceptible; trace. The rate of accumulation is slightly greater than the rate of sublimation. It is not hazardous even though de-icing/anti-icing <EQUIPMENT> is not utilized unless encountered for an extended period of time (over 1 hour). 2 IR [AIM, 7-1-22, b, 1] [WMO306, Volume I.2, Part B, Code table 0-20-041:10]
